What is the Best Cordless Finish Nailer?

A finish nailer is a powerful tool that is specifically made for both experienced and DIY home users. The finish nailer uses relatively smaller nails than other cordless nail guns but is designed to handle different jobs. A finish nailer is the best bet for installing trim, crown moulding or even suitable for specific cabinets and furniture finishing.


What is the best cordless finish nailer?

A ‘finish nailer’ broadly refers to one with a 16 gauge, which is a little thicker nail than the 18 gauge brads. There can be a bit of confusion due to the fact of the higher the number of gauges, the thinner the nail will be. This is due to the number of nails that you can fit per inch (for example, 16 gauge = 16 nails per inch and 18 gauge = 18 per inch). Therefore, you need the right nail for the proper work, so that the structural integrity of the material is not splinted or harmed.

Cordless finish nailers are made by different and various reputable brands such as Dewalt, Makita and Porter-Cable. Still, all these brands offer similar to little different features.

What is the greatest advantage of Cordless Finish Nailer?

A finish nailer is a versatile commodity which can also be used for various tasks such as moulding, decorating, roofing and many other jobs. This can also move the nails from thin wooden panels to dense concrete material and other various materials.

Difference between angled and straight finish nailer

Angled finishing nailers are made to be for narrow or tight spaces project. This type of finish nailer is durable to drive more substantial gauged nails. Straight finish nailers, on the other hand, are used within open spaces, and it was built with sharper nails.

Features Of Best Cordless Finish Nailer

A cordless finish nailer is a durable and versatile tool to perform a range of tasks ranging from the installation of trim to the assembly of cabinets and furnishings. It is a reasonably robust tool that is built to drive comparatively smaller nails. Here is a great article on home newtools best cordless finish nailer

Below are the key features of the best cordless finish nailer:

1. Size and Weight

To finish work is usually a multi-day, all-day task. Which means you must hold your finish nailer device in your hand for extended periods. A cordless model doesn’t have a wired cord or pneumatic hose that you need to bring and handle with you. That lowers the stress on your wrists. Although, if your finish nailer is bulky, this might have an irreversible effect on your hand. On some models, the battery can add considerable weight to the tool. The greater the battery size, the more it will weigh and the larger it will be.

A cordless finish nailer needs to get into tighter spaces and work at odd angles compared to other nailers, so size is essential. Angled versions reduce the tool’s total height and can make use in tight spaces more straightforward. Search for a smaller, cordless finish nailer with a lighter, state-of-the-art battery that weighs as little as possible to help you continue to work for longer without hand fatigue.

2. Trigger Operation

There are two primary forms of trigger: bump fire and subsequent action. Faster is a bump-fire. You keep the pressure on the trigger and press the piston in the nail where you want to drive. This is quicker, so losing track of it is easier, and there is a higher chance of accidental shooting. A sequential operation allows you to release the trigger between the nails and press it in again before the next nail is pushed. It’s slower, but it’s a little safer and controllable.

Needless to choose either one or the other. There are many models on the market which accommodate both. And, if you’re not sure which one you want, or if there are moments when you’re going to need one, look for one that has both in features. These combination finish nailers either have some internal mechanism allowing you to switch between operating modes, or they enable you to switch triggers out. Others that will enable you to change triggers also don’t come along with the extra trigger. You’ll have to buy an extra one.

3. Quality

Although, many people believe in brand reputable when choosing tool quality. This is because a reputable company always protect their name and to do this, they keep on producing a quality product.

While there is no foolproof way to upfront predict tool quality, but reading feedback and trusting a well-known organization minimizes the risks of getting poor tool.

5. User friendly

We strongly recommend that you read reviews and check product details to find a model that will comfortable in your hands, given the simple cost of a finish nailer. This is a method that is expected to deliver reliable results depending on how you treat it. The standard of the job starts with your hand. It is believed anybody will want to choose a  non-cumbersome finish nailer.


6. Lighting

With LED light features, a finish nailer makes its way within dark spaces such as cabinets or low-light areas, like baseboards. A cordless model with LED lights will directly transmit shadowless light to the surface, so you will see what you are doing without external lighting.

7. Higher Nail Capacity

This is one of the essential features a best cordless finish nailer you have. Having higher nail capacity will assist you in concentrating on the work through the elimination of frequently nail refilled. Another benefit of higher nail capacity is that it saves time.

8. Nail Depth

Precision hitting is outstanding as firing is. Finishing nailer is expected to hit the appropriate depth of the nail. Many finishing nailers come with an adjustable depth sensor that helps you to set precision depth. So, when choosing your finishing nail to ensure it offers consistent nail depth across a variety of types of materials.

9. Jam Clearing

Tool-free jam clearing is one a great feature expected to look for in a finish nailer. Nail jam may occur at a time, and if your nailer does not possess smooth jam-free. There may be some difficulties in hunting down the nailer.

Although, jamming can be held to a minimum by keeping your nailer in place and making sure you use the right nails.

10. Warranty

An extended warranty is an indication that the manufacturer has faith in its materials and manufacturing. Search for the longest available warranty and a money-back guarantee just in case you are not satisfied with tools.

Final Word + Recommendation

Finish Nailer is commonly regarded as a technical tool, but this innovative tool has significantly changed the finishing game. This is the reason almost everybody or hobbyists are now using the device to execute their various projects. A cordless finish nailer is a versatile woodworker tool that helps to punch the nails seamlessly, and gives the woodworks a clean and finished look.

Cordless finish nailers are fantastic, and there are plenty of models available which you can select the right cordless finish nailer to suit your work needs.

How To Tackle Vibrations Using A Coriolis Mass Flow Meter

Coriolis mass flow meters are acknowledged or well-known as an extremely precise and accurate flow measuring device. Plus, it offers plenty of benefits than other instruments. But take note that every measuring principle has its obstacles, and it is also true for the Coriolis principle.

For the most part, it can be difficult and hard to use Coriolis devices in most low flow applications in industries manufacturing large and heavy products. In these applications, you might have to face all types of vibrations.

Thus, the question is, how can you deal with these vibrations using the coriolis mass flow meter. For a little help, we will walk you through how to deal with all types of vibrations. So, take a read!

Coriolis Principle

This flow measuring device provides multiple benefits and advantages compared to other measuring instruments. First and foremost, coriolis flow meters calculate or gauge direct mass flow.

For many industries, it is a critical feature because it removes or eradicates inaccuracies induced by the fluid’s physical properties or characteristics. Aside from this, coriolis flow meters are extremely precise and accurate, have no mechanical parts in motion, have immense repeatability, a towering dynamic range, and many more.

The coriolis principle is simple yet very effective. Its operating principle is all around us in this world, such as the rotation of the earth and its impact on the weather. Coriolis flow meters have a tube powered by a fixed vibration. So, when a liquid or gas traverses through this tunnel or duct, the mass flow momentum will, more often than not, create a change or alteration in the vibration of the tube.

Then, the duct will contort culminating a phase shift. This shift can be calculated or computed deriving a linear output corresponding to the flow. As the coriolis principle calculates mass flow regardless of what’s inside the tube, it can be, for the most part, promptly implemented to any fluid traversing through it, gas or liquid.

While the thermal mass flow instruments are reliant on the fluid’s physical properties, thus, similar to the phase shift in frequency between outlet and inlet, it’s possible to calculate the actual natural frequency change.

This frequency change is incongruity to the fluid’s density, and it can derive a further signal output. It’s possible to calculate the volume flow rate having computed both the density and the mass flow rate.

How it Works

Coriolis mass flow meters calculate or gauges the mass via inertia. A dense gas or liquid moves or traverse through a tunnel or duct which is pulsated by a small actuator. This vibration generates a measurable contorting force on the duct corresponding to the mass. More advanced models of this flow measuring technology apply dual-curved tunnels for lower pressure drop and higher sensitivity.

Although considered or known as the most precise flow meters, coriolis mass flow meters are prone to errors or inaccuracies when bubbles are existing in the liquid. These bubbles can produce or generate splashing inside the tube, make noise, and modify or alter the energy required for tube vibration. Huge spaces boost the energy required for tube vibration in excess and can end up in complete failure.

Impact of Vibrations on Accuracy of Coriolis Flow Meters

In manufacturing, factory, commercial, business, trade applications, all types of vibrations with various sizes are eminently common. Coriolis mass flow meters calculate a mass flow through a vibrating sensor duct, which variation gets purposely out of phase when the gas or liquid traverses through.

This technique or approach is relatively susceptible to unnecessary vibrations with a recurrence close to the sensor tube’s resonance frequency or a towering concordant of this frequency. However, it depends on the design of the sensor tube.

The odds of the frequency of these unnecessary vibrations is greater than in an industrial environment. Manufacturers of coriolis mass flow meters do their best to minimize the effect of vibrations on the measurement using some technical solutions including pigtails, active and passive vibration compensation, mass inertia, different sensor shapes, dual-sensor tubes, and higher driving frequencies.

In other words, vibrations can affect the accuracy of the measurements of coriolis mass flow meters. However, only if the frequency of the vibrations is close to the concordant frequency.

Types of Vibrations

In industrial applications, vibrations can be produced by usage-based vibration sources, building-based vibration sources, and environmentally related vibration sources. These vibrations move or traverse through a medium such as the fluid itself, through pipes, in the air, or the floor. If any of these vibrations disrupt the frequency of the device, then the output could be incorrect.


It is helpful to determine the sources to lessen or reduce the effects of unwanted vibrations. Oftentimes, it’s possible to move the measuring device or instrument just a little bit, take advantage of huge mass blocks, use suspension alternatives, or use flexible tubes.

Biomass Conveyors: An Overview

A well designed biomass conveyor system should take into account the variability of the material and provide the consistent and reliable flow that is crucial to power generation. Depending upon the type of boiler and conversion system, the fuel is either transported directly to the powerhouse via a belt conveyor, or first processed in a chipper/grinder to produce a finer texture.

For example, municipal solid waste is deposited into pits where cranes mix the refuse and remove any large, non-combustible items. Sometimes, it is further processed to remove ferrous materials, glass, and other non-combustible materials.


For large pellet-fired biomass system, rail dump method is very common where railway tracks are constructed to transport biomass. Station is specified for train and fuel receiving bins are typically located below the track and rail cars dump into bins, either directly or through a rotary dumper. Fuel received is then transferred by belt conveyors to the biomass storage bins.

For small particle size, pneumatic conveying system offer greater flexibility in routing than traditional belt conveyors. Equipment specific to pneumatic systems include positive displacement blowers and rotary feeders that function as air locks.

In a typical biomass thermal power plant, the initial process in the power generation is biomass fuel handling. A railway siding line is taken into the power station and the biomass is delivered in the storage yard. It is then unloaded from the point of delivery by means of wagon tippler. It is rack and pinion type. The biomass is taken from the unloading site to dead storage by belt conveyors. The belt deliver the biomass to warehouse.

The transfer points inside the warehouse are used to transfer biomass to the next belt. The belt elevates the biomass to breaker house. It consists of a rotary machine, which rotates the biomass and separates the light inorganic materials (viz. plastic or other incombustible particles) from it through the action of gravity and transfer it to reject bin house through belt. The belt further elevates the biomass until it reaches the crusher through belt.

In the crusher a high-speed 3-phase induction motor is used to crush the biomass according to the requirement, for gasification size range is usually upto 15-20mm, while for biomass-fired boiler, size of 50mm is acceptable. Biomass rises from crusher house and reaches the dead storage.

Cost-effective production of biomass energy is very much dependent on efficient handling of available biomass sources, as well as the efficiency of each process. An important, but often overlooked, area is the efficient receiving of different types and different capacities of biomass as it enters the plant and then conveying this material to the production equipment.  In many cases, the space available for biomass handling is limited.

Receiving equipment can be installed in a pit or at the ground level. The size and volume of the receiving pocket can be suited to vehicle volumes or turn-around times. The receiving pit can be used as small buffer biomass storage or as an emergency or mixing pocket.

Belt conveyors are an economical and reliable choice for transferring biomass over long distances at high capacities with lower noise levels. Designs range from simple, open configurations to totally closed and washable conveyor galleries. Well engineered conveyors have the maximum safe distance between support legs to minimize the cost of civil construction as well as reducing the number of obstructions on the ground.

Chain conveyors are a reliable choice for transporting unscreened or dusty biomass, or when the available space is limited. Screw conveyors are a very economical alternative for transporting biomass over short distances.

Biomass conveyors are an integral feature of all biomass conversion routes

Nowadays, automated conveyor systems are getting traction around the world. Fully automated fuel handling systems employ a biomass storage bin that can hold upto 50 tons (or more) of biomass. The bin is filled by a self-unloading truck with negligible or no onsite staff assistance. From the biomass storage bunker, the fuel is fed automatically to the boiler by augers and conveyors. The fully automated system is a good match for biomass plants where maintenance staff has a large work load and cannot spend much time working with the biomass conversion plant.

Pellet-based hopper systems offer low costs for both installation and operation. In a modern biomass pellet boiler system, fuel is stored in a relatively low-cost grain silo and automatically fed, with no operator intervention, to the boiler or boilers with auger systems similar to those used for conveying feed grain on farms.

The fuel-handling system uses electric motors and is run by automated controls that provide the right amount of fuel to the combustion chamber based on facility demand. Such conveyor systems require minimal maintenance, around 20-30 minutes daily, for ash removal and maintenance of motors and augers, estimated to be about 20-30 minutes per day.

Shedding Light on Non-Destructive Testing with Ultraviolet Lamps

Non-destructive testing (NDT) can be simplistically described as a method used to conduct an inspection without moving or breaking the item or surrounding area under examination. Although not limited to medicine, aerospace, and industry, these three large sectors are particularly dependent on non-destructive inspection methodologies. One of the most helpful tools for NDT is the Ultraviolet (UV) lamp. Let’s take a brief look at the presence of UV lamps in NDT settings.

Non-destructive testing is a broad field

The definition of NDT can be quite broad unless one limits its description to a test, evaluation, or inspection, in a particular field of engineering or medicine. As well, the type of inspection that is required also comes from a long list of possibilities.

Non Destructive Testing

Fluorescent Magnetic Particle Inspection (FMPI or MT) and Fluorescent Penetrant Inspection (FPI or PT) are strongly associated with the use of fluorescent lighting and NDT.

Let the light come in

UV light is longer than X-rays, and shorter than visible white light, placing it into the 10 to 400 nm wavelength range. Known as black light, non-visible UV light can be harmful. The shorter UV-C rays, up to 290 nm, however, rarely reach the earth, and this is fortunate. Also be wary of UV-B rays, which are responsible for sunburns. The longer rays of UV-A, between 320 and 400 nm, are the least dangerous to humans.

In the past, magnetic particle penetrants used a mercury base, which became fluorescent with a UV-A light of 365.4 nm. This led to the requirement of today’s UV light sources for NDT. The standard requirement for a peak wavelength is between 360 – 370 mm.

The UV lamp advantage

One aspect of UV lighting that gives it the edge is that it provides visibility into the area under inspection where otherwise, there is none. The magnetic particles or penetrants that are applied to the surfaces of the areas to be inspected become fluorescent, providing visibility into the tiniest of flaws, such as cracks, breaks, and positioning changes.

What to look for in a UV lamp

There are UV lamps and then there are UV lamps. To achieve the most efficient, successful, and safe examinations, it is important to choose the correct UV lamp for the task at hand.

LED illumination

UV LED lamps are highly recommended for non-destructive testing. In fact, for the most part, LED lamps have replaced incandescent and fluorescent lamps, which may not be easily available in the near future.

UV Lamp

However, some legacy UV lamps can be modified to accept LED bulbs. UV LED lamps are lighter, making them very manageable. The bulbs are long-lasting, not prone to fading, and can be housed in cooler casings.

Handheld or stationary

The advantage of handheld UV LED lamps is, of course, their portability and their low energy consumption. However, unlike their predecessors, the mercury vapor bulbs, they do not offer the intensity and the wide beams that are required in some inspections.

Meeting the challenge, some UV lamp producers are using LED lighting to create stationary overhead lamps with intense, wide beam coverage, and adaptable frames, allowing easy vigilance over production in assembly lines. This is a low-cost alternative to frequently-replaced fluorescent bulbs.

The importance of a filter

With a peak wavelength between 360 – 370 nm, violet tail emissions of visible light above 400 nm can mask flaws and cracks with light glare. A filter improves visibility by providing more contrast.

Additional considerations

Science and engineering are always in flux. Similarly, developments in the field of non-destructive testing brings with it much to consider.

  • With the introduction of LED bulbs in UV light sources, dangers resulting from potential accidents in non-invasive fault-seeking, are no longer concerns. Burns resulting from filaments in mercury vapor are becoming a thing of the past. With less electrical demands from LED bulbs, power supplies can be lightweight, making the lamp easier to handle in tough conditions.
  • Just the fact that mercury will no longer be needed is enough of a cause for celebration.
  • Visibility with LED lamps is instantaneous.
  • For some conditions, a narrower beam is required. NDT requirements must lead the way when determining the lamp’s specifications for a particular type of inspection.
  • One challenge that designers are working on is the emission of heat flux at the emitters of UV LED lamps. This is a result of smaller technology with increased energy levels.

Non-destructive testing has broadened its scope over the years, giving rise to compliance standards for specific NDT applications. The most well-known compliance standard to look for in UV-A lamps for NDT with FMPI and FPI, is the ASTM E3022 standard. Whatever the standards of compliance are for a particular industry, non-destructive testing and its reliance on dependable lighting for inspections, is now an important branch of engineering in its own right.

How Machine Improvements are Driving the Renewable Energy Sector Forward

The renewable energy market is set to grow to more than $1.5 trillion by 2025, according to Allied Market Research. With its many constituents, biomass remains the leading form of the renewable energy market. This is due to the sheer number of places to source it from. But apart from the supply, there is another critical factor in driving the renewable energy sector forward.


The continued advancement in renewable energy harvesting machines ensures that clean energy remains viable and cost-effective. Hence, it is pivotal in the quest to turn the world’s power grid 100% renewable.

Reliable Renewable Energy Sources

Nowadays, the most efficient form of renewable energy is biomass, followed by hydroelectricity and wind. They’re the resources we depend on the most for our clean energy goals. Getting more of these renewable energy resources is the best chance we have at reducing our carbon footprint. This is something that leaders in the world of machines and tools are tackling right now.

Machine Advancements and Renewable Energy Harvesting

As it stands, the most productive renewable energy sources heavily rely on harvesting machines with moving parts. Turbines on wind and hydroelectric generators, as well as biomass harvesters and processors. These devices themselves cost energy to use. Also, if we grow too reliant on them and experience too many breakdowns, it could compromise the entire energy supply chain. Therefore, ensuring efficiency and reliability is paramount.


According to spiborescopes.com, this is thanks to tooling companies working closely with the energy sector. This helps them craft tools to their specifications. More Floating Offshore Wind farms are being erected. These wind farms have a greater capacity for energy production while being less intrusive. In fact, new compound harvesting vehicles are reducing the steps taken in making biofuel.

The Future Of Renewable Energy Harvesting

The renewable energy harvesting sector continues to advance in both production and technology. The fact that its market stayed steady while fossil fuels were evidence of that. This is all thanks to a strong support structure built by the machinery and tooling industry. It is also due to this intimate relationship that energy gathering will become more automated.

Soon, harvesting renewable energy will be passive as well as efficient. Many innovative automated energy harvesting devices are on the rise. These include trees fitted with photovoltaic cells. There are also companies developing pressure-powered generators. These can be placed under high-traffic roads and walkways.

Such devices have been dubbed the “ambient energy harvesters”. These devices owe their invention to important lessons in efficiency and reliability. Lessons that the machine and tool industry will keep learning as it helps the renewable energy sector reach maturity.

There’s no telling when we might see our power grid fully supplied by renewable resources. However, we may have just hit our stride in working towards that goal.

Picking the Most Efficient Air Compressor for Your Workshop

Air compressors are energy-generating appliances that can be used pretty much anywhere. When you have a workshop, you care a lot about the condition of all the appliances used in it and their efficiency because these are the tools that help you get work done. Buying your first air compressor, for any purpose, can be incredibly overwhelming. The specific details you should be aware of for each compressor can be complicated and confusing, which will leave you baffled as to which one will best suit the specific needs of your workshop. Here are some tips to help make that decision easier for you.


Choosing Between a Piston and a Portable Air Compressor

When it is time to choose an air compressor for your workshop, you are likely to come across numerous types of compressors which will make your decision even harder. However, for workshops, there are two popular and basic compressor types to choose between; piston and portable air compressors. According to Brett Patterson of Ablesales, a piston compressor is an excellent source of portable air supply for farms and workshops. Just like any other type of air compressor, the piston’s motor works on collecting the air in a set tank and pressing it with the degree of pressure needed. The more you use it, the more pressure the compressor will generate.

On the other hand, a portable air compressor does the exact same job as the piston compressor, just without the need for an air tank. The main perk of a portable air compressor is that it is easy to move around wherever you need it. It might not be as powerful when it comes to pressing the air, but it is quite versatile, especially if you have a large workshop where you might need it in different places at different times. It is also excellent in reducing waste that is harmful to the environment.

Consider the Size of the Compressor

Almost all workshops are known for having large machines and appliances. Essentially, an air compressor would be another machine added to your working space, so you would need to consider the size of the compressor you will be investing in to ensure the best efficiency and ease of work. Whether your workshop is big or small, you need to think about the load of work you are planning to do with the air compressor as that will determine the size of the tank required. Compressors that need an air tank are usually more efficient for more demanding workshops, however, they are quite large. On the other hand, compressors with small or no air tanks can be more suitable for workshops with small workloads and smaller working spaces.


Check the Features

Efficiency and durability are essential features that workshop owners or managers look for in their appliances. The durability of an air compressor determines how much work it will be able to offer you as well as the life span of its productivity. When you choose an air compressor, features like the coating of the tank and the strength of the steel build of the compressor itself should be at the top of your list. Read reviews on the supplier and manufacturer before you purchase to get a better idea of how reliable that specific machine will be for your workshop’s needs.

How is the Compressor Powered?

Workshop owners invest in air compressors to generate energy used in manufacturing products or powering certain appliances. However, the compressors themselves need to be powered in some way. Compressors can be powered by electricity, petrol, or diesel. Electric compressors are the most popular because of how energy-efficient and economical they are. However, they are not as powerful as their petrol-powered counterparts, which can be more reliable when it comes to pressing air. Diesel compressors are similar to petrol-powered ones, but they can be a bit more harmful to the planet as they emit larger amounts of nitrogen compounds and particulate matter, which pollute the air and contribute to climate change.

Investing in an air compressor can be beneficial for your workshop, regardless of how big or small it is. But when it comes to deciding which compressor is best suited for your needs, the choice can be challenging. Your best bet is to do some research in advance and compare different types, sizes, and prices so you can choose which best fits your needs and budget. It also pays to read up on the different power sources and try your best to opt for a unit that doesn’t contribute as much to environmental degradation.

How Can Oil-Free Air Compressors Benefit You and The Environment?

If you already have an air compressor, you will be aware of how they are an incredibly valuable tool for industries and DIY enthusiasts. Commonly used to power pneumatic tools but can be used for a variety of applications. Air compressors provide you with complete power over spraying, nailing, sanding and hammering at a fraction of the time it would take with manual tools.

You can also find these smaller sized air compressors everywhere that are very portable and best at doing small work. Bob Robinson of BestOfMachinery swears by these portable tools. “Small air compressors essentially push air from the tank in the unit, into the tools that you want to use for either DIY, hobbies or work purposes without the need to lug heavy stuff.”, he commented.

These machines can also be used for inflating tyres, auto repairs and even creating home-made snow machines. Sandblasters, impact wrenches, grease guns, die grinders and angle disc grindles can also be attached.

We all love our power tools and would be lost without them; however, we are becoming more aware regarding the issue of carbon emissions. Reducing our carbon footprint is one of the most important things companies and individuals can do in their lifetime. Small changes within your business and homes can be a great start to decrease our carbon emissions and help save the planet.

If you are looking to purchase your first air compressor or to update an existing model, Direct Air has created a guide on why an oil-free air compressor is a great choice, not just for the environment, but to help you save on energy bills. You can see their full range of oil-free air compressors at https://www.directair.co.uk/products/oil-free-air-compressors/.

Every air compressor requires lubrication in order to efficiently and safely draw in air to its cylinder, commonly using a piston movement. The traditional method to achieve this is using oil, while oil-based air compressors do have their benefits as they are more robust and can handle large-scale applications, they are higher in initial cost, harder to maintain and far heavier than their oil-free counterparts.

Oil-free air compressors gain lubrication through a non-stick coating, generally Teflon. As extra elements to hold oil are eradicated from these machines, they are far lighter and smaller than oil-based air compressors which make them ideal for applications that are not static. Due to less components, oil-free air compressors are often cheaper to purchase.

Oil-based air compressors must remain static and upright when in use, oil-free are far more versatile. As you do not need to consider the oil flow, they can be positioned wherever you see fit. They are also operatable at any temperature, oil can become viscous in cooler climates and can cause problems when attempted to start the motor, oil-free erases this issue.

With these benefits in mind, you can achieve even more with your oil-free air compressor by helping to reduce the use of fossil fuels maintain the planet’s natural resources. You can also make a direct impact on your running costs, saving you and your business money on your energy bills.

With an oil-free air compressor, all costs to collect and dispose of oil-laden condensate will be removed, not to mention the initial cost of the oil itself. These compressors are less wasteful as they do not require the replacement of the air/oil separator and filtration elements which are required to get rid of oil aerosols, these parts are notorious for wearing down quickly. You will not needlessly be sending these parts to landfill and be bearing the cost of new ones on a regular basis.

If you are worried about direct harmful emissions from your air compressor, oil-free air compressors produce the purest form of air which will reduce any negative impact into the atmosphere, great for the planet and for those working around it. You will also not have the trouble of potentially contaminated products from oil spillages during projects.

A big bonus of oil-free air compressors is that they are safer than their counterparts, as there is no oil, you eliminate the risk of compressed air pipeline fires. An incredibly important factor to consider for the safety of you, your staff and your premises.

Oil-free air compressors can dramatically reduce your energy bills compared to the oil-based counterpart as they require less energy to run which will cut down your environmental impact. Oil-free air compressors do not need increased forces of power when the unit has a drop in the filtration in the downstream pressure, unlike oil-based. Oil-free units can, on average, unload in 2 seconds of your command which only uses around 18% of its full load horsepower.

Of course, all machines come with their downsides and oil-free air compressors are no exception. Oil-free air compressors are known to generate more noise which can be an annoyance and hazard to those using it and those around them.

There is a solution, you can invest in a low-noise air compressor. These reduce noise levels to around 40dB. The lowest safe level is considered 60 dB and anything over 80dB can cause long-term problems with hearing.

With the addition of an acoustic cylinder to contain this noise, opting for a low-noise air compressor is an investment worth making. It is recommended when using any power tool that protective gear is worn to eliminate lasting damage and long-term effects, even with a low-noise machine.

If you were considering purchasing a new air compressor or have simply been doing research on them, you should now have a comprehensive understanding of the benefits an oil-free air compressor possesses.

PSA System for Biogas Upgradation

Pressure swing adsoprtion, also known as PSA, is emerging as the most popular biogas upgradation technology in many parts of the world. A typical PSA system is composed of four vessels in series that are filled with adsorbent media which is capable of removing water vapor, CO2, N2 and O2 from the biogas stream.

During operation, each adsorber operates in an alternating cycle of adsorption, regeneration and pressure buildup. Dry biogas enters the system through the bottom of one of the adsorbers during the first phase of the process. When passing through the vessel, CO2, N2 and O2 are adsorbed onto the surface of the media. The gas leaving the top of the adsorber vessel contains more than 97% CH4

Biogas upgradation through PSA takes place over 4 phases: pressure build-up, adsorption, depressurization and regeneration. The pressure buildup is achieved by equilibrating pressure with a vessel that is at depressurization stage. Final pressure build up occurs by injecting raw biogas. During adsorption, CO2 and/or N2 and/or O2 are adsorbed by the media and the gas exits as CH4.

Depressurization is performed by equalizing with a second pressurizing vessel, and regeneration is achieved at atmospheric pressure, leaving a gas that contains high concentrations of CH4 to be re-circulated. During the regeneration phase, the bed must be regenerated by desorbing (or purging) the adsorbed gases. Purging is accomplished by reducing the pressure in the bed and back-flushing it with some of the concentrated gas product. The gas pressure released from one vessel is used by the other, thus reducing energy consumption and compressor capital costs.

Special adsorption materials are used as a molecular sieve, preferentially adsorbing the target gas species at high pressure. The adsorbent media is usually zeolites (crystalline polymers), carbon molecular sieves or activated carbon. Aside from their ability to discriminate between different gases, adsorbents for PSA systems are usually very porous materials chosen because of their large surface areas.
