Getting To Know Your Compressor (Continued)
GloSSARy of teRmS
ASME Safety Valve: A safety valve that automatically releases
the air if the air receiver (tank) pressure exceeds the preset
maximum�
Regulator Knob: This knob controls the outlet air pressure�
Turning the knob clockwise increases air pressure at the outlet�
Turning counterclockwise will lower air pressure at the outlet�
Fully counterclockwise will shut off the flow of air completely�

Tank Pressure Gauge: Indicates tank pressure in psi� Gauge
shows pressure in air receiver indicating compressor is building
pressure properly�
Outlet Pressure Gauge: This gauge shows air pressure at outlet�
Air pressure is measured in pounds per square inch (PSI)� Most
tools have maximum pressure ratings� Be sure this gauge reads
ZERO before changing air tools or disconnecting hose from
outlet� It is regulated by the regulator knob�
Cut-in/Cut-off Pressure: Specific psi at which a compressor
starts and stops while refilling the air tank�
Belt Guard: The belt guard encloses the pulleys and drive belt�
It protects the user from moving parts and directs cooling air to
the compressor pump�
Air Filter: The air filter keeps dirt and debris from entering the
compressor pump and reduces compressor noise�
Oil Sight Glass: The oil sight glass shows the oil level in the
compressor pump�

Handles: Used to move the compressor�
Tank Drain Valve: The tank drain valve allows moisture to be
removed from the tank�
NOTE: Each tank has its own tank drain valve�
Unloader: The unloader controls the engine rpm� When loaded,
the engine will run at maximum operating speed and air will
enter the tank� When unloaded, the engine will slow to an idle
and air will vent to atmosphere�
Air Storage Tanks: The tanks store air for later use�
Air Outlet Fittings: 3/8 inch universal-style quick connect
fittings allows rapid tool changes�
PSI (Pounds per Square Inch): Measurement of the pressure
exerted by the force of the air� The actual psi output is measured
by a pressure gauge on the compressor�
SCFM (Standard Cubic Feet per Minute): Sometimes called
CFM (Cubic Feet per Minute)� Measurement of air volume
delivered by the compressor�
Air Delivery: A combination of psi and SCFM� The air delivery
required by a tool is stated as (number) SCFM at (number) psi�
The combination of these figures determines what size unit is
needed�
Air Tank Capacity: The volume of air stored in the tank and
available for immediate use� A large tank allows the intermittent
use of an air tool with an air requirement higher than the
compressor's rated delivery�
