Glossary
Become familiar with these terms before operating the unit.
AIR DELIVERY - A combination of psi and SCFM. The air delivery required by
a tool is stated as (number) SCFM at (number) psi. The combination of these
figures determines what size unit is needed.
AIR TANK CAPACITY - The volume of air stored in the tank and available for
immediate use. A large tank allows the intermittent use of an air tool with an air
requirement higher than the compressor’s rated delivery.
ASME SAFETY VALVE * - This valve automatically releases air if the tank pressure
exceeds the preset maximum.
CLICK-TO-SET REGULATOR - The regulator controls the amount of air pressure
released at the hose outlet to the proper amount needed to operate an air tool or
spray gun.
CUT-IN/CUT-OFF PRESSURE - Specific psi at which a compressor starts and
stops while refilling the air tank.
EASY DRAIN KNOB - This knob is used to drain moisture from the tank daily to
reduce the risk of corrosion.
FOOT PEDAL ON/OFF SWITCH - Used to turn the compressor on and off. Press
firmly.
MOTOR PROTECTION - If the unit is over worked, a thermal switch will shut
unit off. If this happens, turn unit OFF the ON/OFF Switch, wait 30 minutes to
cool, turn ON the ON/OFF Switch again to resume work.
OUTLET (TOOL) PRESSURE GAUGE - Displays the current outlet pressure to the
tool in psi. It is regulated by the regulator knob.
PRESSURE SWITCH -Shuts the compressor off automatically when tank
pressure reaches the maximum preset pressure. The compressor will
automatically restart when it reaches the minimum preset pressure.
PSI (POUNDS PER SQUARE INCH) - Measurement of the pressure exerted by
the force of the air. The actual psi output is measured by a pressure gauge on the
compressor.
SCFM (STANDARD CUBIC FEET PER MINUTE) - Sometimes called CFM (Cubic
Feet per Minute). Measurement of air volume delivered by the compressor.
TANK PRESSURE GAUGE - Indicates tank pressure in psi.
TOOL STORAGE - The open space on top of compressor is designed for tool
storage. Specific Campbell Hausfeld tool kits will fit in this storage area.
* ASME: American Society of Mechanical Engineers. ASME tanks are
manufactured to ASME requirements.
