Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in wire mesh and filtration products. With over 25 years of experience and an annual export value of US$5-10 million, we supply high-quality filtration solutions to global markets including North America, Europe, Asia, and Oceania. Our 18° wedge wire filter sector for disc vacuum filters is engineered to deliver precise solid-liquid separation with a 0.2mm slot opening, made from durable 304 stainless steel. This product combines robust construction with excellent flow characteristics, ensuring reliable performance in demanding industrial applications.
Product Overview
The 18° wedge wire filter sector is a critical component for disc vacuum filters used in mining, chemical processing, water treatment, and food industries. Its unique wedge wire profile provides a self-cleaning effect, reducing blinding and extending service life. The 0.2mm slot width offers high filtration accuracy while maintaining excellent throughput. Manufactured from 304 stainless steel, it resists corrosion and wear, making it suitable for both acidic and alkaline slurries.
Key Features & Benefits
- Precision Wedge Wire Design: Continuous V-shaped wire profile ensures uniform slot width (0.2mm) and minimizes particle clogging.
- High Open Area: Up to 60% open area allows efficient liquid passage, reducing energy consumption and improving filtration rates.
- 304 Stainless Steel Construction: Excellent corrosion resistance and mechanical strength, suitable for harsh environments.
- 18° Sector Shape: Optimized for standard disc vacuum filter segments, easy to install and replace.
- Self-Cleaning Capability: The wedge shape promotes backwashing, reducing maintenance downtime.
- Customizable Dimensions: Available in various radii, thicknesses, and connection types upon request.

Detailed Description
Our wedge wire filter sector is manufactured using advanced winding technology, where stainless steel wires are precision-wound onto support rods to form a continuous slot. The 18° sector shape is designed to match most disc vacuum filter segments, ensuring a tight fit and optimal sealing. The 0.2mm slot width is ideal for fine particle retention, such as in mineral concentrates, chemical slurries, or wastewater sludge. The 304 stainless steel material provides excellent resistance to rust and chemical attack, extending the service life even in aggressive media. Compared to traditional woven wire screens, wedge wire screens offer higher strength, longer lifespan, and easier cleaning. They are also less prone to blinding, which improves filtration efficiency and reduces labor costs. Our factory has been producing wedge wire screens since 1998, and we have shipped millions of sectors to customers worldwide. We can also customize the sector radius, thickness, and connection type (bolt, clamp, or welded) to fit specific filter models.

Frequently Asked Questions
1. What is the difference between wedge wire and woven wire screens?
Wedge wire screens have continuous V-shaped slots that are more precise and less prone to clogging. They offer higher strength and longer lifespan compared to woven wire screens, especially in heavy-duty applications like disc vacuum filters.
2. Can this filter sector be used for other types of filters?
Our 18° sector is specifically designed for disc vacuum filters. However, we can customize the angle, radius, and connection to fit other filter types (e.g., drum filters, centrifugal screens) upon request.
3. What is the maximum operating pressure for this sector?
The wedge wire structure is robust, but the sector is typically used under vacuum (negative pressure) in disc filters. For positive pressure applications, please consult our technical team for a suitable design.
4. Is the 0.2mm slot available in other materials?
Yes, we can manufacture the sector in 316 stainless steel, duplex stainless steel, or other alloys upon request. Please contact us with your specific requirements.
5. How do I clean the filter sector?
The wedge wire profile allows for effective backwashing. For stubborn deposits, we recommend using a high-pressure water jet or mild chemical cleaning. Avoid abrasive tools to prevent damage to the slot edges.
6. What is the typical lead time?
For standard sizes, lead time is 15-20 working days. Custom orders may require 25-30 days depending on complexity. We offer expedited shipping for urgent needs.
7. Do you provide samples for testing?
Yes, we can provide sample sectors for evaluation. Please contact our sales team to discuss sample availability and shipping costs.
8. How do I ensure the sector fits my existing disc filter?
Please provide the radius, sector angle, thickness, and mounting hole pattern. We can also work from a drawing or existing sample to ensure a perfect fit.
