Welcome to Anping County Boli Hardware Wiremesh Products Factory – a reliable manufacturer with over 20 years of experience since 1998. Our 304 Stainless Steel Johnson Wedge Filter with V-shaped wire and 0.25mm slot is designed for high-precision filtration in demanding environments. The 1" BSP threaded connection ensures easy installation, while the robust stainless steel construction delivers exceptional durability and corrosion resistance. This filter is ideal for industries such as water treatment, petrochemical, food processing, and mining, where consistent performance and long service life are critical.
The unique V-shaped wire profile creates a continuous slot that minimizes clogging and allows for efficient backwashing. With a slot opening of only 0.25mm, it effectively removes fine particles while maintaining high flow rates. Each filter is manufactured with precision welding to ensure uniform slot width and structural integrity. Available in various lengths and diameters, our Johnson wedge filters can be customized to meet your specific application requirements.
