DC4439-GSC-H3-NXFR255 Cartridge Filter – 15″ x 39″, Nanofiber Flame Retardant, 255 Pleats, Gasketed Snapband Closed End

The DC4439-GSC-H3-NXFR255 is a high-efficiency flame-retardant cartridge filter engineered for use in applications involving fine, combustible, or hazardous dust. Made with NXFR media, a nanofiber-treated cellulose/polyester blend with flame-retardant properties, this filter delivers exceptional surface-loading performance, long filter life, and spark suppression capabilities for dust collection systems in environments like welding, metalworking, thermal spray, and battery manufacturing.

It measures 15 inches OD by 39 inches in length and features 255 pleats, offering approximately 240–260 sq. ft. of filtration area. The GSC (Gasketed Snapband Closed) end cap style includes an open top with molded gasket and a snapband-sealed closed bottom, ideal for vertical mounting in round-housing collectors. The H3 heavy-duty support core ensures structural integrity during high-pressure pulse-cleaning cycles.
