Air Dryer
Bendix

The air dryer assembly plays a pivotal role in protecting the braking system by removing moisture and contaminants from compressed air before it reaches valves and actuators. The detailed construction features a reservoir with a 10.20 inch diameter, a cartridge thread size of M41 X 1.50 mm, and a supply port thread size of 1/2-14 in, enabling robust plumbing and reliable sealing in rugged installations. Performance specifications include a heater rated at 90 W operating on 12 V, with pressure settings that govern start (105 psi) and stop (125 psi) thresholds, plus auxiliary delivery openings at 112 psi and 103 psi to support multi-point delivery. The minimum operating temperature is -40 Deg.F, ensuring cold-weather reliability, while the coalescing cartridge and governor are integrated to optimize moisture removal and system stability. A purge valve type DLU (Hard Seat) and full conductor access for service contribute to long service life and easy maintenance. This unit is cataloged under VMRS 013-010-252 with no cross references, and category context 41443 places it within the standard air dryer family used across commercial trucking to safeguard valve life and braking performance in varying climates and workloads.
