Impact Gun SCFM at 90 PSI

Air demand for a impact gun is 8.0 SCFM at 90 PSI and 10.4 SCFM at 125 PSI.

Impact Gun air demand

Impact Gun air demand is computed deterministically from the parameters encoded in this page's address, so the same inputs always produce the same result and the same OAS-XXXX verification hash.

SCFM at 90 and 125 PSI

SCFM at 90 and 125 PSI is computed deterministically from the parameters encoded in this page's address, so the same inputs always produce the same result and the same OAS-XXXX verification hash.

Compressor sizing and duty cycle

Compressor sizing and duty cycle is computed deterministically from the parameters encoded in this page's address, so the same inputs always produce the same result and the same OAS-XXXX verification hash.

Frequently asked questions

How do I size a receiver tank for a compressor?
Size the receiver so the compressor pumps up in one to five minutes: V = T·(C−D)·Pa / ΔP, where C is compressor output, D is shop demand, Pa is atmospheric pressure and ΔP is the cut-in to cut-out band.
What duty cycle should a shop compressor run at?
Keep the duty cycle at or below 70% so the compressor has recovery time between cycles. Duty cycle is demand divided by compressor output; a value above 70% means the compressor is undersized for the tool load.
Why does tool SCFM demand rise with supply pressure?
Most air tools consume more air at higher supply pressure because the motor runs faster. A 1 in impact wrench draws about 12 SCFM at 90 PSI but 15.6 SCFM at 125 PSI, so size the compressor for the pressure you actually run.
