BENDIX® BA-922® AIR COMPRESSOR

High air output compressor for demanding transit vehicle applications.

Experience Counts

For generations the Bendix® name has meant quality, reliability and durability when it comes to your vehicle’s air charging system. With transit vehicles becoming more sophisticated, and compressed air requirements increasing, Bendix offers this next generation high-performing, energy-saving compressor option.

High Air Delivery

The Bendix® BA-922® air compressor is unique because it provides high air delivery even at low speeds, a critical feature for urban transit routes. This compressor’s ability to recharge the system quickly and efﬁ ciently at those low speeds makes it ideal for more demanding brake system applications, such as transit coaches that are often starting, stopping, lifting, etc. It is a highoutput, two-cylinder compressor that supplies 32 cfm (cubic feet per minute) displacement at 1,250 rpm (revolutions per minute). That’s important, since high output results in lower duty cycle, and lower duty cycle results in longer compressor life.

High Thru-Drive

Unlike other high-air-output compressors, the Bendix®

BA-922 powering a 25 horsepower accessory at any speed. If your application requires higher thru-drive power – an option that may be possible – it will be necessary for you to consult with one of the experienced Bendix air compressor engineers.

Efficient Unloader Valving

By incorporating integral unloader valving in the cylinder head, the powerful Bendix valve requirements. This unique design not only reduces the number of ports, it also reduces unloaded horsepower draw.

BA-922® air compressor eliminates special

Effective Cooling Systems

The cylinder head of this hard working unit provides lower discharge air temperatures by incorporating highly effective cooling surfaces, thereby reducing carbon formation and resulting in higher air quality. Minimizing discharge temperature increases the service life of downstream air brake components, such as the air dryer and valves.

Compact, Lightweight Design

Highly efﬁ cient, the Bendix® BA-922® two-cylinder air compressor replaces earlier four-cylinder designs. While its volume output is similar to the Bendix and lighter compressor is 4½ inches shorter and weighs 33 percent less due to its simpler design and extensive use of aluminum components. And its compact size enables it to meet OE installation constraints in tight engine compartments without compromising its high-air-output capability.

Requirements

As the source of energy for a vehicle’s air brake system and accessories, the Bendix vehicle’s engine and utilizes the vehicle’s lubrication and cooling system. Because of these shared systems, regular vehicle maintenance, such as oil changes and coolant ﬂ ushing, is critical. This vehicle maintenance – along with regular air brake system and air accessory maintenance – keeps the compressor running efﬁ ciently.
