Structural Features

► V-Shaped Wire Winding Design. The filter surface is wound with trapezoidal (wedge-shaped) stainless steel wire, welded to longitudinal support rods at every intersection, forming continuous and uniform V-shaped slots. This design allows particles to be retained only at the two contact points, preventing clogging and allowing easy release of contaminants during backwashing.

► Conical Structure Advantage. The tapered transition from 37mm at the top to 90mm at the bottom accommodates specific housing structures, optimizing fluid distribution while maintaining filtration area. Conical wedge wire filter cartridges offer unique advantages in centrifugal separation and applications requiring variable-diameter installation.

► High Structural Strength. Fully welded integral construction — the wound wire is connected to all longitudinal support rods via resistance welding, capable of withstanding high working pressure differentials and pulsating pressures.

Performance Advantages

1. High Flow Capacity: The V-shaped slot design provides a larger effective flow area compared to bridge-type or slotted filter tubes, significantly improving flow efficiency.

2. Excellent Self-Cleaning: The smooth wedge-shaped surface prevents particles from embedding into slots, enabling efficient backwashing, extended service life, and reusability.

3. Corrosion & Heat Resistance: Available in stainless steel materials including 304, 316L, etc., suitable for various corrosive media and high-temperature conditions.

4. Precision Control: Slot dimensions can be precisely controlled to ±0.005mm level, meeting fine filtration requirements.

Applications

Conical wedge wire filter cartridges are widely used in the following fields:

► Water Treatment: Automatic backwash filters, groundwater sand control, wastewater treatment, ion exchange resin retention.
► Petrochemical: Catalytic reactor internals, hydrodesulfurization, oil & gas well sand screen tubes.
► Food & Beverage: Sugar liquor filtration, beer clarification, starch separation.
► Mining & Metallurgy: Slurry dewatering, tailings filtration, coal washing.

Working Principle

Filtration Principle (Outside‑In Flow, the most common configuration)

The wedge wires are oriented with their wider face facing outward and the narrower face inward. This means that each slot between two adjacent wires has a V‑shaped cross‑section that widens toward the inside — the narrowest gap is at the outer surface, and the passage becomes wider as the fluid moves inward.

Filtration: Liquid passes through the screen from the outside to the inside. Solid particles larger than the slot width are retained on the outer surface at the very point of entry. Because the slot opening is the narrowest point, particles are unable to pass through, and they do not become wedged deep inside the slot.
Non‑Blinding and Easy Cleaning: Since the trapped particles make only point contact with the surface, they do not lock themselves into the screen. This gives the wedge wire filter element its characteristic non‑blinding behaviour. During backwashing (reverse flow from inside to outside), the wider internal passage releases the particles effortlessly, quickly restoring the clean pressure drop.
Filtration Rating: The width of the continuous slot (ranging from as fine as 25–50 microns up to several millimetres) defines the absolute filtration rating. The rigid all‑welded construction ensures the slot remains constant under high differential pressure.

Reverse Flow Configuration

In some designs, flow is from inside to outside. The wedge wires are then oriented with the wide face inward. The principle remains the same: the narrowest point of the V‑shaped slot faces the incoming fluid, capturing particles on the inner surface and making the element just as easy to clean.

In summary, the wedge wire filter element combines precise slot geometry with a V‑shaped opening, delivering surface filtration that is exceptionally resistant to clogging and highly effective for high‑pressure, high‑temperature, or heavy‑duty solid‑liquid separation applications.

FAQ

Q1:What is the advantage of a wedge wire structure compared to mesh filters?

A1:Wedge wire filters provide a non-clogging V-shaped profile, which reduces blockage risk and improves flow efficiency compared to traditional woven mesh filters. It also offers higher mechanical strength and longer service life.

Q2: Can the size or mesh be customized?

A2: Yes. We support customization of:

Diameter (OD)
Height/length
Mesh size (10–300 mesh available)
Connection type (flange, threaded, welded)
Material (304 / 316 / 316L / duplex stainless steel)

Q3: How is this filter manufactured?

A3: It is produced using precision wedge wire welding technology, where V-shaped stainless steel wires are welded onto support rods to form a rigid cylindrical filtration structure with uniform slot openings.
