The DC1326-OO-HM-NXFR350 is a premium industrial cartridge filter built for demanding dust collection applications involving fine, combustible, or hazardous dust. This filter uses NXFR media—a nanofiber-coated, flame-retardant 80/20 cellulose/polyester blend—providing MERV 15+ filtration efficiency, superior surface loading, and added fire safety.
With a 13.20-inch outer diameter, 26-inch length, and 350 pleats, this filter delivers approximately 270–285 sq. ft. of high-efficiency filter area. The Open/Open (OO) end cap configuration includes gaskets on both ends, allowing for easy installation in standard dual open-end systems.
NXFR filters are ideal for industries requiring NFPA compliance or protection from spark or ignition sources—such as metal processing, welding, powder coating, battery manufacturing, and high-dust-load operations.
