GLOSSARY
DUTY CYCLE
Accessories for this unit are available at the store the unit was purchased.
ACCESSORIES
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.
