DC1236-WC-H3-CX220 Cartridge Filter – 12.75″ x 36″, 80/20 Cellulose/Polyester, 220 Pleats, Wire Closed End

The DC1236-WC-H3-CX220 is a high-efficiency, dry-use cartridge filter designed for general industrial dust collection applications involving dry, non-hygroscopic particulate. It features CX media, an 80/20 cellulose/polyester blend that provides a balance of durability, dust-loading capacity, and cost-effectiveness — making it ideal for metalworking, woodworking, plastics processing, and general manufacturing.

With dimensions of 12.75 inches OD by 36 inches in length, this model includes 220 pleats, offering approximately 180–200 sq. ft. of filtration surface area. The WC (Wire Closed) end cap style includes an open top with gasket and a closed bottom reinforced with wire mesh, providing extra rigidity and secure fitment in vertical mounting systems. The H3 heavy-duty support core ensures strength during pulse-cleaning and under moderate dust loading conditions.
