Anping County Boli Hardware Wiremesh Products Factory, with over 25 years of manufacturing experience since 1998, presents our premium Stainless Steel Wedge Filter for Water Treatment. This filter features a precise 0.5mm slot opening, constructed from high-quality 304 stainless steel, and comes with a standard 2" NPT connection for easy integration into existing piping systems. Designed for efficient solid-liquid separation, our wedge filter offers superior durability, clog resistance, and consistent performance across various water treatment applications.
Our wedge wire filters are manufactured using advanced continuous slot winding technology, ensuring each slot is uniform and precise. The V-shaped profile of the wedge wire allows for self-cleaning during backwashing, significantly reducing maintenance downtime. Below are the key technical specifications:

| Slot Opening | 0.5 mm (can be customized from 0.1mm to 3mm) |
| Connection | 2" NPT Male/Female (other sizes available) |
| Diameter | Standard: 2" to 12" (custom sizes upon request) |
| Length | Customizable, typical up to 3000mm |
| Pressure Rating | Up to 10 bar (higher pressure ratings available on request) |
| Operating Temperature | -20°C to 400°C |
| Surface Finish | Pickled, passivated, or electro-polished |
Product Features & Benefits:
- High Mechanical Strength: The wedge wire construction provides exceptional structural integrity, capable of handling high differential pressures and backwash flows.
- Clog-Resistant Design: The V-shaped slot profile allows particles to pass through smoothly, minimizing blinding and enabling efficient backwashing.
- Corrosion Resistance: 304 stainless steel offers excellent resistance to most water-based chemicals, chlorides, and acidic environments, ensuring long service life.
- Precise Filtration: Each slot is continuously wound with CNC-controlled tension, guaranteeing a uniform 0.5mm opening (±0.03mm tolerance) for consistent filtration.
- Easy Installation: The 2" NPT connection allows direct threading into standard pipes, reducing installation time and cost.
- Customizable Dimensions: We offer tailored diameters, lengths, end connections (flanged, threaded, or plain), and slot sizes to meet specific project requirements.
- Low Maintenance: The self-cleaning nature of the wedge wire reduces the need for manual cleaning, lowering operational costs.
Applications:
- Raw water intake filtration (surface water, groundwater)
- Industrial process water treatment
- Cooling tower water filtration
- Wastewater treatment – primary and tertiary filtration
- Fish farming and aquaculture water intake
- Desalination pre-filtration

Frequently Asked Questions (FAQ)
-
What is the difference between a wedge wire filter and a wire mesh filter?
Wedge wire filters have a V-shaped profile that creates a continuous slot, providing higher strength, precise slot opening, and self-cleaning capability. Wire mesh filters are woven and can clog more easily; wedge wire is preferred for demanding water treatment applications. -
Can the slot size be customized other than 0.5mm?
Yes, we offer slot openings from 0.1mm up to 3mm. Please specify your required filtration micron when ordering. -
Is this filter suitable for seawater or high-chloride environments?
For standard 304 stainless steel, it is suitable for freshwater and low-chloride environments. For seawater or high-chloride application, we recommend 316L stainless steel or duplex stainless steel – available upon request. -
What end connections are available besides 2" NPT?
We can provide flanged connections (ANSI, DIN, JIS), grooved ends, plain ends for welding, or other NPT sizes. Please consult with our sales team. -
How do I clean the wedge filter?
The design allows for easy backwashing with water or air. For stubborn debris, chemical cleaning or manual brushing can be performed. The robust construction withstands repeated cleaning cycles. -
What is the maximum length you can produce?
Typical maximum length is 3000mm, but longer filters can be manufactured for special projects. Contact us for custom lengths. -
Do you provide samples for testing?
Yes, we offer small samples for evaluation. Please pay shipping costs; the sample is free. We can also arrange a trial order for a short filter section. -
What is the lead time for mass production?
For standard sizes, lead time is 15–20 working days. Custom orders typically require 25–30 working days, depending on complexity.
