Product Overview

Our Stainless Steel Wedge Wire Screen Cylinder is designed to provide reliable filtration in the most demanding environments. By precisely controlling the gap width, we offer solutions ranging from microfiltration to coarse screening. Each cylinder is manufactured using unique computer-controlled machinery, where a continuous length of triangular-section stainless steel profile wire is fusion-welded to internal support ribs.

This construction creates a rigid, one-piece structure with a smooth, continuous slot opening. Its superior anti-clogging performance makes it an essential filter element for self-cleaning filters and microfiltration equipment, particularly where corrosive media (acids, alkalis) or high temperatures are present.

Key Advantages

Controllable Filtration Precision: Gap widths can be tailored to meet specific filtration requirements, ensuring accurate particle classification.
Non-Clogging Geometry: The “V” shaped profile prevents impurities from getting stuck, as the opening widens inwardly to allow particles to pass or be flushed away.
High Structural Stiffness: Fusion-welding of wire to support bars creates a robust filter tube that resists deformation under high working pressures.
Thermal & Chemical Stability: Ideal for harsh environments involving high temperatures, organic solvents, and corrosive agents.
Optimal Open Area: The back width of the sieve strip determines a high aperture ratio, ensuring maximum flow with minimum pressure drop.

FAQ

Q: Can you manufacture screen cylinders with extremely fine gaps for microfiltration?
A: Yes, our advanced machinery allows for a minimum sieve gap of 0.02 mm, providing ultra-precision filtration for chemical and pharmaceutical applications.
A: The V-shaped wire only contacts particles at two points. Any particle passing through the surface gap will not get lodged because the slot widens inwardly, significantly reducing maintenance and downtime.
A: Absolutely. We can customize the diameter and number of support rods (e.g., 3.8mm/22 to 3.8mm/50) to meet the mechanical strength requirements of your specific application.
A: Yes, the smooth surface and non-clogging structure of our Johnson screens are specifically designed to facilitate efficient backwashing, making them ideal for self-cleaning filter systems.
