GETTING TO KNOW YOUR COMPRESSOR

Regulator
Outlet Pressure Gauge
Air Filter
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.
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.
Amps or Amperage - A measure of the electrical force minus the resistance on an electrical line. This air
compressor requires 15 amps for operation. Be sure the compressor will operate on an electrical line with
the proper amps. If other appliances operate on the same line, they will reduce the available amps. If the
amperage is not adequate, the result will be blown fuses or tripped circuits.
Volts or Voltage - A measurement of the force of an electrical current.
Cut-in / Cut-off Pressure - Specific psi at which a compressor starts and stops while refilling the air tank.
Pressure Switch - Auto On/Off Switch - In the
"Auto On" position, the compressor shuts off
automatically when tank pressure reaches the
maximum preset pressure. After air is used from the
tank and drops to a preset low level, the pressure
switch automatically turns the motor back on. In
the "Off" position, the compressor will not operate.
This switch should be in the "Off" position when
connecting or disconnecting the power cord from
the electrical outlet. (Figure 2)
When the pressure switch turns the motor off you
will hear air leaking out of the pressure switch
unloader valve for a short time. This releases the
air pressure from the discharge tube and allows the
compressor to restart easier.
