The AJR ESP Extended Surface Pleat (ESP) Bag Filter is designed for high dirt holding capacity and extended service life—up to 4X longer than a standard nominal bag. Built with unique internal pleats and two layers of pleated felt, ESP bags reduce changeout frequency, increase product throughput, and minimize downtime. Available in polyester or polypropylene felt with micron ratings from 1 to 100, ESP bag filters meet FDA requirements for food contact and are offered with galvanized steel, stainless steel, or plastic flange options. Total Filtration Services (TFS) supplies AJR ESP filters to support reliable and efficient liquid filtration across multiple industries.
