This stainless steel pressure bag filter housing is a pressure-type liquid solid separation equipment, widely used for industrial water pretreatment, circulating water, wastewater and raw water purification. Made of SS304 or SS316L stainless steel. Single-bag & multi-bag optional, quick open lid design for fast filter bag replacement. Internal stainless steel support basket prevents filter bag collapse. Accept custom size, pressure rating, inlet/outlet connection and surface finish. OEM available.
Product Overview
Our stainless steel bag filter housing is pressure-driven liquid filtration equipment. Liquid enters the housing and passes through filter bags inside, suspended solids, sediments and impurities are trapped by filter bags, clean liquid flows out. It is widely adopted in industrial water treatment and other liquid filtration processes.
Constructed from SS304 or SS316L stainless steel with precision TIG welding. Surface finish: sandblasting / mirror polishing. Available in single-bag and multi-bag versions (1~18 bags). Quick-opening bolt / clamp lid for tool-free bag replacement, reduces maintenance downtime. Built-in stainless steel perforated support basket to avoid bag bursting under pressure, eliminate bypass risk. Standard equipped with pressure gauge ports, vent port and drain port. Inlet & outlet: flange / threaded / tri-clamp connection options.
