Reverse Back Wash Filter Drum Johnson Wire Screen Slot Cylinder 316l

Wire-wound Johnson Stainless Steel Well Screens For Filter Equipment is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. There is a fixed value slot between each V wire, and the continuous slot is designed to provide maximum open area to reduce entrance velocity, increase hydraulic efficiency and promote more effective development.

The slit size is accurate and the filtering precision is high. It has the advantages of strong structure, high ventilation efficiency, good heat dissipation, high temperature resistance, corrosion resistance, good mechanical properties, long service life, safe and reliable.

It has high strength, stiffness and bearing capacity, and can be used as a rigid screening filter for various shapes. This product is made of advanced fusion welding technology. The screen has the highest screening efficiency, the strongest anti-tensile capacity, the minimum maintenance requirement, and the longest service life.

We can also frame the arc-shape screen with polyurethane to strengthen its structure and make it have longer service time.
