ohnson Screen are made from V shaped profile wire, which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded, with an unique welding process. This spacing gives passage for water to enter. The entire process is completed on fully computerized machines. The pitch of winding gives different spacing between two adjacent turns of wire. 

Johnson screen have the features of great strength, precision, long service life and a wide range of applications in the field of process and engineering such as waste water treatment, sugar juice filtration, crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation, filtration of oils, greases, water, fuels, paints, food products, liquid cooling agents, and chemicals etc.

 Johnson screens , is the highest filtering precision Filtering screen elements which made by Mechanical Control Engineering. To make the screens,  The tools should be prepared according to the request of screens diameter and the requests for support rods numbers. 

The profile wire is a kind of special stainless steel wire. The shape is triangle, V shape. The wire has a name ,Wedge Wire. The screens made of this kind of wire is called wedge wire screens.  

By using this johnson screen, The screen filter element has a unique structure. The Vee Filtering Slot makes the screen high effciancy Filtering ability. And the back flushing cleaning is also available. So such screens are more and more used in Automatic Filtering system as immportant filtering element.
