COMPRESSOR COMPONENTS
Part
Description
A
Pressure Switch
(AUTO / OFF Switch)
-
In the AUTO position, the compressor shuts off automatically when the tank pressure
reaches the maximum preset pressure. After air is used from the tank and drops to a preset low level, the pressure switch
automatically turns the motor back on. In the OFF position, the compressor will not operate. This switch should be in the OFF
position when connecting or disconnecting the power from the unit.
When the pressure switch turns the motor off you will hear air leaking out of the pressure switch unloader valve for a short
time. This releases the air pressure from the discharge tube and allows the compressor to restart easier.
B
ASME Safety Valve -
This valve automatically releases air if the tank pressure exceeds the preset maximum.
C
Discharge Tube -
This tube carries compressed air from the pump to the check valve. This tube becomes very hot during use.
To avoid the risk of severe burns, never touch the discharge tube.
D
Check Valve -
One-way valve that allows air to enter the tank, but prevents air in the tank from flowing back into the
compressor pump.
E
Belt Guard -
Covers the belt, motor pulley, and flywheel.
F
Drain Valve -
Use this valve to drain moisture from the tank daily to reduce the risk of corrosion.
G
Tank Pressure Gauge -
Indicates the amount of air pressure stored in the tank.
H
Air Filter -
Keeps large particulates out of the air flowing into the compressor.
I
Tank Outlet / Discharge Port -
Air delivery port for transfer of compressed air.
