GLOSSARY OF TERMS

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.
Belt Guard
Protects the operator from coming in contact with the belt
and rotating pulleys.
Cut-In Pressure
The low pressure at which the engine speed will automatically
increase to full speed.
Cut-Off Pressure
The high pressure at which the engine speed will automatically
decrease to idle speed.
NPT (National Pipe Thread)
A seal thread tape must be used to provide a leak-free seal
on pipe threaded connections.
Pressure Regulator Knob
Regulates the outgoing pressure from the air outlet to the
tool. It is possible to increase or decrease the pressure at
the outlet by adjusting this control knob.
Pressure Unloader
Automatically controls the speed of the compressor's engine.
The engine runs at idle speed when the cut-off pressure in
the tank is reached and switches the engine to full speed
once the 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.
Quick Connect Couplers
The 1/4 in. quick connect couplers allow the operator to
easily attach air hoses to the compressor.
Outlet pressure gauge
Displays the current line pressure. Line pressure is adjusted
by rotating the pressure regulator knob.
Safety valve
Prevents air pressure in the air tank from rising over a
predetermined limit.
SCFM (Standard Cubic Feet Per Minute) or CFM (Cubic
Feet Per Minute)
A unit of measure of air delivery.
Tank Pressure Gauge
Indicates the pressure in the air tank.
