·About Filter Principle 

Bridge slot filter is made of isosceles triangular (or trapezoidal) cross section of the stainless steel wire spiral coil formed by the ring gap sand. The triangular vertices of the filaments are oriented toward the inside, thus forming an opening gap of a trapezoidal cross section, so that the sand is not easy to block the flow path, thus has a good sand control effect and a longer service life.

Wells are generally filled with wire-covered gravel packing. Its sand control mechanism is to use the sieve to block the gravel, gravel formed by the gravel to block the smaller formation sand.
