Johnson Screen

Slotted wedge wire screen filter cylinder are welded by profile V-wire and support wires, it is also called Johnson screen. It has large  filter area because of big opening, v wire structure are easy for automatic back washing and avoid pipe blocking. The pressure will be reduced when water flows in for greater filter area, avoid the grains of sand flow in the wedge wire tube in the high pressure conditions, so extend  the pipe's life.

With high-precision, our wedge wire filter elements are used in water treatment industry, oil filtration,paper making,refine sugar.
