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.Fill Rates:31" x 10.5" 33" x 12.5" 35" x 12.5" 37" x 12.5" 0 - 30 PSI 4 min. 05 sec. 5 min. 30 sec 6 min. 55 sec. 7 min. 56 sec. 15 - 30 PSI 2 min. 10 sec. 2 min. 50 sec
