The wedge wire screen parabolic panel sieve plate water filters are made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods. Each jointpoint of these wire is fusion welded, the V or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening. Therefore the screen allows water or oil to enter the well freely in ample quantities while keeps the majority of sand and gravel out of the well at the same time.
The wedge wire screen parabolic panel sieve plate water filter have continuous slot openings that widen inwardly. This makes the screen self-cleaning by allowing "near slot size" particles to pass through the screen rather than plug the opening. And the products are made by continuously winding a wrap wire onto a frame of support rods. This is done on precision built, electronically controlled machinery which ensures consistently high strength, precise slot openings and product durability.
