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.
ASME:
American Society of Mechanical Engineers; made, tested, inspected, and
registered to meet the standards of ASME.
Cut-In Pressure:
While the motor is off, air tank pressure drops as you continue to
use your accessory or air tool. 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 you turn on your air compressor and it 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.”
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.
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.

connected to a circuit protected by fuses, use dual element time delay fuses.
