ABOUT COMPRESSOR DUTY CYCLE:
Duty cycle refers to the amount of time a compressor can beoperated in a given time period at
100 PSI, and a standard ambient temperature of 72° F. It is commonly expressed in percentage
format: Compressor on time ÷ (on time + off time) = Duty Cycle %.

9% 5 Min. On / 55 Min. Off
10% 6 Min. On / 54 Min. Off
15% 9 Min. On / 51 Min. Off
20% 12 Min. On / 48 Min. Off
25% 15 Min. On / 45 Min. Off
30% 18 Min. On / 42 Min. Off
33% 19 Min. On / 41 Min. Off
50% 30 Min. On / 30 Min. Off
100% 1 Hour Run Time
ABOUT RATED WORKING PRESSURE:
To ensure trouble free service life of your compressor, always operate compressor within rated
working pressure of the compressor. Never use a pressure switch with a higher cut-off pressure
than compressor’s rated working pressure.
