Rebuilding Kit for
Auto Pump Air Compressor system is a 120 volt 60 Hz shaded pole A.C.
motor operating a single cylinder air compressor designed specifically
for installation on vehicles with air brakes . During long idle periods
of the vehicle when even the slightest seepage can cause an air brake
system pressure to drop below the brake lockup pressure, the Auto Pump
automatically starts to maintain the pressure. The Auto Pump motor is
directly coupled to the compressor section eliminating all belts and
pulleys and assuring long life and reliable operation. A heavy duty
pressure switch is adjusted to start the compressor when the system
pressure drops below 70 psi and stops the compressor when 90 psi is
attained. The start up pressure is field adjustable - the pressure
differential between start up and stopping is fixed. The Auto Pump
requires no routine maintenance.
