compression is completed. They are one of
the most effective means of removing
moisture from compressed air.
Air Receivers - tanks into which the
compressed air is discharged from the air
compressor. Receivers help to eliminate
pulsations in the discharge line and also act
as storage capacity during intervals when the
demand increases.
Check Valve - Ensures the air flows in one
direction.
Discharge Pressure - This is the absolute
pressure of the air at outlet (delivery) of a
compressor.
Free Air Delivery (FAD) - Free air delivery is
the volume of air delivered under the
conditions of temperature and pressure
existing at the compressor intake. This is
generally taken as 1.0332 kg/cm square abs
& 15 degree Centigrade.
Inlet Pressure - This is the absolute
pressure of the air at inlet (suction) to a
compressor.
Line Pressure Gauge - Reads amount of
pressure in the air hose, which supplies the
tool with air.
PSIG - pounds per square inch gauge
Rotary Air Compressors - those which
utilize two inter-meshing helical rotors to trap
a volume of air, then compress it to a higher
pressure.
Single Stage Air Compressors - those in
which compression from initial to final
pressure is complete in a single step or
stage.
Tank - Holds the compressed air until used
by an air tool or for some other purpose.
Tank Pressure Gauge - Indicates amount of
pressure in tank.
