How To Increase CFM On Air Compressor

How To Increase CFM On Air CompressorIn case you’re a carpenter or mechanic or into some other sort of handmade work, air devices are your everyday partners!


As you probably are aware, air instruments accompany an exceptionally strict necessity of an air compressor.

Air compressors are helpful with a vast range of uses.

For example, you can utilize them to paint your divider, pump a punctured tire, or even utilize a pneumatic nail.

Most of the air compressors online will be extraordinary; you can buy compact ones or fixed ones.

Every one of them presumably has an alternate greatest PSI, so a few instruments probably won’t be appropriate for certain blowers, while others might be.

Accordingly, it’s essential to know precisely what you need to utilize it for before you feel free to buy it.

What is CFM?

CFM (cubic foot per meter) is a significant factor for any air compressor.

Without it, it would not generally work properly as there will be no air going inside the compressor to create any pressure for making tools to work.

You ought to never believe that this angle isn’t significant because when you’re choosing what air compressor you should buy, this is unquestionably a component that you ought to be taking a gander at.

This is in such a case that an air compressor has a higher CFM, it implies that it can create more air for your instrument, and this implies on the off chance that you need a difficult task finished, at that point, it’s ideal for getting one that has a higher CFM.

Methods To Increase Air Compressors CFM

In this article, two methods are discussed to increase CFM in an air compressor.

Both the techniques apply to any of the compressors you have.

Hence, you can follow any of the techniques you feel better at according to your convenience.

The First Method Is To Increase CFM By Decreasing PSI:

Before applying this strategy, you must know the connection between weight and CFM numerically.

We realize that power = volume/time, where volume/time demonstrates pressure here.

That implies you have to drop down the weight if you need to build the CFM.

Each air instrument has a limit to reducing the pressure to work.

Using that limit, set the dial and let it down to that absolute bottom to boost the CFM.

Let me disclose to you how it happens.

Putting the regulator down continues to slow down the airflow in the tank and permits the compressor to continue filling the tank for quite a while.

This is because the higher the pressure, the higher the stream rate that the air instrument requests, and the harder it is for the compressor to satisfy the demand of the air apparatus.

At the point when the pressure is kept at the conceivable absolute bottom, the compressor can stay aware of the pressure inside it.

For understanding in a clear way, suppose you have an air device working at 150 PSI, and you will let it down to 90 PSI.

When the air apparatus works at 150 PSI, it requests more air contrasted with 90 PSI.

Thus, the pressure in the tank drops rapidly, and the compressor can’t siphon air into the tank as much as the device requires.

Then again, when you let down the pressure to 90 PSI from 150 PSI, there is enough pressure in the tank, and it will require some time for the pressure to drop.

This gives more opportunity for the compressor to keep the pneumatic force up in the tank.

Truly, this is a powerful method to tackle your concern.

Yet, the CFM of your compressor is as yet the same as you set the regulator.

The Second Method Is Combining Two Compressors For Higher CFM:

If you would like to expand the CFM on an air compressor, you should presumably buy another air compressor and snare them together, or something comparable.

This is in such a case that you need it to build more than the maximum limit available so, you will require extra assistance from an alternate machine.

For such a scenario, you require three hoses – two of which are utilized for interfacing the two compressors, and the third one is for associating those two.

The third one ought to have three openings, two for inputs, and another for yield. To finish the cycle, you have to interface the yield with your air instrument.

There is one disadvantage about utilizing this strategy, and that is the way that it might take more time to fill both of the tanks with air, and given this, it is probably going to overheat and may even prompt other issues as well.

Two things should be considered while increasing the CFM of the compressor.

Check Valves

There must be some check valves in the line from every compressor with the goal that air can’t stream back to the compressor. However, it can stream away from the compressor.

Pressure Adjustment

The two compressors ought to have a comparative measure of pressure. This will guarantee a similar measure of work done by everyone to satisfy the air need of the air instrument.

If there is an excessive contrast between two weight switches of the two compressors, one compressor may need to do practically all the works.

This will cause substantially more successive stops and starts of that one. Thus, it is critical to change the pressure of the two compressors.


Hence, there are ways that you can increase the CFM of the air compressor, and this will imply that the air compressor is probably going to run for a more extended period if you choose to use certain methods.

The process of increasing the CFM of the air compressor requires expertise to execute. Especially when you are new to this, then there are high chances that you take the wrong steps.

It would be advised that to avoid mistakes, take an expert’s help, or first learn how to do it.
