Specifications

When you need a reliable, high-performance air dryer for heavy-duty truck service, the Bendix 5004050 AD-IS Air Dryer from Wofford Truck Parts stands out. As an integrated solution, it combines the air dryer, purge reservoir, governor, and pressure-protection valves in one durable module. It features a ½″-14 NPT inlet for compressor discharge air, ¼″-18 NPT delivery ports to primary and secondary reservoirs, and multiple auxiliary delivery ports. A built-in 12 V/90 W heater prevents freezing, and a hard-seat purge valve ensures condensed moisture and contaminants are expelled during each purge cycle. With a nominal weight of around 15 lbs according to Haldex specs, the 5004050 is designed for efficient service and easier installation.

Selecting this module helps maintain air-brake system integrity, reduces water-related corrosion, and avoids the manual draining of reservoirs typical to older dryers. Wofford Truck Parts carries this genuine Bendix unit for quality service and fast replacement.
