219mm Johnson ScreenJohnson Screen mostly refers to V-Wire Water Well Screen or wedge well screen.
stainless steel Johnson screens are made from V shaped profile wire, which is spirally wound around longitudinal support rods. Each intersecting point of these wires is fusion welded, with an unique welding process. The pitch of winding gives different spacing or slots between two adjacent turns of wire. This spacing or slot gives passage for water to enter. The entire process is completed on fully computerized machines. Johnson screen /wedge well screen offers great strength, precision, long service life and a wide range of applications in the field of process and engineering such as sugar juice filtration, waste water treatment, crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation, filtration of oils, greases, paints, food products, water, fuels, liquid cooling agents, chemicals etc.
