The PB81239-CTL-H3-SB75 is a durable, washable cartridge filter designed for industrial dust collectors that use threaded center-mounting systems. Built with SB media (Spunbond Polyester), this filter excels in abrasive, sticky, or moist dust environments, offering long service life, moisture resistance, and repeatable washability.
It measures 8.12 inches OD by 39 inches in length, with 75 pleats, delivering approximately 90–100 sq. ft. of filtration surface area. The CTL (Center Threaded Lock) end cap design features a closed bottom with a centrally threaded mount for secure, vertical installation. The H3 heavy-duty core provides robust internal support for use in high-static or high-dust-loading applications.
This filter is ideal for use in grain handling, food production, fertilizer plants, plastics processing, and other environments requiring compact-diameter filters that stand up to harsh conditions.
