GLOSSARY
CFM
: Cubic feet per minute.
SCFM:
Standard cubic feet per minute; a unit of measure of air
delivery.
PSI:
Pounds per square inch; a unit of measure of pressure.
kPa (kilopascal):
Metric pressure measurement. 1 kilopascal
equal 1000 pascals.
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
when accessory is used. 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:
The circuit carrying electricity from electrical
panel to outlet.
Duty Cycle:
For proper operation of your air compressor, it is
recommended that a 50% duty cycle be maintained; that is,
the air compressor should not run more than 5 minutes in any
10 minute period.
