ABOUT COMPRESSOR DUTY CYCLE:
Compressor Duty Cycle refers to amount of time a compressor can be operated in a given time
period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly
expressed in percentile as:
Compressor On Time/ (Compressor On Time + Off Time)%
As an example, a compressor that is rated for 25% duty cycle means that compressor
can be operated at:
100 PSI @ 72°F for 10 Minutes ON and 30 Minutes OFF
10 Min. On / (10 Min. On + 30 Min. Off) = 10 Min. / 40 Min.
