When it comes to understanding compressed air systems, it is important to distinguish between CFM (cubic feet per minute) and PSI (pounds per square inch) as they represent different aspects of air pressure and flow.

PSI (Pounds per Square Inch):

PSI refers to the measure of pressure exerted by the compressed air. It indicates the force with which the air is delivered.For example, pneumatic tools like impact wrenches or paint sprayers often require a certain PSI range to function optimally

CFM (Cubic Feet per Minute):

CFM, on the other hand, represents the volume or flow rate of the compressed air. It indicates how much air is being delivered or consumed during a specific period. while PSI measures the pressure of the compressed air, CFM indicates the air volume or flow rate. Both factors are important to consider when selecting and operating compressed air systems to ensure proper tool performance and system efficiency.
