How To Increase CFM On Air Compressor (3 Steps To Follow)

Using a specific air tool to increase the CFM of an air compressor is a simple job. However, if the process goes wrong, the CFM of the air compressor will harm your project. As a result, understanding how to boost CFM on air compressors in a safe and efficient manner can save us money while also allowing us to complete the job.

Air compressors are frequently used in conjunction with a range of air tools, such as frame nailers, impact wrenches, and other air tools with varying CFM. Increasing productivity by changing the CFM of an air compressor is possible, but it’s a hazardous operation. Furthermore, using the incorrect procedure might cause harm to the most delicate air compressor capable of filling the tank.

In today’s article, we are glad to introduce you to some detailed instructions and tips on how to increase CFM on air pressure. Let’s get started!

Things You Should Know About Increasing CFM On Air Compressor

Cubic feet per minute (cu ft/min) is the abbreviated form of CFM. It is a measurement of how quickly air enters or exits an area. This is a measurement of the flow or output rate of air coming out of your compressor in compressed air.

This measurement refers to the amount of air a unit can provide at a specific pressure (PSI) in one minute.

Airflow that is too high or too low might cause system failure and even component deterioration. As a result, CFM is critical for selecting a good compressor with the appropriate capacity.

The type and quantity of tools you use will determine how much CFM you require for your air compressor. CFM ratings of 0.1-5 at 70-90 psi are typical for portable air compressors attached to air tools for ordinary usage.

A stationary compressor system for heavy-duty equipment, on the other hand, may require a CFM value of more than 10 at 100-120 psi.

In some cases, you might need to try increasing the air pressure to operate with larger air tools or several air tools at the same time. If not, the current air CFM may not be sufficient.

Two things you must prepare before increasing CFM on the air compressor are:

  • A well functional air compressor.
  • 3 fitting hoses.

How To Increase CFM On Air Compressor (Detailed Instructions)

In such cases, connecting two compressors is an excellent way to increase the CFM of your air compressor. For instance, if you need more than 5 CFM and your compressor’s maximum capacity is 5, you may use this approach to boost the number beyond the machine’s capability.

If you are confused about how to do it, follow the below steps:

1. Connect the tanks with two separate hoses

Firmly insert the female end of the hose into one end of the hose. To do so, you need to use two tools: one to grasp the air hose and the other to grip the fitting. It’s never a good idea to over-tighten it. Wrap the other ends with Teflon tape after attaching the male fitting.

2. Using a third hose, connect the two hoses together

Three different holes should be present in the third one. One of them will function as the output hole, while the others will function as the input hole.

3. Connect the tool to the output hole of the third hole

This is the final step, and once you finish it, your air compressor is ready to increase CFM.

If most of your tasks require a higher CFM rating, we recommend choosing a higher CFM air compressor. Conversely, you can acquire a lower CFM compressor to connect with your existing one if most of your work requires low CFM, but you occasionally need greater CFM.


Does CFM go up with PSI?

The PSI changes as the CFM changes. CFM increases when the PSI output is reduced. A higher CFM compressor can supply more air and better suit heavy applications like running air wrenches and framing nail guns.

Storage tank sizes are measured in gallons by compressor manufacturers. For many applications, such as airbrushing and running brad nailers or nail guns, smaller tanks (about 4 to 6 gallons) are suitable. More compressed air is stored in larger tanks at greater pressures. They’re best for jobs that demand a lot of air movement, including automotive repair or renovation projects.

Is higher CFM better for air compressors?

Yes, but it’s not always the case. The tanks on the compressors we picked range from 1 to 6 gallons. A bigger tank stores more air, allowing you to utilize more before the pressure lowers and the motor starts to replenish the tank. That way, you won’t have to stop working while the compressor refills the tank. However, keep in mind that when your job needs a significant air volume, a huge tank is no replacement for appropriate CFM.

Can an air compressor tank explode?

An air receiver tank containing pressurized air has the potential to explode. However, it’s incredibly unusual, and it usually happens when operators neglect their air receiver tank.

Corrosion is the primary reason for air compressor tank explosions. When operators fail to drain water that accumulates in their tanks, the water can create corrosion, weakening the tank until compressed air is used to blow it apart.

Poorly constructed items or manufacturing flaws are the second most prevalent cause of an air tank explosion. An air receiver tank, for example, without a suitable pressure release valve, may get over-pressurized and explode as a result. These sorts of explosions should be avoided by working with a professional air receiver tank manufacturer.


You have made it to the end of our article on how to increase CFM on air compressors. Hopefully, you no longer have any concerns about raising the air compressor’s CFM number. The method for increasing CFM on air compressors that have been discussed is simple, and we suggest you should give it a try.

However, it would be preferable if you purchased an air compressor in accordance with the project specifications. You may avoid the hassle of changing the air compressor’s CFM value this way.
