Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of premium filtration components. Our 316L Stainless Steel Scraper Filter Element with 0.5mm Slot Width is engineered for demanding solid-liquid separation, combining the durability of Johnson wedge wire with a self-cleaning scraper design. This product delivers consistent flow rates, minimal pressure drop, and extended service life—ideal for industries requiring high-precision filtration.
Crafted from Grade 316L stainless steel, our filter element offers excellent corrosion resistance against chlorides, acids, and alkalis. The continuous slot (0.5 mm) is formed by precision-wound wedge wire, providing a robust V-shaped profile that prevents clogging and facilitates backwashing. The integrated scraper mechanism (optional) ensures effective removal of accumulated solids without interrupting filtration.
Key Features & Benefits
- High Strength & Durability: 316L stainless steel withstands high pressure (up to 10 bar) and temperature (up to 400°C).
- Precision Slot Width: 0.5 mm ± 0.05 mm ensures accurate particle retention.
- Self-Cleaning Capability: Optional scraper (manual or motorized) reduces downtime.
- Corrosion Resistant: Suitable for aggressive media in chemical, petrochemical, and marine applications.
- Easy Installation: Available with threaded, flanged, or custom end connections.
- Customizable Dimensions: Length, outer diameter, and slot width can be tailored per your process.

The scraper filter element is particularly effective in applications where sticky or fibrous solids need to be removed from liquids. For example, in the food and beverage industry (juice, beer, edible oil), petrochemical refining (catalyst recovery), and water treatment (sludge dewatering). The 0.5 mm slot width captures particles down to ~500 microns, making it suitable for coarse to medium filtration.
Our manufacturing process includes precision resistance welding of each wire intersection, ensuring structural integrity and uniform slot openings. Every filter element undergoes a hydrostatic pressure test and slot width gauge inspection before shipment. We offer surface finishing options such as pickling and passivation or electropolishing to enhance corrosion resistance and reduce fouling.
Frequently Asked Questions (FAQ)
1. What is the difference between a scraper filter element and a standard wedge wire screen?
A scraper filter element includes a moving scraper (manual or motorized) that runs along the screen surface to dislodge accumulated solids. This allows continuous filtration without stopping for backwashing, while a standard wedge wire screen typically requires periodic backwashing or manual cleaning.
2. Can the slot width be customized to a different size?
Yes, we offer slot widths ranging from 0.1 mm to 3 mm. The 0.5 mm width is a popular choice for general industrial filtration. Please contact us with your specific requirements for a custom quote.
3. Is the scraper mechanism included with the filter element?
The scraper assembly (blade, rod, and drive) is optional and can be supplied as a complete system. The filter element itself is the wedge wire screen; the scraper is a separate component that can be integrated. We can provide both as a matched set.
4. What types of end connections are available?
We offer threaded (NPT/BSP), flanged (ANSI/DIN/JIS), grooved, or plain ends for welding. Custom connections can be designed to match your existing piping.
5. How do I clean the filter element if I don’t use the scraper?
Without a scraper, the filter can be cleaned by backwashing (reverse flow), chemical cleaning, or manual brushing. The V-shaped wedge wire profile minimizes particle entrapment, making backwashing effective.
6. Is the material suitable for seawater applications?
Yes, 316L stainless steel offers excellent resistance to chloride-induced stress corrosion cracking. It is commonly used in desalination, offshore platforms, and marine filtration systems.
7. What is the typical lead time for a custom order?
For standard sizes (length up to 1500 mm), lead time is 10-15 working days. Custom dimensions or special scraper designs may require 20-25 working days. Our factory in Hengshui, Hebei, China, has been operating since 1998 with an annual export value of US$5-10 million, ensuring efficient production and timely delivery.
8. Do you provide samples for testing?
Yes, we can provide samples (e.g., 300 mm length) for evaluation. Please contact our sales team to discuss sample availability and shipping costs.
