Air Filter
Porous element contained within a metal or plastic
housing attached to the compressor cylinder head
which removes impurities from the intake air of the
compressor.
Air Tank
Cylindrical component which contains the
compressed air.
Check Valve
Device which prevents compressed air from
owing back from the air tank to the compressor
pump.
Electric Motor
Device which provides the rotational force
necessary to operate the compressor pump.
Pressure Gauge
Device which shows the tank or regulated
pressure of the compressed air.
Pressure Switch
Device which automatically controls the on/o
cycling of the compressor. It stops the compressor
when the cut-o 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 air. The actual psi is measured by a pressure
gauge on the compressor.
Pump
Device which produces the compressed air with a
reciprocating piston contained within a cylinder.
Safety Valve
Device which prevents air pressure in the air tank
from rising over a predetermined limit.
Thermal Overload Switch
Device, integrated into the electric motor winding,
which automatically “shuts o” the compressor if
the temperature of the electric motor exceeds a
predetermined limit.
Tank Drain Valve
Valve located at the bottom of the air tank,
provided to drain any condensation build-up. Tank
should be drained daily after use.
