The Conical Wedge Wire Filter Element 90×1020 is a high-strength, high-permeability filtration component manufactured from 304 or 316L stainless steel wedge wire. This conical wedge wire screen is engineered for solid-liquid separation, water treatment, oil and gas filtration, mineral processing, and industrial screening applications.
The element is constructed by automatically welding V-shaped profile wire onto longitudinal support rods. The V-shaped wire creates a continuous, uniform slot opening that widens internally, allowing liquid to flow through freely while preventing particles from wedging and blocking the screen. The conical design improves flow distribution, reduces pressure drop, and allows filter cake to release more easily during backwashing or vibration cleaning.

The Wedge Wire Filter Element serves critical filtration roles across numerous industries:
Water & Wastewater Treatment: Intake screening, backwash filter systems, industrial water treatment, municipal wastewater processing, drinking water purification, and cooling water systems. Wedge wire elements are the most popular mining and water treatment screen due to their strength and open area.
Oil & Gas Industry: Crude oil filtration, sand separation from produced fluids, natural gas processing, and petrochemical refining. The high mechanical strength and corrosion resistance make wedge wire filters ideal for harsh oilfield environments.
Chemical Processing: Filtration of acids, alkalis, organic solvents, and corrosive chemical streams. Catalyst recovery systems and chemical manufacturing processes benefit from the anti-clogging V-shaped design.
Mining & Minerals: Coal slurry dewatering, mineral processing, sand separation, and aggregate classification. The robust welded construction withstands abrasive conditions and heavy solids loading.

Q1: What materials are available for wedge wire filter elements?
A: Standard material is 304 stainless steel (as described here). 316L stainless steel is available for applications requiring enhanced corrosion resistance in chloride-rich environments (e.g., seawater, coastal installations). Other materials available upon request include Duplex stainless steel, 904L, Hastelloy C276, Monel, and Titanium.
Q2: What flow directions are available?
A: Both outside-in and inside-out flow configurations are available. The standard configuration for cylindrical wedge wire elements has the smooth surface of the profile wire on the inside, with filtration direction from inside to outside. Alternative flow directions can be designed to meet your specific application requirements.
Q3: What are the advantages of wedge wire over woven mesh?
A: Wedge wire outperforms woven mesh in several key areas:
Q4: How do I choose the right slot size?
A: Slot size depends on the particle size you need to retain and the required flow rate. Smaller slots provide finer filtration but lower flow. Huahang Filter can recommend the optimal slot size based on your application.
