How Do You Calculate The CFM Of An Air Compressor?
CFM stands for cubic feet per minute. Oftentimes the true rate of an air compressor is misrepresented by manufacturers. Because of this, the only way to determine the real CFM of your air compressor is to test it yourself. Don’t be fooled by false advertising any longer–follow these steps and know how much air you’re really pumping. Determine the volume of your air compressor tank in gallons. This should be clearly marked on the tank itself by the manufacturer. Divide the tank volume by 7.48 (7.48 equals the number of gallons in one cubic foot.) The number that you get after the division is the tank volume expressed in cubic feet. Release the air from your compressor. Begin refilling the compressor with air. Record the amount of time that it takes to refill the tank while paying close attention to the compressor’s tank gauge. You will need to record the psig (pounds per square inch) at two separate times in the refill process: once at the moment the compressor kicks in and once at the
