BASIC AIR COMPRESSOR COMPONENTS

Oilless 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, control panel and tank.
The electric motor 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 restart.
Air Filter
Porous element contained within a metal or plastic housing
attached to the compressor cylinder head which removes
impurity from the intake air of the compressor.
Air Tank
Cylindrical component which contains the compressed air.
Check Valve
Device that prevents compressed air from flowing back from the
air tank to the compressor pump.
Cut-In Pressure
The low pressure at which the motor will automatically restart.
Cut-Off Pressure
The high pressure at which the motor will automatically shut off.
Electric Motor
Device which provides the rotational force necessary to operate
the compressor pump.
Manual On/Off Switch
Control which turns the air compressor on or off. The pressure
switch will not automatically start and control the compressor
unless the manual On/Off Switch is in the ON ( l ) position.
NPT (National Pipe Thread)
A seal thread tape must be used to provide a leak-free seal on
pipe threaded connections.

OVERVIEW

The pump compresses the air and discharges it into the tank.
The tank stores the compressed air.
The control panel of the compressor consists of the ON/OFF
button (A) and of the pressure regulator knob (B).
As compressed air is used and the pressure level in the
tank drops to the cut-in pressure, the control board restarts the
motor automatically, without warning, and the pump resumes
compressing air. The pressure regulator shuts down the motor
when the air pressure in the tank reaches the cut-out pressure.

GLOSSARY OF TERMS

Pressure Regulator
Automatically controls the on/off cycling of the compressor.
It stops the compressor when the cut-off pressure in the tank is
reached and starts the compressor when the air pressure drops
below the cut-in pressure.
PSI (Pounds Per Square Inch)
Measurement of the pressure exerted by the force of the
air. The actual PSI is measured by a pressure gauge on the
compressor.
Pump
Produces the compressed air with a reciprocating piston
contained within the cylinder.
Safety Valve
Prevents air pressure in the air tank from rising over a
predetermined limit.
SCFM (Standard Cubic Feet Per Minute)
A unit of measure of air delivery.
Tank Pressure Gauge
Indicates the pressure in the air tank.
Thermal Overload Switch
Automatically shuts off the compressor if the temperature of the
electric motor exceeds a predetermined limit.
