Wedge Wire Filter Element for Industrial Filtration Systems
Precision-engineered wedge wire filter elements designed for high flow rate, long service life and reliable particle retention in demanding industrial filtration applications.
What Is a Wedge Wire Filter Element?
A wedge wire filter element is a rigid, self-supporting filtration component manufactured by resistance welding V-shaped profile wires onto support rods. Compared with perforated or mesh filters, wedge wire elements provide precise slot openings, high mechanical strength, and excellent backwash performance. They are widely used as: wedge wire filter cartridge wedge wire candle filter wedge wire filter strainer in pressure filters, automatic backwashing filters, and process filtration systems.
