PB57581-UBL-H6-SB35 Pleated Bag Filter – 5.75″ x 81″, Spunbond Polyester, 35 Pleats, Urethane Bottom Latch (UBL), Extended Heavy-Duty Core

The PB57581-UBL-H6-SB35 pleated bag filter is designed for use in large dust collection systems that require ultra-long filters for maximum coverage and airflow. Constructed from spunbond polyester (SB) media, this filter offers excellent abrasion resistance, moisture durability, and reusability for dry particulate environments such as cement, grain, plastic, fertilizer, and bulk material handling.

This model features a 5.75″ outer diameter and 81″ length with 35 pleats—providing substantial surface area for extended filtration cycles and lower system pressure drop. The UBL mounting style ensures quick, tool-free installation in bottom-latch style pulse-jet collectors. The H6 galvanized steel core delivers reliable support across the full filter length.
