How to Calculate Compressor CFM

Compressor CFM (cubic feet per minute) is a measure of the volume of air that a compressor can deliver. Here is a simple method for calculating compressor CFM:

  • Determine the pressure drop: The first step is to determine the pressure drop across the system. This is the difference between the inlet pressure and the outlet pressure of the system. The pressure drop can be calculated using the following formula: Pressure Drop = Outlet Pressure – Inlet Pressure
  • Determine the air density: The air density can be calculated using the following formula: Air Density = Pressure / (Specific Gas Constant * Temperature)
  • Determine the CFM: Once you have determined the pressure drop and air density, you can calculate the CFM using the following formula: CFM = (Air Flow Rate) / (Air Density)

Keep in mind that this is just a basic method for calculating compressor CFM and may not be suitable for all applications. It is always a good idea to consult with a professional or refer to the manufacturer’s guidelines when selecting a compressor to ensure that it meets the specific needs of your system
