Wedge Wire Screens for Filtration & Separation – Durable & Custom-Made
Wedge wire screen, also known as Johnson screen or profile screen, is a precision filtration component made by welding V-shaped wedge wires onto support rods. With a filtering accuracy ranging from 15 to 800 microns, it is commonly used to manufacture filter plates, filter baskets, and slot tubes. These screens are known for their high strength, hardness, wear and corrosion resistance, uniform slot openings, and excellent seepage performance. They are also easy to clean, resistant to clogging, and suitable for both backwashing and high-pressure cleaning environments.
In industries where precision filtration and durability are critical, wedge wire screens from Ambani Metals stand out as a trusted choice. As a reputed manufacturer and supplier, we specialize in high-performance screen elements designed for efficient separation and filtering across various sectors.
As a reputed wedge wire screen supplier, Ambani Metals provides screens known for their high strength, hardness, wear resistance, corrosion resistance, and uniform slot structure. These features ensure excellent seepage, easy cleaning, and resistance to clogging or backwashing, making them suitable for demanding filtration environments.
The wedge wire screen tube, also referred to as a round slot tube, is a popular option made from stainless steel due to its superior chemical stability and corrosion resistance. It comprises spirally wound surface profiles welded onto support profiles, ensuring high structural integrity and performance. Manufactured on automated machines, these tubes are available in both standard and precision variants, with the latter used in high-accuracy filtration systems where tighter tolerances are required.
Ambani Metals offers a variety of wedge wire screen types, including economical continuous-slot designs for general use and perfectly round types for high-precision applications. Whether used for dehydration, desliming, or solid-liquid separation, wedge wire screens from Ambani Metals provide excellent load-bearing capacity, rigidity, and versatility in design.
Each screen is custom-manufactured to fit specific equipment and filtration requirements, with a range of aperture sizes and profiles to reduce pegging and ensure efficient operation, even in the most difficult processing conditions.
