V-Wire Wrapped Filter Element Stainless Steel for Liquid Filtration and Backwashing
Product Spotlights
As a manufacturer with over 25 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality V-Wire Wrapped Filter Elements made of stainless steel for liquid filtration and backwashing applications. Our factory has an annual export value of US$5-10 million, serving markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. This V-Wire wrapped filter element is engineered to deliver reliable, efficient solid-liquid separation with easy backwash capability, reducing downtime and maintenance costs.
The V-Wire (wedge wire) construction provides a continuous slot opening that is self-cleaning during backwashing. The triangular profile wire creates a V-shaped slot that allows particles to be trapped on the surface rather than inside the media, making it ideal for applications requiring high flow rates and low pressure drop. The stainless steel material ensures excellent corrosion resistance, strength, and longevity even in harsh environments.
Key Features & Benefits
- High mechanical strength: The all-welded construction of V-wire and support rods provides robust structural integrity, allowing operation under high differential pressure.
- Precise filtration: Slot width is consistent along the entire element, ensuring stable filtration efficiency from 50 μm to 2 mm.
- Easy backwashing: Smooth surface and V-shaped slots release trapped solids quickly during backwash, minimizing water consumption and downtime.
- Corrosion resistance: Made from stainless steel 304 or 316L, suitable for aggressive liquids, seawater, and chemical solutions.
- Customizable dimensions: Length, diameter, connection type, and end caps can be tailored to your specific equipment.
- Long service life: No media replacement needed; the element can be cleaned and reused repeatedly.
- Wide temperature range: Can operate from cryogenic to high temperatures, depending on gasket material.

Why choose our V-Wire Filter Element? Compared to traditional mesh or sintered filters, the wedge wire design offers superior backwash efficiency, higher dirt holding capacity, and longer operational cycles. The smooth surface prevents particle embedding, making cleaning fast and thorough. Our stainless steel elements are widely used in water treatment, petrochemical, food & beverage, pharmaceutical, and mining industries.
Frequently Asked Questions (FAQ)
-
Q: What is the difference between V-Wire and conventional wire mesh filters?
A: V-Wire (wedge wire) uses a continuous triangular profile wire wrapped around support rods, creating a V-shaped slot that prevents clogging and allows easy backwashing. Mesh filters tend to trap particles inside the weave, making cleaning difficult. -
Q: Can this filter element be used for backwashing systems?
A: Yes, this element is specifically designed for both forward filtration and backwashing. The V-slot geometry releases trapped solids quickly during reverse flow. -
Q: What stainless steel grades are available?
A: We offer SS304 and SS316L as standard. Other alloys like duplex stainless steel can be provided upon request for highly corrosive environments. -
Q: How do I determine the correct slot size for my application?
A: Slot size depends on the particle size you want to remove. We recommend providing a sieve analysis of the feed slurry. Our engineers can help you select the optimal slot opening. -
Q: What is the typical lead time for custom orders?
A: For standard dimensions, lead time is 15-20 days. For fully customized elements, it may be 20-30 days depending on complexity. -
Q: Do you offer samples for testing?
A: Yes, we can provide small samples or pilot-scale elements for on-site testing. Please contact our sales team with your requirements. -
Q: Can the element be repaired if damaged?
A: Typically, if the V-wire is damaged, the entire element needs replacement. However, our robust construction minimizes risk of damage. We also offer spare parts for end caps and connections. -
Q: What is the maximum pressure drop allowed?
A: This depends on the specific design. Standard elements can handle up to 2.5 MPa differential pressure. For higher pressure applications, we can reinforce the structure.
