Wedge Wire Screen

Providing Effective Solid Liquid Filtration

Wedge Wire Screen compact construction & high filtration accuracy

Wedge wire screens are composed of wedge wires and support profiles, which have a “V” shaped surface and a “groove” shaped interior, so they are also known as “V” shaped wire screen or groove wire screen. Wedge wire has a triangular cross-section, a large filtration area, and a high porosity, which can effectively prevent clogging and damage. Wedge wire screens feature high strength, high precision, excellent corrosion resistance performance, high temperature resistance performance, not easy to clog, etc. Therefore, it is widely used in the filtration and separation fields of water treatment, petrochemical, food processing, and other industries.

Working Principle

Wedge Wire Screen is a high-performance metal screening element widely used in industrial screening, filtration, dehydration and desliming. Boasting excellent strength, rigidity and load-bearing capacity, it can be fabricated into various rigid filter structures.

Made of V-shaped surface wires and support profiles, it features precisely controlled slot openings for efficient filtration. Flow direction can be designed as either outside-to-inside or inside-to-outside, adapting to diverse industrial process requirements.

Wedge Wire Screen Advantages

Its uniform filter slots and high precision ensure the effective retention of the filter medium.
Wedge wire screen has a larger circulation area compared with other screens.
The tiny gaps between wedge wires form a smooth wedge-shaped cross section, which ensures no dead ends, excellent resistance to block, and easy backwashing (blow wash).
It has high mechanical strength and can withstand high pressure drops.
It is made of superior stainless steel wires (SUS304 and 316L) with strong corrosion resistance and high temperature resistance performances, and can totally adapt to various harsh environments.
It adapts to different forms of fluid direction with high strength, large flow, and high-pressure resistance performance.
It maintains stable filtration accuracy, can be reused repeatedly, and works reliably.
