VIAIR Corporation

Standard Compressor Features:







Standard Specification Testing:

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.

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.
