Air Filter Element - Puraguard, Oil Coalescing RX Cartridge
Bendix

This filtration cartridge is designed for Puraguard oil coalescing RX systems and features a spin-on configuration with identical exterior geometry to ensure seamless integration into existing housings. It shares the same dimensional footprint—7.40 inches high with an 8.40 inch outer diameter and a 1 1/4-7 UNC-2B thread—allowing rapid service in field and depot settings. The coalescing construction targets multi-phase filtration by removing oil aerosols before the air reaches downstream components, substantially improving air purity and protecting control valves, actuators, and braking electronics from oil carryover. With a maximum operating pressure of 150 psi and a working temperature range from -40 to +160 Deg.F, the cartridge remains effective across standard heavy-duty vehicle duty cycles. VMRS 013-010-129 anchors it in the same air system filtration family as related parts, enabling unified maintenance planning. Cross references ABP N13 35110240160 support cross-compatibility during part substitutions. Practically, the element reduces maintenance downtime by extending service life of downstream air treatment stages, delivering steadier performance in mixed duty cycles, and contributing to more reliable air-brake operation under varying ambient conditions. Ensure proper seating and thread alignment to prevent leaks and maintain effective coalescence of oil-laden air.
