How Does It Work?
AirPrime
utilizes air supplied from the chassis air brake
compressor to operate the fire pump primer� This is
proven to be far more efficient and reliable than electric
motor driven rotary vane primers�
AirPrime
virtually eliminates the impact load on the
electrical system improving vehicle reliability�
AirPrime
also improves performance in the elapsed time
for establishing water supply resulting in improved fire
ground operations and safety�
Auto Prime
Move Switch to the upper position� The
Green LED light will illuminate� The primer will activate
when the OK TO PUMP light is ON and the Pump
Pressure is below 20 PSIG�
The Auto Mode only operates when the fire pump is
engaged�
AirPrime
Primers can be used for both New and Retro-Fit installations. In Retro-Fit scenarios,
AirPrime
may be used to augment the
existing primer or as a complete replacement. Automatic
AirPrime
models provide instant re-priming of the pump when required.
An existing rotary vane primer can be upgraded to an Automatic Primer by adding a single location Auto
