Duty Cycle; Specifications - Porter-Cable C3101 Instruction Manual

Become familiar with these terms before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSIG: Pounds per square inch gauge; a unit of measure of pressure.
Code Certification: Products that bear one or more of the following marks: UL,
CUL, ETL, CETL, have been evaluated by OSHA certified independent safety
laboratories and meet the applicable Underwriters Laboratories Standards for
Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue
to use your accessory. 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: Circuit carrying electricity from electrical panel to outlet.
This air compressor pump is capable of running continuously. However, to
prolong the life of your air compressor, it is recommended that a 50%-75%
average duty cycle be maintained; that is, the air compressor pump should not
run more than 30-45 minutes in any given hour.
