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
%.

NOTE:Allcompressors,regardlessofrateddutycycle,requiresufcientresttimeinbetweencycles
toallowforpartialorcompleteheatdissipation.Heatdissipationratesmayvarydependingon
ambient temperatures and operating conditions.
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.
