The Alltrux ATX27091 Oil Coalescing Cartridge replaces AC1001C and is designed to remove oil aerosols and fine contaminants from the compressed air supply in heavy-duty truck air dryer systems. This coalescing filter cartridge plays a critical role in maintaining clean, conditioned air for reliable air brake system performance and long-term component protection.

Installed within the air dryer assembly, the coalescing cartridge captures oil mist and microscopic particles that can otherwise contaminate valves, chambers, and other pneumatic components. Maintaining proper filtration helps reduce internal air system wear, prevents sticking valves, and supports consistent brake response in demanding fleet and vocational operating conditions.

Regular replacement of the oil coalescing cartridge is recommended as part of preventive air system maintenance to ensure optimal air dryer efficiency and protection of downstream air brake components. Always verify air dryer model compatibility and service interval requirements prior to installation.
