Product Overview
The Slot Separator Scraper Filter Screen, also known as a wedge wire screen or Johnson screen, is a precision-engineered filtration component used in industries such as municipal water treatment, mining, food processing, and petrochemicals. The V-shaped wire profile creates a continuous slot opening that minimizes clogging and maximizes flow capacity. The scraper design ensures self-cleaning action, making it ideal for high-viscosity or fibrous materials.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a slot separator screen and a regular mesh screen?
A: A slot separator screen uses V-shaped wedge wire that creates precise slot openings, offering higher strength, less clogging, and longer service life compared to woven wire mesh. It is ideal for applications requiring consistent particle size separation. -
Q: Can I order a custom slot width not listed (e.g., 0.3mm or 4.0mm)?
A: Yes, we can manufacture custom slot widths from 0.1mm to 10mm, subject to tooling and production lead time. Contact our technical team with your requirements. -
Q: Is the screen suitable for acidic or alkaline environments?
A: 304 stainless steel offers good resistance to many corrosive media. For highly acidic or chloride-rich environments, we recommend 316L or 904L stainless steel, which we can supply on request. -
Q: What is the typical lead time for standard screens?
A: For standard sizes and slot widths, lead time is 15-20 working days. Custom orders may require 25-30 days depending on complexity. -
Q: Do you provide samples for testing?
A: Yes, we offer free sample pieces (e.g., 200mm × 200mm) for evaluation. Only shipping cost needs to be covered. -
Q: How does the scraper design help in cleaning?
A: The scraper edge is integrated into the screen surface, allowing moving blades or brushes to slide along the screen, dislodging trapped particles without damaging the wires. This reduces manual cleaning frequency. -
Q: Can the screen be used in a vibrating sifter?
A: Absolutely. Our screens are designed to withstand vibratory motion. We can add reinforcing ribs or custom edge profiles to fit your sifter frame. -
Q: What quality standards do you follow?
A: Our production adheres to international filtration industry standards, including dimensional tolerances per ISO 2768. We perform slot width inspection and material certification upon request.
