Duty Cycle Explained


This is a reference page to what "duty cycle" refers to when speaking about air compressors. Duty cycle refers to the amount of time a compressor can be operated in a given period, at 100 PSI, and at a standard temperature of 72 degrees F. Duty cycle is commonly expressed in percentage format as: Compressor on time DIVIDED BY (on time + on time) = Duty Cycle Percentage.

Below is a Duty Cycle Reference Chart. Please keep in mind when looking at the chart that your compressor will not always run 10 or 15 minutes straight. Compressor fill or recover pressure in tank then shut off. Also keep in mind that compressors in the same series fill faster with lower duty cycle percentage. It is like the tortoise and the hare. The tortoise is 100% duty, run slower but doesn't need to stop to rest. This will make more sense when you look at the compressors and compare fill times.

DUTY CYCLE REFERENCE CHART(Duty Cycle: 100 PSI @ 72 Degree F.)
9% Duty Cycle: 3 Min. Run Time / 30 Min. Rest Time
10% Duty Cycle: 3 Min. Run Time / 27 Min. Rest Time
15% Duty Cycle: 6 Min. Run Time / 34 Min. Rest Time
20% Duty Cycle: 8 Min. Run Time / 32 Min. Rest Time
25% Duty Cycle: 10 Min. Run Time / 30 Min. Rest Time
30% Duty Cycle: 13 Min. Run Time / 30 Min. Rest Time
33% Duty Cycle: 15 Min. Run Time / 30 Min. Rest Time
40% Duty Cycle: 20 Min. Run Time / 30 Min. Rest Time
100% Duty Cycle: Continuous Duty @ 100 PSI @ 72 Degree F.
