Johnson filter for water well

Introduction of  Johnson filter for water well

1.Johnson filter  consist of Vshape profile wire and the longitudinal support rods.
2. Each intersecting point of wires of  Johnson filter is fusion welded,  so it has sturdy  construction and good  mechanical property.
3. The Vshape section plane of  Johnson filter can avoid blockage, and make sure of the unimpeded water.
4. The consecutive slot of our  Johnson filter  have more open area , and  Johnson filter can reduce the speed  of the water entering to avoid the sand entering the screen under the great pressure, so it can filter sand better.
 5. The slot can change according to the real condition of the earth.
