How does this work? Well, if you connect two compressors having 5 CFM and 3 CFM, then you can get 8 CFM at once. Here you will be connecting two compressors for more CFM. In this case, there is another method that you can follow. What if your compressor has a maximum limit of 5 CFM but you need more than that. The previous method won’t be able to provide CFM higher than the maximum limit of your compressor.

Method 2: Connecting Two Compressors to Increase CFM But this is safe for your compressor and won’t damage the compressor anyhow. If you follow this method, you can only reach a certain limit. So this is one way to increase CFM on an air compressor. Now, when you decrease the pressure from 90 PSI there will be an air output of more than 5 CFM. What does this mean? It means if the pressure reaches to 90 PSI then the compressor will provide an air output volume of 5 CFM. Let’s say you have a compressor with a rating of 5 CFM at 90 PSI. This lower pressure then allows you to have a higher CFM.Īn example will clear this out for you. When you dial the regulator down, air flows into the tank slowly and builds a lower pressure inside. And to do so, you need to dial down the regulator. So if you can build less pressure in the tank, then the CFM of your compressor will increase. However, you cannot operate an air compressor beyond its power limit.

To keep this constant power, if you increase the CFM you have to lower down the pressure. Mathematically speaking, Power = Pressure x (Volume/Time). This power depends on the pressure and the CFM. This pressure then helps the air to go out at a certain rate which we are referring to as CFM.Įvery air compressor has a certain power level. These are – Method 1: Decreasing the Pressure to Increase CFMĪ compressor first takes air inside. However, I found some ways that you can follow to make your compressor a high CFM compressor. Usually, an air compressor is built with a specific CFM rating for a specific pressure (Like, 2.6 CFM at 90 PSI). Credit: How to Increase CFM on Air Compressor For different air tools you need different CFM, and so you have to get an air compressor according to that CFM level. If a compressor has a rating of 8 CFM, this means 8 cubic feet of air will come out in one minute, from that compressor.ĬFM is directly connected to the application of the compressor. In a simple term, CFM is the flow rate of the volume of air that comes out of an air compressor.
