Air Dryer Assembly
Bendix

A moisture-control and pressure-regulating module designed for reliable drying of compressed air, this assembly plays a pivotal role in protecting braking components, airbags, and pneumatic tools from moisture-related degradation. Its cartridge thread size of M39X1.5-6H RH ensures compatibility with a broad range of Bendix dryer cartridges, while the 5/8 STC supply port and 1/4-18 NPT auxiliary delivery port accommodate standard plumbing configurations. A 12-volt heater maintains performance in extreme temperatures, preventing freeze-up in cold climates and improving cycle reliability. Performance settings include cut-in at 110 psi and cut-out at 130 psi, with safety valve activation at 153 psi and auxiliary delivery opening pressures at 55 and 85 psi. Temperature ratings span from -40°F to 160°F, enabling operation across diverse environments. Construction features a standard cartridge type with a 2-way sealed male connector, and governor integration ensures controlled air drying without excessive cycling. Included is the dryer assembly itself, offering a critical safeguard against corrosion, ice formation, and contaminants in the air system, which translates to longer service life for downstream components and more stable braking performance. Category context 41443 highlights its role in drying and conditioning compressed air within heavy-duty systems.
