Air Compressors has multiple usages. Its importance among air tools can’t be denied.

It requires a certain CFM level to operate properly.

Different air tools require different CFM requirements. You shouldn’t expect these requirements from a single compressor. You have to modify it for higher CFM output.

To do that we’ll discuss three actionable ways.


What is CFM?

CFM stands for cubic feet per minute. Which it’s the measurement of the speed of air that is getting sucked by an air compressor.

CFM is measured by the size of the tank of the air compressor and the size of the pump’s cylinder and what’s peed the pump is operating.

CFM is directly connected to the application of the air compressor. For different air tools, you need different CFM.

Moreover, CFM is a vital factor in your air compressor or any other air tool, and without it, it wouldn’t work as the compressor won’t be able to generate any pressure without having air going it. Therefore the tools won’t be able to work.


How to Increase CFM on Air Compressor

1- Hook Two Compressors Together

If you want to increase CFM on your air compressor, you will need to purchase another air compressor and hook them together.

How can you connect two compressors? Follow these steps:

  • Connect the tanks of two compressors with two different hoses.
  • Get another hose and connect the two hoses to the third one.
  • Make sure that the third hose has three holes, two holes can be used as inputs, and the third one can be used as output.
  • Connect the third hole in your tool as output, and you’re done.

If you want it to increase more than the maximum capacity of CFM, then you’ll extra help from another machine.

These steps will give your compressor an extra boost of CFM to increase the capacity of CFM in one air compressor.

On the other hand, this way of increasing CFM has disadvantages as it might take more time to fill up the compressors’ tanks possibly will reach double the time.
In addition to that, it could also make the tool you’re using not work properly. Not only this but also the overheating issues may occur at any time.


2- Decreasing the Pressure to Increase CFM

Every air compressor has a certain power level; this power level depends on the CFM and pressure. To keep the equation stable and the power constant, if you increase CFM, you have to decrease the pressure.

Keep in mind that you can’t operate a compressor beyond its power limit. As if you decrease the pressure in the tank, the CFM of the compressor will increase, and to keep the balance, you have to use a regulator.

The regulator makes the air flows in the tank slowly leading to form lower pressure therein which will increase the CFM in your compressor.

3- Allow the Compressor With More Time

This way is to give your compressor a slight boost of CFM.

Allowing the compressor more time is an inexpensive way to enhance the compressor CFM that will eventually give the compressor time to work on compressed air. Consequently, letting the compressor to maintain the tank pressure up.

Moreover, This process is simple.

All you have to do is to dial down the regulator at its lowest degree. Don’t go to the lowest settings at once but go down gradually with control.

This will run the compressor motor for a longer time which will make the density of the compressed air higher. Consequently, increasing the CFM.

To sum up, this process will enhance the compressor’s lifetime, but if you need more increase of the CFM, this won’t be the perfect way to.



These ways of increasing the CFM in an air compressor will make the air compressor likely to run for a longer period of time.

Be aware that these methods require experience to be done if you’re new to this use the help of an expert.

To sum up, Get an air compressor matching the rate of CFM you require so you don’t face the trouble of increasing the CFM.
