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 = 25% duty cycle.
