Product Description
The Bendix 5009028N AD-IS Extended Purge Reservoir Assembly is a genuine replacement component designed for compatible Bendix AD-IS air dryer systems in heavy-duty commercial vehicles. Featuring a 300-cubic-inch capacity, this reservoir stores compressed air used during the air dryer's purge cycle to help remove accumulated moisture from the desiccant cartridge.
The extended purge design provides additional stored air volume for the regeneration process, helping the air dryer maintain effective moisture removal during demanding commercial vehicle operation. By supporting proper desiccant regeneration, the reservoir contributes to cleaner, drier compressed air throughout the vehicle's pneumatic braking system.
Featuring a durable cylindrical construction and four-hole SAE mounting arrangement, the Bendix 5009028N is designed for direct connection to compatible AD-IS air dryer assemblies without requiring separate connecting hoses.

The Bendix 5009028N is specifically designed for the extended purge configuration of the AD-IS air dryer. Its 300-cubic-inch capacity provides more purge air volume than the standard 200-cubic-inch reservoirs used in other AD-IS configurations.
Common catalog references include Bendix 5009028, 5009028BXW, 5011326, 801346, and 802632. These references should be verified for interchangeability before substitution.
Before ordering, verify the original reservoir part number, required purge volume, mounting arrangement, and air dryer configuration. Standard and extended purge reservoirs have different capacities and should not be interchanged without confirming compatibility.
The Bendix 5009028N is the purge reservoir assembly only. The complete air dryer, desiccant cartridge, and related pneumatic components are sold separately.
Bendix's official quick-reference guide confirms the 9-inch diameter, 6-inch length, 300-cubic-inch capacity, and four-hole SAE mounting arrangement.
