GlOSSARY
CFm:
Cubic feet per minute.
SCFm:
Standard cubic feet per minute; a unit of measure of air delivery.
PSI:
Pounds per square inch; a unit of measure of pressure.

CuT-IN PreSSure:
While the motor is off, air tank pressure drops when accessory is used.
When the tank pressure drops to a certain low level the motor will restart automatically. The
low pressure at which the motor automatically restarts is called cut-in pressure.
CuT-OuT PreSSure:
When an air compressor is turned on and begins to run, air pressure in
the air tank begins to build. It builds to a certain high pressure before the motor automatically
shuts off, protecting your air tank from pressure higher than its capacity. The high pressure at
which the motor shuts off is called cut-out pressure.
BraNCH CIrCuIT:
The circuit carrying electricity from electrical panel to outlet.
duTy CyCle:
For proper operation of your air compressor, it is recommended that a 50% duty
cycle be maintained; that is, the air compressor should not run more that 5 minutes in any 10
minute period.
