Your air compressor can be used for operating paint
spray guns, air tools, blow guns, nailers/staplers, air
brushes, and inflator kits. An air pressure regulator is
required for most of the applications.
An in-line air filter which removes moisture and dirt
from compressed air should be used where applicable.
An in-line regulator can be used if a more precise
adjustment of air pressure is needed downstream.
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.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
Cut-In Pressure: While the motor is off, air tank
pressure drops as you continue to use your acces-
sory. When the tank pressure drops to a certain low
level and the pressure switch lever is in "Auto", 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 com-
pressor 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.”
CSA: Electrical products sold in Canada are required
to be certified to the applicable CSA standard (s).
Canadian Standards Association (CSA) is a standards
writing and safety testing organization. Products that
are CSA certified have been evaluated and tested and
found to meet or exceed the applicable CSA standard
(s) for safety and electrical performance.
