As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in producing high-quality Stainless Steel Wedge Filter Johnson Vee Wire Screen with a precise 0.25mm slot opening. Our decades of experience in wire mesh fabrication ensure that each screen delivers exceptional filtration efficiency, durability, and corrosion resistance. With an annual export value of US$5-10 million and serving clients across North America, South America, Europe, Asia, Africa, and Oceania, we are your trusted partner for industrial filtration solutions.
The Johnson Vee Wire Screen design features a continuous V-shaped profile wire wound around support rods, creating a robust and self-cleaning filter element. The 0.25mm slot width provides precise particle retention while maintaining high flow rates. Made from 304 grade stainless steel, this wedge filter offers excellent resistance to harsh chemicals, high temperatures, and mechanical stress, making it ideal for demanding applications such as water treatment, oil & gas, food processing, and mining.
