CMHF Series High-Flow Coalescer Cartridges

Facet’s CMHF Series High-Flow Aviation Fuel Coalescers are high-flow aviation fuel coalescer cartridges designed for mission-critical Category M fuel filtration. These coalescer elements are built to remove ultra-fine solids and coalesce water in demanding aviation fueling systems where throughput, reliability, and downstream equipment protection are critical.

The CMHF Series uses multi-layered media and optimized cartridge geometry to support high flow rates while minimizing pressure drop. Compared with Type S-M options, CMHF coalescers offer up to 3x greater dirt-holding capacity, helping extend service intervals and reduce maintenance frequency. A permanently affixed gasket helps maintain a positive seal during installation and changeout.

Available in self-centering rod-mount and screw-base configurations, the CMHF Series can be matched to a range of Facet coalescer-separator housings. When used with companion SMHF separator cartridges in Facet coalescer-separator housings, these elements are specified for EI 1581, 7th Edition, Category M, Type S-LW horizontal applications. CLEAR Solutions can help match the correct element length and mount style for your system.
