1-5. PURPOSE, CAPABILITIES AND FEATURES
Purpose of the Air Compressor Set
An electric motor driven air compressor for general shop use.
Capabilities and Features
2-stage compressor provides compressed air at 5 cfm and 175 psi.
Electric motor driven.
Motor starter with melting alloy relay protects motor against overload.
Pressure switch provides for automatic compressor cut in at 160 psi and cut out at 180 psi, and
automatic unloading for model 20-911.
Air discharge system with inflator gage can be used to directly inflate tires to proper pressure.
Tank mounted pressure gage gives constant reading of air pressure in tank.
1-6. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
1. PRESSURE SWITCH. Diaphragm senses pressure and opens and closes switch contacts. Cutout pressure and
pressure difference between cut in and cutout are adjustable with 2 screws.
2. MOTOR STARTER. Contacts are magnetically clod when power is applied. Also contains a melting alloy relay which
opens the circuit when a current overload is sensed.
3. BELT GUARD. Steel mesh and sheet metal construction protects belts and personnel.
