Description
The AD Series Powerex Duplex Air Compressors have been
designed, broken-in and tested to meet the most demanding
specifications for low oil carryover and long life in the
pneumatic climate control industry.
The units consist of two equally rated motor-compressor
assemblies mounted on a single ASME tank. The compressor
motors are NEMA Class B design. The AD Series Compressors
are ideal for instrumentation systems requiring an alternate
compressor for standby or overload capacity. See Table 1 for
motor sizes and air delivery capacities available.
Compressor assemblies are available with or without a factory
mounted basic or deluxe alternator/motor starter package. An
unloading feature is included on all compressors to provide
loadless starting. Models with an alternator are prewired and
ready for operation. Internal wiring allows for shutdown of
either compressor for repair while the other compressor is
running.
An alternating type operation is desirable for many reasons.
When a duplex air compressor is alternated, the temperature
of both units is kept above the ambient dew point to minimize
moisture deterioration and corrosion. Also, the reduction in
on-time provides a lower average head temperature with
reduced oil entrainment potential and improves the motor life
by holding down the average heat rise.
All units are run through a factory break-in and are tested
for air delivery, leakage and power consumption. Tank-
mounted units are shipped with a proper fill of compressor
oil in the crankcase and are furnished with an intake filter
with a replaceable cartridge. This filter is designed to remove
contaminates in the inlet air, as well as provide a quiet
operation.
All models have conveniently located oil drain and filler ports
to facilitate routine maintenance. Tanks have a condensate
drain valve with an extension for easy access. Mounting bases
are slotted to allow tension adjustments to aid in maintaining
proper compressor and motor alignment while adjusting
tension.

Climate Control Duplex
Basic Alternator Package
All Powerex duplex air compressors may be ordered with a
simplified line voltage basic alternator package. The basic
alternator package consists of an alternating coil and two
magnetic motor starters. Motor starters are selected and
wired for intended input voltage and are furnished with
properly sized overload heaters.
Automatic Tank Drain
Powerex air compressors may be ordered with a manual
or electric type automatic tank drain. A manual drain
attachment is furnished with each unit.
Vibration Dampening Pads
Waffle type design vibration pads are provided as standard
equipment.
Operation
Factory calibrated DPST pressure switches provide lead and lag
settings. When using an alternator-starter package, the lead
switch energizes the alternator and the alternator activates
the compressor that was on standby during the previous cycle.
If the demand exceeds the capacity of one compressor, the lag
switch will cause both compressors to run simultaneously. Upon
failure of either compressor, the lag switch will continue to
activate the workable compressor.
Single-phase motors (3/4 HP & 1 HP) have built-in overload
protection with manual reset. Three-phase motors require
a magnetic starter and three overload heaters. Heaters are
included with three-phase compressors that have a factory
mounted alternator.
NOTE: All pump models operate turning clockwise opposite
the motor shaft / pump flywheel / belt guard side of the unit.
Improper rotation will cause oil to spray out of the breather
vent opening.

HEREIN, UNDER NO CIRCUMSTANCES SHALL POWEREX BE LIABLE FOR ANY INCIDENTAL, CONSEQUENTAL, PUNITIVE, SPECULATIVE OR
INDIRECT LOSSES OR DAMAGES WHATSOEVER ARISING OUT OF OR IN ANY WAY RELATED TO ANY OF THE PRODUCTS OR GOODS SOLD

Warranty Disclaimer. Powerex has made a diligent effort to illustrate and describe the Products in this literature accurately; however,
such illustrations and descriptions are for the sole purpose of identification, and do not express or imply a warranty that the Products are
merchantable, or fit for a particular purpose, or that the Products will necessarily conform to the illustrations or descriptions.
Product Suitability. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of Products for
certain purposes, which may vary from those in neighboring areas. While Powerex attempts to assure that its Products comply with such
codes, it cannot guarantee compliance, and cannot be responsible for how the product is installed or used. Before purchase and use of a
Product, please review the Product applications, and national and local codes and regulations, and be sure that the Product, installation,
and use will comply with them.
Claims. Claims pertaining to the Products, with the exception of warranty claims, must be filed with Powerex within 6 months of the
invoice date, or they will not be honored. Prices, discounts, and terms are subject to change without notice or as stipulated in specific
Product quotations. All agreements are contingent upon strikes, accidents, or other causes beyond our control. All shipments are
carefully inspected and counted before leaving the factory. Please inspect carefully any receipt of Products noting any discrepancy or
damage on the carrier’s freight bill at the time of delivery. Discrepancies or damage which obviously occurred in transit are the carrier’s
responsibility and related claims should be made promptly directly to the carrier. Returned Products will not be accepted without prior
written authorization by Powerex and deductions from invoices for shortage or damage claims will not be allowed. UNLESS OTHERWISE
AGREED TO IN WRITING, THESE TERMS AND CONDITIONS WILL CONTROL IN ANY TRANSACTION WITH POWEREX any different
or conflicting terms as may appear on any order form now or later submitted by the buyer. All orders are subject to acceptance by
Powerex.
