Advantages of

Stainless Steel Wedge Wire Screens

1. Better filter function. The V-shape section plane of water well screens (Johnson screens) creates the continuous slot, which can avoid blockages and make sure of the unimpeded water flow.
2. Prolonged well life..  The operational principle is that with the narrow approach side opening and an increasing gap behind the entry point clogging is reduced. The flow rate is reduced after the water passes the initial opening.

3.  Long service life. Wire and support rods are all-welded, which makes water well screens  
     (Johnson screens) more robust and results in a longer service life.

1. High pressure-resistant. The longitudinal support rods and the continuous slot make the screen better able to stand pressure.
2. Customized. Specifications and end connections of water well screens(Johnson type screens)

1. Can be fabricated according to customers' requirements.
