Air Dryer Assembly AD-9 RX Puraguard 12V HS
Bendix

This high-utility dryer assembly variant integrates Puraguard RX technology with a 12-volt electrical supply, delivering rapid desiccant regeneration and resilient moisture control for demanding duty cycles. The 12 V HS specification supports compact electrical integration in modern trucks where auxiliary power budgets are tight, enabling fast purge cycles and steady air quality improvements. VMRS 013-010-252 places it in the dryer family, while the RX designation indicates enhanced moisture-removal performance. Cross references may be absent, but the unit aligns with Puraguard RX offerings that emphasize robust condensate separation and reduced downtime due to moisture-related faults. In field use, the assembly contributes to more reliable braking system performance, less moisture-induced corrosion in valves, and more predictable air actuator operation under variable ambient temperatures. When selecting this variant, confirm electrical availability and compatibility with the existing Puraguard RX platform and the vehicle’s control system.
