Features of Wedge Wire Screen / Johnson Screen


1. Less Clogging, Good Dewatering

The " triangle shape," which is the biggest feature of the Wedge Wire Screen, means that as solids pass through, the contact points are small and the tips of the slits are widened, such that solids are less likely to clog, and even they do clog, there is a strong backwashing effect, resulting in excellent maintainability.

2.Stronger Structure, High Durability 

1).Screen formation with wire diameter larger than the slit is possible.
2).Because the screen surface is smooth, the degree of wear is constant.
3).The standard material is stainless steel (SUS304, 316L).
Therefore, Wedge Wire Screen feature higher strength and durability than filters such as wire mesh, perforated plates or filter cloths, and depending on the usage environment and material, they can be used almost indefinitely without replacement, reducing running costs. In addition, we are also able to produce Wedge Wire Screen using special materials such as titanium or duplex stainless steel.

3. Broad Flexibility in design 

Because many processing variations are possible, Wedge Wire Screen can be manufactured in various shapes such as flat, cylindrical or conical.
