Filter Screens for Pharmacy and Chemical Industries

Boegger Industech Limited 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.

Five filter discs with different mesh counts and the two smallest have metallic margins, three don't have margin.

Filter discs with high mesh number can better stop the foreign particles into liquid or gas.

wo small filter discs on a large multilayer filter disc which has several welding spots on the margin.

Multilayer spot welding filter discs have better filter function than general single layer filter discs.

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.

One irregular filter disc with seven welding spots on the margin.

According to customers different request, we can produce filter discs to satisfy customers' specific demands.

Eight toroidal filter discs with metallic margins and they are all one perforated disc within two woven meshes.

Toroidal filter discs are used in special places, and the perforated discs inside them can protect the discs not to be destroyed by particles.
