I want to increase CFM from 23 to 30

by David

I have an existing 7.5 hp Bel-air with a 30 cfm dryer and filter. I am adding a piece of equipment that is 12.2 cfm at 90 psi and I am currently using 15 cfm of the existing Bel-air unit. How can I increase cfm without changing out what I currently have? Would a storage tank at one of the pieces of equipment accomplish this?

Increase CFM from
by: Bill

You really cannot increase the output of an air compressor.

You can, however, increase the amount of "pre-compressed" air - as you point out - by using another tank.

The trade off is that the multi-tanks will now take longer to fill to compressor cut out, and that could mean maintenance issues for the motor and pump of the compressor.
