BENDIX® BA-922® SAE UNIVERSAL FLANGE AIR COMPRESSOR
High output compressed air generation for ultra
demanding commercial & industrial applications.
Experience Counts
For generations, Bendix Commercial Vehicle Systems (Bendix) has been
leading the way in air charging system experience and expertise. More
fleets specify our hard-working products and systems than any other.
And now Bendix continues its legacy of quality and innovation by
releasing the next generation of high-performance compressor options
– the Bendix
®
BA-922® SAE Universal Flange Mount series.
An Ideal Solution For A Wide Range Of
Unique Applications
Utilizing standard SAE B and SAE C flanges, the Bendix® BA-922® SAE
compressors are designed to address a wide variety of commercial and
industrial applications. The clock-able front adapter allows the
compressors to be easily mounted in several different positions
depending on your requirements.
Building On The Power Of The Bendix
®
BA-922® Compressor:
High Air Delivery
A dependable workhorse, the Bendix BA-922 compressor provides
maximum air delivery even at low speeds. Its high-output, two-cylinder
design supplies 32 cfm (cubic feet per minute) displacement at 1,250
rpm (revolutions per minute). Power like this delivers the ability to
recharge the system quickly and efficiently – even at low speeds –
making it ideal for more demanding brake system applications. That’s
important, since high output results in lower duty cycle, and lower duty
cycle means longer compressor life.
Ideal for niche industrial, agricultural and
petroleum applications, the universal flange
model . . .
Features an adapter mount to meet SAE J744
hydraulic pump, engine & motor mounting,
and drive dimensions standards;
Can be mounted at several different angles
depending on physical constraints and
application necessities; and
Is driven by an engine PTO, hydraulic motor,
or electric motor. Belt drive version available
with an overhung load adapter bearing.
High Thru-Drive
Unlike other high-air-output compressors, the Bendix
standard design is capable of powering a 25 horsepower accessory,
while the SAE Universal Flange model incorporates a built in 9-tooth SAE
A spline in the rear for an accessory pump or drive.
Effective Cooling Systems
The cylinder head of this hard working unit provides lower discharge air
temperatures by incorporating highly effective cooling surfaces, thus
reducing carbon formation and producing higher air quality. Minimizing
discharge temperature increases the service life of downstream air
components, such as the air dryer and valves.
Compact, Lightweight Design
Highly efficient, the Bendix BA-922 two-cylinder compressor replaces
earlier four-cylinder designs. While its volume output is similar to the
®
Bendix
weighs 33 percent less thanks to its optimized design and aluminum
components. What's more, its compact size enables it to meet even the
most demanding installation constraints in tight engine compartments
without compromising its high-air-output capability.
Tu-Flo® 1400 compressor, the unit is 4½ inches shorter and
