Kussmaul Auto Pump HP AD, 091-9HP-AD
Kussmaul Auto Pump HP AD
The Auto Pump HP AD is a permanent split capacitor 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 HP automatically starts to maintain the pressure.
The Auto Pump HP motor is directly coupled to the compressor section eliminating all belts and pulleys assuring long life and reliable operation. A heavy duty, fixed set-point pressure switch starts the compressor when the pressure switch drops below 105 PSI and stops the compressor when 125 PSI is attained. A small pressure gauge indicates the Auto Pump output pressure and helps with installation and troubleshooting.
