Duty Cycle; Specifications - Porter-Cable C3151 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.
Porter-Cable air compressors should be operated on not more than a 50%
duty cycle. This means an air compressor that pumps air more than 50% of
one hour is considered misuse, because the air compressor is undersized for
the required air demand. Maximum compressor pumping time per hour is 30
minutes.
