Air Dryer
Bendix

Moisture control and air drying module for heavy-duty braking systems uses a heated desiccant chamber to deliver dry, contaminant free air to the brake actuators. The integrated 24 V heating element delivers 90 W of heat to maintain desiccant efficiency in cold operating environments, reducing moisture carryover that can cause corrosion and freezing of valves and seals. Purge performance is managed by a soft seat purge valve which minimizes purge shocks and wear while maintaining reliable operation. The assembly includes the core desiccant and essential mounting provisions, featuring four mounting holes to ensure secure installation in standard brackets and shields. The porting scheme provides supply and delivery threads sized 1/2-14 NPT, control port 1/4-18 NPT, and an extended purge port 1/8-27 NPT that is plugged in typical configurations. VMRS code 013-010-252 places this module within the Bendix compressed air family and aligns with common repair and replacement workflows. In service, this unit reduces moisture related failures in downstream components, supports consistent brake response, and improves fleet uptime by limiting water vapor in the air system across climate ranges. Cross references are not listed; category context 41443 identifies it as part of the heavy truck air system category.
