Erm, not really.
The bigger the air compressor receiver the better really. On my 200L SIP you can run air tools for about a minute before it even needs to kick in the motor.
Joe,
I just looked up the specs of the typical SIP offering with 200l receiver. Here are a couple of pertinent lines from that advert:
Piston Displacement: | 13.00CFM (368ltr/min) |
Free Air Delivery (FAD): | 8.50CFM (240ltr/min) |
3HP single phase.
Yes, the tools use is in FAD, not pressure (although they do need the pressure at the tool inlet). The compressor will restart well above the 5, or 6, Bar required for operation of most air tools, so the larger tank is simply a buffer before the pump kicks in again. Tool FAD will determine whether the receiver pressure continues to reduce or steadily gets refilled to cut-out pressure. That chinese (or Italian) rating of 13CFM - meaning only real, actual, truthful production of 8.5CFM says it all really.
That compressor will service tools continuously only if they consume less than 8 1/2 CFM. Typical hype for those that don’t know - bumping up the real output by an advertised 50% more than the truth!
