How to Increase CFM on an Air Compressor?

Everyone wants the excellent air flowing, don’t they? So, air compressors are a pretty standard appliance nowadays. But to get it all the time, you will need to know how to increase CFM on the air compressor?

Talking about air compressors, it will be a crime not to speak about CFM. If you are familiar with air compressors, then you must know what CFM is. But don’t worry if you have no idea about it; most people are clueless regarding it. CFM is the measure of the air which an air compressor can compress, and it stands for cubic feet per minute.

Now, let’s get back to the previous question. Below you must have realized that CFM is an important concept, not only theoretically but also practically. So, let’s see more about this in the next section.

How to Increase CFM on an Air Compressor?

Before knowing how to increase CFM on an air compressor, don’t you think we should understand why it is necessary? And is higher CFM better? Let’s see!

You know that the CFM is the measure of compressed airflow. So, yeah l it is good to have higher CFM. For example, 0.5 to 1 CFM is good for small post-table compressors, while large ones should give at least a solid 10.

As a rule of thumb, one CFM square foot should be the bare minimum, and anything more than that is considered extra good.

There are many ways to increase CFM on a compressor. You can either decrease the pressure or increase the area of the compressor to increase the CFM. Alternatively, you can use another compressor in combination with your first one to get the desired results. 

Let’s see some of the methods in the next section.

Methods to Increase CFM on Air Compressor

As mentioned before, we can use various techniques to increase the CFM on the air compressor. A few of these are worth mentioning: 

Decrease the pressure on your compressor

The CFM companies’ mark is generally for low-pressure conditions, and you usually won’t get the highest range. In general, compressors require moderate pressure for functioning well but give more output at lower pressure. So, you should try to keep the pressure as low as possible.

Add another compressor

You can add another compressor of the same model to double your results. Alternatively, you can also connect to different types of compressors together, but that will be a tedious process.

And another air receiver tank

Your compressor already comes with one air receiver tank. By adding another, you can double the output as it will be required to fill both the tanks.

Increase the pump size

This option is suitable to increase the CFM for the long term. However, you should upgrade your pump and a new pump of larger size to ensure better facilities.


CFM is an essential concept for air compressors and people dealing with them. If you are a compressor expert, then you surely know how to deal with all this mess. But most people don’t have any idea regarding this matter. So, it is recommended that you read the instructions given in your manual. and even if after leading you don’t get any idea or clue about how to deal with this, don’t freak out. You can always call a professional to handle things for you.

But, how to increase CFM on the air compressor? This is not too hard to do, but it can be a daunting task if you have never done this before. If you are 100% sure that you can’t do it yourself, you should get some help. 

Increasing the CFM air compressor will help you get cooler air and a better environment in your house, office, or the place the compressor is installed.


How to calculate CFM on an air compressor?

Calculating your air compressor, CFM, isn’t as easy as said. You will surely need to know a little about physics to be able to do this. So, good luck if you skipped your classes. Sometimes they teach things that may be useful.

An easier way to calculate CFM is to use an airflow. For accurate readings, install the receiver tank near the airflow, and take the measurements of volume and pressure by plugging the device. If you can’t figure it out yourself, then take some help.

Is higher CFM better?

Most people have this confusion about whether the CFM should be high or low for a good compressor. Here we are trying to increase the CFM, so it is evident that the higher, the better.

Higher CFM will make it easy for your compressor to compress air and put it out constantly. Plus, it also helps to maintain homeostasis.
