GENERAL INFORMATION
You have purchased an air compressor unit consisting
of a 2 cylinder, single-stage air compressor pump, an
air tank, wheels, handle, associated controls and in-
struments. You may also find an air chuck.
Your air compressor can be used for operating paint
spray guns, air tools, caulking guns, grease guns, air
brushes, sandblasters, inflating tires and plastic toys,
spraying weed killers, insecticides, etc. An air pressure
regulator is recommended for most of these applica-
tions.
Separate air transformers which combine the functions
of air regulation and/or moisture and dirt removal should
be used where applicable.
GLOSSARY
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.
ASME: American Society of Mechanical Engineers;
made, tested, inspected and registered to meet the
standards of the ASME.
CFM: Cubic feet per minute.
California Code: Unit may comply with California Code
462 (L) (2)/(M) (2). Specification/model label is on the
side of the tank on units that comply with California
Code.
Unloader Blow-Off Pressure: All models are continu-
ously running outfits controlled by tank pressure. When
the maximum tank pressure is obtained, the unloader
valve will blow-off. This will cause the compressor to
exhaust the air to the atmosphere and not the tank. This
decreases the load on the engine and allows it to run at
a near no-load condition.
Unloader Reset Pressure: When the tank pressure
drops to a pre-determined point, the unloader valve
closes. The tank pressure will now increase until it
reaches the unloader blow-off pressure.
All DeVilbiss Air Power manufactured air compressors should be operated on not more than a 50% duty cycle. This
means an air compressor that pumps more than 50% of one hour, is considered misuse, because the air compressor
is undersized for the required air demand. Maximum compressor pumping time per hour is 30 minutes.
