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

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.
