Understanding Air tools or pneumatic tools

Air tools or Pneumatic tools are powered by compressed air. Common types of these air-powered you may already know about that are used in the industry include buffers, nailing and stapling guns, grinders, drills, jackhammers, chipping hammers, riveting guns, sanders, and wrenches. In a situation that does not have sufficient space and calls for portability, a pneumatic (air) tool can also be driven by carbon dioxide in a compressed seamless cylinder. This article will enable the readers to understand air tools or pneumatic tools.

Pneumatic tools function by converting compressed to work using a pneumatic motor. From the safety at work standpoint, pneumatic tools are safer to run and maintain, and they have a substantial lifespan compared to electric power tools or battery power tools. There is no risk resulting from sparks, short-circuiting, or even electrocution when using air tools. Air tools have a high power to weight ratio, which means that a smaller and lighter tool can accomplish equivalent weight with electric-driven tools. Finally, pneumatic tools are less likely to get destroyed when jammed or overloaded like their electric or battery-driven counterparts.

There are different types of air tools depending on their applicability. There are sets of air tools that are standard air tools that generally have a shorter lifespan and are commonly less expensive than industrial-grade or professional pneumatic tools. The professional-grade pneumatic tools usually have a longer life span and are more costly than the standard air tools. Most pneumatic tools are to be supplied with compressed air at 4 to 6 bar.

Since Pneumatic tools get their power from air generated by a compressor, it is essential to understand the amount of air required to make the tools work from a compressor. A tool's volume and pressure requirements will dictate the strength of the air compressor needed to power your device.

Understand air compressors for pneumatic tools

Effectively operating a compressed air system — especially for more than a single application — requires that operators maintain a pulse on critical performance indicators, including speed, load size, air pressure, and airflow rate. The latter two measurements, air pressure and flow rate are measured using two distinct metrics: PSI and CFM.

It is essential to understand the difference between PSI and CFM two and what is the nature of the relationship between pressure and rate of flow within a compressed air system? Air from an air compressor is measured in cubic feet per minuted or CFM, while pressure is measured in pounds per square inch (PSI). Pounds per square inch (PSI) is the metric for assessing how many pounds of pressure are exerted on a single square inch of space — 100 psi equates to 100 pounds of force exerted per square inch. The air gauge on an industrial compressor typically displays PSI within the compressed air system.

Cubic feet per minute (CFM) is a measure of volume used to indicate an air compressor's output rate in terms of cubic feet of air per minute of operation. CFM is measured at a given PSI and increases in direct proportion to the horsepower (HP) that is applied. While small, mobile at-home air compressors may deliver around 2 CFM, industrial air compressors with 200 HP can achieve airflow of around 1,000 CFM at 100 PSI.

Pneumatic tools can work endlessly as long as an air compressor is attached to function and continuously deliver the required volume and pressure. On the other hand, air compressors usually have labels with their capacity in gallons, and their output is labeled with their CFM at different pressures. An example is a compressor that is a 26-gallon air compressor that delivers 4.5CFM at 90PSI and 4.0 CFM at 100 PSI. Users of pneumatic tools must read instructions on their tools and ensure their available compressors can power all their tools individually and collectively.

What size of compressor does your air tool require?

As mentioned earlier, CFM means Cubic Feet per Minute, and this is the volume of air an air compressor can pump out per minute.

When you are in the market to buy an air compressor, you must look out for and calculate how much air is needed to power your tool. To figure this out, you need to know how much airflow your tool requires to run. Almost all air tools have specific requirements in regards to air volume and pressure. All pneumatic tools have a tool specification on their nameplate, and please look out for it.

Before making the purchase, you must meet these requirements with your chosen air compressor for the tool to function at its best. The CFM requirement and the tank are the most significant considerations you must take into account when shopping for a compressor. You can find the CFM requirement of your tool from its manual or technical specification, usually on the tool nameplate.

Air tools are also Power tools.

Air-powered tools are generally cheaper than electric tools and are intended to be easily and frequently replaced. Air-powered versions are lighter and smaller than electric tools, but they pack the same (or often higher) amount of punch.

Advantages of pneumatic tools

Pneumatic tools have a lot of advantages than disadvantages, but they come with some disadvantages also. One of the main benefits of pneumatics is the price. Other individual tools powered with batteries and electricity are far more expensive than their pneumatic counterparts. Pneumatic tools also come with safety in wet environments or in places where sparks from electric motors can be dangerous. Pneumatic tools are much lighter in weight, primarily due to the absence of electric motors or bulky battery packs. If you pair an air tool with a suitable air compressor, pneumatic tools can deliver significant amounts of torque and can operate for an incredible amount of productive time. Other air tools such as air spray painters using air from air compressors can also deliver superior results and can effortlessly apply large volumes of coatings to nearly any project, no matter how large.


One of the downside of the pneumatic tool that is a significant disadvantage is the air compressor requirement. The necessity of pneumatic tools attached to a large, heavy air compressor is a limiting factor and significantly reduces portability and effective use of space. Pneumatic tools require more maintenance than electric tools do. The is a need for regular oil air tools to prevent rust and lubricate their inner workings; air-driven tools require regular attention. Air compressors tend to collect moisture from the surrounding air and pass it along to your tools, so it's essential to drain and lubricate your compressor regularly as well. We all know that air contains oxygen which is an oxidizing agent, and this makes the tools susceptible to rusts

Using Pneumatic tools afford users a degree of flexibility. Most consumer-grade air-driven tools use the same 1/4" quick-connect fittings, making it possible to use a single compressor to drive several tools simultaneously. Though investing in an air compressor can seem a lot, and air compressor has some added household value. With the vast array of fittings and adapters available, you can inflate many things from balloons, car tires to an inflatable swimming pool and cleaning delicate equipment.

Pneumatic tools are generally safe and can last for a very long time. So far, no, the elegance brought by its ease of use and safety does not have a replacement. Pneumatic tools can last a lifetime with minimal maintenance. If you want durable tools that can work for a long time, make that choice and speak to our agents for some of the most critical air tools.
