The primary advantages of bag filters are their high dirt holding capacity,large filtration area,and quick,easy bag replacement.Single-bag housings allow for bag change without stopping the process,minimizing maintenance costs.Bags are made from various materials like Polypropylene(PP),Polyester(PET),and Nylon,meeting different chemical compatibility needs.They combine surface and depth filtration for high efficiency.Housings often feature a quick-open clamp for easy access.Their compact design saves space,and both capital and operating costs are relatively low.

Flow rates for single-bag housings typically range from 1 to 100 m³/h.Housing materials include carbon steel,304 SS,and 316 SS,with internal surfaces coated or polished.Bag pore sizes range from 1 to 800 microns.Standard bag lengths include 180mm,420mm,and 810mm.Maximum operating pressure can reach 1.0 MPa,and temperature limits depend on gasket material(e.g.,EPDM,NBR,PTFE).Connections include flanged and tri-clamp types.
Extensively used for fine filtration in paints,inks,and plating solutions;clarifying filtration in food&beverage for syrups,edible oils,and beer;filtering chemical reagents and pharmaceutical fluids;recycling metalworking coolants;and serving as a safeguard filter for RO systems,capturing trace suspended solids that may be released from upstream piping.It is an indispensable final barrier for protecting sensitive equipment.
