BASIC AIR COMPRESSOR COMPONENTS
Oil free air compressors are factory lubricated for life and do not require any oil.
The basic components of the air compressor are the electric motor, pump,
pressure switch and tank.
The electric motor (A) powers the pump. The electric
motor is equipped with an overload protector and an
automatic reset. If the motor becomes overheated,
the overload protector will shut it down to prevent
damage to the motor. When the motor sufficiently
cools, it will automatically reset.
The pump (A) compresses the air and discharges it
into the tank.
The tank (B) stores the compressed air.
The pressure switch (C) shuts down the motor when the
air pressure in the tank reaches the cut-out pressure. As
compressed air is used and the pressure level in the tank
drops to the cut-in pressure, the pressure switch restarts
the motor automatically, without warning and the pump
resumes compressing air.
COMPRESSOR CONTROLS
A. AUTO/OFF SWITCH
This switch turns on the compressor. It is operated manually, but when in
the AUTO position, it allows the compressor to start up or shut down
automatically, without warning, upon air demand. ALWAYS set this switch to
OFF when the compressor is not being used, and before unplugging the
compressor.
B. PRESSURE RELIEF VALVE
The air compressor is equipped with a pressure relief valve that is designed to
discharge tank pressure at a predetermined setting when a systems failure
occurs. Check the pressure valve periodically by pulling on the ring only when
