GLOSSARY

DUTY CYCLE

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

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.

the air compressor is undersized for

the required air demand. Maximum

compressor pumping time per hour is

30 minutes.

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.
