Anping County Boli Hardware Wiremesh Products Factory, established in 1998, has been a dedicated manufacturer of wire mesh and filtration products for over two decades. With annual export value between US$5 million and US$10 million, we serve clients across North America, South America, Europe, Asia, Africa, and Oceania. Our Stainless Steel Wedge Filter with 0.1mm Slot Width and 1" BSP Thread is a precision-engineered solution designed for demanding solid-liquid separation applications. Made from high-quality 304 stainless steel, this filter offers excellent corrosion resistance, mechanical strength, and long service life. The wedge wire construction ensures non-clogging operation and easy backwashing, making it ideal for water treatment, petrochemical, food processing, and mining industries.
Our wedge filters are manufactured using advanced wedge wire winding technology, where each wire is precision-welded onto support rods to create a continuous slot with precise opening. The V-shaped wire profile (wider on the inside, narrower on the outside) provides a unique self-cleaning effect and minimizes particle entrapment. The 0.1mm slot width offers high filtration accuracy while maintaining excellent flow rates. The 1" BSP male thread connection allows for easy installation into standard piping systems.
Key Features & Benefits:
- High Precision Filtration: 0.1mm slot width ensures reliable removal of particles down to 100 microns.
- Non-Clogging Design: V-shaped wedge wire prevents particles from bridging across slots, reducing maintenance frequency.
- Excellent Backwashability: Smooth inner surface allows easy cleaning with reverse flow, prolonging operational life.
- Corrosion Resistance: 304 stainless steel withstands aggressive fluids and harsh environments.
- High Mechanical Strength: Welded construction can withstand high pressure and temperature variations.
- Customizable Dimensions: Available in various lengths, diameters, and connection types to fit your system.
- Cost-Effective: Long service life reduces replacement frequency and total cost of ownership.

Frequently Asked Questions
Q1: What is the difference between wedge wire filter and conventional wire mesh filter?
A: Wedge wire filters use a V-shaped profile wire wound around support rods, creating a continuous slot that is wider on the inside. This design minimizes particle wedging and allows easy backwashing, while conventional mesh tends to clog due to its square openings. Wedge filters offer higher strength and longer service life.
Q2: Can I use this filter for high-temperature fluids?
A: Yes, 304 stainless steel can withstand temperatures up to 450°C (842°F) in continuous service. However, please note that the actual temperature limit depends on the sealing method and pressure conditions. For extreme temperatures, we recommend consulting our technical team.
Q3: Is the 1" BSP thread compatible with NPT threads?
A: BSP and NPT threads have different thread angles and pitches. BSP threads are parallel (BSPP) or tapered (BSPT), while NPT is tapered. Direct connection may cause leakage. We can produce filters with NPT or other thread types upon request.
Q4: How do I clean the wedge filter?
A: The filter can be cleaned by backwashing (reverse flow), chemical cleaning, or mechanical brushing. The smooth inner surface and V-shaped slots make cleaning easy. For heavy fouling, soak in acidic or alkaline solution as appropriate for the contaminant.
Q5: What is the typical pressure drop across the filter?
A: Pressure drop depends on slot width, flow rate, fluid viscosity, and contaminant load. For water at 1 m/s flow velocity, the clean pressure drop is approximately 0.2-0.5 bar. Actual values can be calculated based on your system parameters.
Q6: Can I customize the length and diameter of the filter?
A: Absolutely. We offer custom dimensions to fit your vessel or pipe system. Minimum order quantity may apply for non-standard sizes. Please provide your required outer diameter, length, and connection type for a custom quotation.
Q7: Is the filter suitable for drinking water applications?
A: 304 stainless steel is food-grade and safe for potable water. However, we recommend specifying food-grade surface finish (mirror polish) and confirming compliance with local drinking water standards. We can also supply 316L stainless steel for higher corrosion resistance.
Q8: What is the warranty period?
A: We provide a standard warranty of 12 months from the date of shipment against manufacturing defects. For high-volume orders, extended warranty can be negotiated. We stand behind the quality of our products and offer technical support throughout the product's life.
