DC1326-OO-HM-CXFR350 Cartridge Filter – 13.20″ x 26″, Flame-Retardant 80/20 Media, Open/Open, 350 Pleats

The DC1326-OO-HM-CXFR350 is a flame-retardant cartridge filter engineered for industrial dust collection systems operating in spark-prone or combustible dust environments. Constructed with CXFR media—a flame-retardant treated 80/20 cellulose/polyester blend—this filter balances filtration efficiency, airflow, and added fire safety.

Measuring 13.20 inches OD and 26 inches in length, the filter includes 350 pleats, delivering approximately 270–285 sq. ft. of surface area for extended filter life and optimal pulse-cleaning performance. The OO (Open/Open) end cap configuration features gaskets on both ends and fits most dual open-end collector systems.

The CXFR media offers MERV 10–11 performance while meeting fire safety standards required for certain NFPA-compliant dust collection applications.
