The Bendix

Air Power Series – a tradition continues…

BA-921

™

Compressor

Lighter weight and more compact to address OE fit constraints, this dynamic

single cylinder compressor utilizes reed valve technology for improved

operating efficiency. The BA-921

™

compressor is available for a wide range

of build platforms, including specialty vocational applications, and features:

• The highest boost capability on the market today – 43.5 psig

• High thru-drive capacity – up to 125 foot pounds

• Improved air quality along with faster recovery

• A drive train saver crankshaft to prevent damage to the gear train or

auxiliary components

BA-922

™

Compressor

When you need maximum air delivery, the BA-922

™

“Big Twin” air compressor is

for you. This high air output compressor is smaller than previous 4 cylinder

models, but still supplies 32 cfm (at 1250 RPM) to meet the needs of even the

most demanding specialty vocational applications. The BA-922

™

compressor

employs many of the same exceptional design elements as the BA-921

™

compressor,

its single cylinder partner, including the robust reed valve technology. The

powerful BA-922

™

compressor also incorporates:

• Standard North American unloader valving – eliminating the special valve

requirements normally associated with 2 cylinder high output compressors

• A drive train saver crankshaft to prevent damage to the gear train or auxiliary

components

• High thru-drive capacity – up to 125 foot pounds
