Wedge Wire Cylinder

A Wedge Wire Cylinder (also known as Johnson screen cylinder, slotted tube, or profile wire cylinder) is a high-performance tubular filter element engineered by continuously welding V-shaped (wedge) profile wires onto longitudinal support rods. This precision-welded structure creates uniform, continuous slot openings, enabling efficient solid-liquid/gas separation, filtration, and sizing across demanding industrial environments. Renowned for high strength, accurate slot control, low clogging, and long service life, it serves as a critical component in self-cleaning filters, drum screens, screw presses, and water treatment systems.

Unmatched Features & Advantages
1. Anti-Clogging V-Profile Design: The internal-narrow, external-wide trapezoidal slots prevent particle trapping; impurities detach easily during backwashing, solving the clogging issue of traditional mesh screens.
2. Precision Filtration: Slot openings are controlled to ±0.03mm, ensuring accurate separation of particles as small as 20μm.
3. Superior Mechanical Strength: Fully welded structure withstands high pressure, vibration, and abrasion; no loose wires or deformation under heavy loads.
4. High Flow Efficiency: Large open area enables high flow rates with minimal pressure drop, reducing energy consumption.
5. Easy Maintenance & Reusability: Smooth surface allows quick cleaning via backflushing, scraping, or ultrasonic methods; reusable for long-term cost savings.
6. Long Service Life: Corrosion-resistant materials and robust construction deliver 3–5 times longer life than standard filter media.
