If i put two identical compressors in serial would the scfm change?
by Jeff Browning
I have 2 - 21 gallon compressors, identical, 125 max working psi, 2.5 running hp, 4.7 scfm @ 90 psi, 5.8 scfm @40 psi.
So i have tank one running a line into tank 2, and check valve in, so flow is one way. Tank 2 produces its own air, as well as what is injected into it from tank 1.
I take air from tank 2 via the pressure regulator valve.
Does my cfm change because i have increased volume of air from 21 to 42?
How is this calculated. I want to run a DA sander rated at 2.8 cfm @90 psi.
I should be good, but also would like to paint with this setup.
