Help in sizing a compressor
by Brian
I need 72 CFM @ a constant 80 psi. What size compressor will I need please. Bill says... Brian, the rough rule of thumb is you will get about 4 CMF of compressed air at 90 PSI for each HP of motor size. The only way you can be sure that a specific compressor will give you the flow you require, is to ask that question of the manufacturer's rep. Each compressor is different, and if your flow and pressure is critical to your operation, ask the supplier. I think you will be looking for around a 20 HP compressor. Cheers, Bill
