Wedge Wire Panels

Wedge Wire Panels

Wedge wire panel is a type of filtration component commonly used in industrial applications. It consists of a surface of profiled wedge-shaped wires that are welded or looped onto support rods. The wires and support rods are usually made of stainless steel or other corrosion-resistant materials. The profiled wedge wires are V-shaped, with narrow gaps between them. This unique design allows for effective filtration and separation of solids from liquids or gases. The wedge wire panel acts as a sieve, with the liquid or gas passing through the gaps while retaining the solid particles.

Wedge wire panels offer several advantages, including high strength and durability, excellent filtration efficiency, resistance to clogging, and easy maintenance. They are available in different sizes, configurations, and slot openings to accommodate various filtration needs. Wedge wire panels are highly versatile and can be custom-designed to suit specific filtration requirements. They are used in various industries, including water treatment, oil and gas, pulp and paper, food and beverage, mining, and chemical processing. Common applications include dewatering, solids separation, media retention, and wastewater treatment.

Slot Openings: The size of the gaps between the wedge wires can be customized to accommodate the desired filtration requirements. This allows for precise control over the particle size retention or flow rate.

Profile and Wire Shape: The shape and profile of the wedge wires can be customized to suit specific filtration needs. Different wire shapes, such as triangular, trapezoidal, or round, can be used to achieve desired filtration efficiency and strength.

Panel Dimensions: Custom wedge wire panels can be manufactured in various dimensions to fit specific equipment or filtration systems. This ensures a seamless integration and optimal performance.

Material Selection: The choice of material for the wedge wires and support rods can be customized based on the application requirements. Common materials include stainless steel, duplex stainless steel, and other corrosion-resistant alloys.

What is the recommended wire diameter and support rod size for the wedge wire panel panels?

Structure of wedge wire panel

Wire Diameter: Wire diameters for wedge wire panels typically range from 0.5 mm to 5 mm. For general applications, a commonly used wire diameter range is between 1 mm and 3 mm. Thicker wire diameters, such as 4 mm or 5 mm, are often employed for heavy-duty applications or situations that require higher strength and durability.

Support Rod Size: Support rod sizes for wedge wire panels usually range from 2 mm to 10 mm. A commonly used support rod size range is between 3 mm and 6 mm. Thicker support rods, such as 8 mm or 10 mm, may be employed for applications with higher flow rates or when increased strength and load-bearing capacity are required.

Wedge wire panel working principle

Wedge wire panel working principle

Wedge wire panels operate on the principle of “cutting” or “slot” filtration. These panels consist of profiled wires welded onto support rods, creating narrow slots between the wires. When fluid flows through the panels, the slots allow the fluid to pass while retaining particles larger than the slot size. The filtration efficiency depends on the width of the slots, which is carefully designed to retain specific-sized particles.

One key advantage of wedge wire panels is their self-cleaning capability. The fluid flow helps wash away larger particles or debris retained on the panel’s surface, minimizing the risk of blockages. This design, coupled with the use of high-quality materials and welded construction, ensures the panels’ strength and durability.

Do you offer any specialized surface treatments for the panels?

Passivation: Passivation is a chemical treatment applied to stainless steel panels to improve corrosion resistance. It removes surface contaminants and forms a protective oxide layer, reducing the risk of corrosion.

Electro-polishing: Electro-polishing is an electrochemical process that smoothens the surface of the wedge wire panels. It can improve the panels’ cleanability, resistance to fouling, and overall surface finish.

Coatings: Certain coatings, such as epoxy or polymer coatings, can be applied to the wedge wire panels to provide additional corrosion resistance or specific functionalities like anti-fouling or anti-adhesive properties.

Anodizing: Anodizing is an electrochemical process commonly used on aluminum panels to create a protective layer of oxide. It enhances corrosion resistance and can provide improved aesthetics.

Wedge wire panel installation

Installing wedge wire panels involves several key steps to ensure a proper and effective installation.

First, prepare the installation area by cleaning it and removing any debris.

Next, construct a frame or support structure to securely hold the panels in place. Position the panels within the frame, ensuring proper alignment and fit.

Fasten the panels securely using appropriate fasteners and consider applying sealing materials or gaskets to prevent leaks. Once the panels are installed, conduct thorough testing to ensure proper functioning and make any necessary adjustments.

The open area of a wedge wire panel filter refers to the percentage of open space or voids within the filter media. It represents the amount of space available for fluid or gas to pass through the panel and is an important factor in determining the filtration efficiency and flow rate. The open area of a wedge wire panel filter can vary depending on factors such as the slot size, wire diameter, and the arrangement of the wedge wires. Typically, the open area ranges from around 10% to 60%, but it can be customized based on specific filtration requirements.


A higher open area allows for increased flow rates and reduced pressure drop across the filter, which is beneficial in applications where maintaining high throughput is essential. However, a higher open area may result in reduced particle retention efficiency. Conversely, a lower open area provides higher particle retention capabilities but may lead to higher pressure drop and reduced flow rates.


The selection of the appropriate open area for a wedge wire panel filter depends on factors such as the desired filtration efficiency, the size and type of particles to be removed, the flow rate requirements, and the specific application needs. It is important to balance the open area with the filtration performance required for optimal filter operation.
