Advantages of Johnson Screen

1. Structural

Compared with woven mesh filter elements, Johnson screen filter products have inherent advantages in structure.

1) Self-supporting structure, high mechanical strength, no need for perforated tube, expanded metal tube, and other supporting materials.

2) The filter surface is of a V-shaped wire structure, and there are only two points of contact between impurities and the surface. Impurities are easy to clean and not clogged.

2. Opening rate

The best way to improve filtration efficiency and save energy (reduce pressure drop) is to increase the opening rate. The continuous slotted v-wire structure makes Johnson screen filter products have a high opening rate.
Increasing the hole diameter of the perforated mesh can improve the opening rate, but at the same time, it also loses the structural strength. Johnson screen is the perfect solution to replace the product.

3. Stable filtration efficiency

As the use time of the woven mesh filter and the sintered filter element increases, the filter material will be damaged, which will greatly reduce the filter efficiency and increase the operating cost of the filter system.
The gap is a continuous slotted structure, which maintains a stable filtration accuracy and ensures the effective retention of the filter medium.
