CFM: Cubic feet per minute.
SCFM: Standard cubic feet per min-
ute; 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 auto-
matically. 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 auto-
matically 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 elec-
tricity 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.
