The motor horsepower usually determines the CFM that the compressor will deliver. A rule of thumb is to figure a compressor will produce 3.5CFM per horsepower. A 5 horsepower compressor will deliver 3.5 X 5=17.5CFM. Remember this is only rule of thumb. Consult the actual specifications on the compressor you plan to purchase.
