Product Description
The Bendix 5008574 AD-IS Standard Purge Reservoir Assembly is a genuine replacement compressed air reservoir designed for compatible Bendix AD-IS air dryer systems. With a 200-cubic-inch capacity, this reservoir stores compressed air used during the air dryer's purge cycle, supporting effective desiccant regeneration and moisture removal.
During normal operation, the air dryer removes moisture and contaminants from compressed air before it enters the vehicle's braking system. When the compressor reaches its unloading cycle, the purge reservoir supplies stored air to help regenerate the desiccant material, allowing the air dryer to maintain efficient moisture removal during subsequent operating cycles.
Featuring a compact cylindrical construction, the Bendix 5008574 provides dependable purge air storage in heavy-duty commercial vehicle applications. Its four-hole SAE mounting arrangement is designed for compatible AD-IS air dryer installations.

The Bendix 5008574 provides the required purge air volume for supported standard-purge AD-IS configurations. Replacing a damaged, corroded, or leaking reservoir can help restore proper operation of the air treatment system.
This reservoir is different from the Bendix 5009028N extended purge reservoir, which has a larger 300-cubic-inch capacity and a longer body. The two reservoirs should not be substituted for one another without confirming the air dryer system requirements.
Before ordering, verify the original reservoir part number, mounting configuration, purge volume, and air dryer model. Air brake reservoirs must be installed and tested according to the manufacturer's service procedures.
Bendix's official quick-reference catalog identifies 5008574 as the 200-cubic-inch standard purge reservoir with a 9-inch diameter, 3.9-inch length, and four-hole SAE mounting.
