  • Wire terminal ends to simplify installation (ring ground terminal, spade positive lead terminal)

Duty Cycle Reference Chart:

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 %.

Please 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.

One Hour Duty Cycle (100 PSI @ 72° F)Minutes On / Minutes Off
9% Duty Cycle5 Min. On / 55 Min. Off
10% Duty Cycle6 Min. On / 54 Min. Off
15% Duty Cycle9 Min. On / 51 Min. Off
20% Duty Cycle12 Min. On / 48 Min. Off
25% Duty Cycle15 Min. On / 45 Min. Off
30% Duty Cycle18 Min. On / 42 Min. Off
33% Duty Cycle20 Min. On / 40 Min. Off
50% Duty Cycle30 Min. On / 30 Min. Off
100% Duty Cycle1 Hour Run Time

All VIAIR compressors are tested at an ambient temperature of 72 degrees Fahrenheit, with a supply voltage of 13.8 volts for 12-volt models & 28 volts for 24-volt models. It is recommended that you always operate VIAIR compressors with charging voltage or maintain recommended supply voltage for best performance.
