Description
The AS Series Powerex Simplex Air Compressors have been
designed, broken-in and tested to meet the most demanding
specifi cations in the pneumatic climate control industry for
low oil carryover and long life.
All Powerex air compressors have reliable operation and
feature high quality construction and components. An
unloading feature is included on all compressors to provide
loadless starting. Oil entrainment is minimized by the use of
lap joint piston rings, low compressor speeds and a special
lubricating oil with a high fl ash point and low carbon
content.
Powerex compressor motors are NEMA Class B design. Singlephase motors have built-in overload protection and a DPST
disconnect switch. Three-phase motors require a manual or
magnetic starter and three overload heater coils which may
be ordered as a factory mounted and wired option.

Installation
MOUNTED AND CONNECTED OPTIONS
Magnetic Motor Starter
An optional magnetic motor starter which has been selected
and wired for the intended input voltage is available for all
units. All starters are furnished with properly sized overload
heaters.
Refrigerated Air Dryer
A factory mounted model Hankinson HPR 5-10 Series
refrigerated air dryer with automatic condensate drain trap
assembly, bypass valve is available as an option on all 3/4
through 3 Hp Powerex Simplex air compressors. Piping for air
dryer is done at the factory. Wiring to power source must be
done in the fi eld using integral cord and plug which fi ts into
a standard 120 volt receptacle.
Automatic Tank Drain
Powerex air compressors are ordered with either a manual or
electric type automatic tank drain. This unit is furnished with
a manual drain attachment.
Vibration Dampening Pads
Waffl e type design vibration pads are provided as standard
equipment.
Compressor RPM
Operation
Factory calibrated snap-acting DPST pressure electric
switches provide automatic cut-in and cut-out. Overpressure
protection is provided by an ASME safety relief valve. Receiver
tanks have a condensate drain valve with an extension for
easy access. All mounting bases are slotted for V-belt tension
adjustment to aid in maintaining proper compressor and
motor alignment.
All units are run through the factory break-in and are tested
for air delivery, leakage and power consumption.
Units are shipped with a proper fi ll of compressor oil in the
crankcase and are furnished with an intake fi lter/silencer with
a replaceable cartridge. This fi lter/silencer combination is
designed to remove contaminates in the inlet air and provide
quieter operation.
LUBRICATION
Check lubricating oil level at gauge. Refi ll if necessary. See
Figure 1.
Change oil according to maintenance schedule. Before
draining oil, remove oil supply cap and loosen oil drain cap to
release trapped air. Use Mobil Rarus 427
oils.
NOTE: All pump models operate turning clockwise opposite
the motor shaft / pump fl ywheel / belt guard side of the unit.
Improper rotation will cause oil to spray out of the breather
vent opening.
Dispose of oil in accordance
Compressor Capacity ACFM
with state or local codes.
