COMPRESSOR APPLICATION GUIDE:

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 

sufficient 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.
