Filter Screens for Pharmacy and Chemical Industries
WEWIN Screen Gasket Company's filter discs are plain or twill woven by quality stainless steel wires, black iron wires or copper wires, and are cut into different diameters according to customers' request. And our discs can also be welded into multilayer filter discs in round, square, or rectangular shapes. The discs are mainly used in pharmacy and chemical industries to filter gas, liquid and oil. They have the advantages of acid-resisting, alkali-resisting and corrosion-resisting.
Filter discs with high mesh number can better stop the foreign particles into liquid or gas.
Multilayer spot welding filter discs have better filter function than general single layer filter discs.

Types of wire mesh filter discs:
Filter discs with large mesh hole can stop big foreign particles, then the filter discs with smaller mesh hole can stop the smaller particles.
Advantages:
Applications:
The filter discs, also filter meshes we produce are mainly used for solid-liquid separation, gas-liquid separation, or in industry of petroleum, chemical industry, chemical fiber spinning industry, metallurgy, pharmacy, ceramic, sewage treatment, food and beverage, cosmetic, etc. And they are best suitable for liquid filtration, dry filtration and gas filtration.
Our filter discs can efficiently filter the suspension, particles, rust , dirt and other impurities in the tap water, industrial water, living water, electroplate liquid, chemical liquid and oil.
According to customers different request, we can produce filter discs to satisfy customers' specific demands.
Toroidal filter discs are used in special places, and the perforated discs inside them can protect the discs not to be destroyed by particles.
