The PB62557-MTL-H4-SB45 is an extra-long, washable cartridge filter designed for industrial dust collection systems that require maximum surface area in a compact diameter form. Featuring SB media (Spunbond Polyester), this filter is highly resistant to moisture, abrasion, and fibrous dust, making it ideal for demanding environments such as grain processing, fertilizer production, food and feed manufacturing, and other agricultural or chemical facilities.

It measures 6.25 inches OD by 57 inches in length, with 45 pleats, delivering approximately 65–70 sq. ft. of total filtration area. The Metal Top Latch (MTL) provides a secure, tool-free installation into compatible twist-lock or latch-seating systems.
