Performance of heavy duty filter screens in fluid filtration

Metal screen and Super Metal Screen filters are made from stainless steel wire cloth offering perfect particle removal efficiency. The super metal screens incorporate a filter media made from weaving fine wires. A unique structure is developed by sintering and calendaring the metal mesh to develop a highly resistant pure metal bond at every wire to wire contact point. It develops a depth media. Super metal screen cartridges provide high porosity and particle removable efficiency at low micron ratings. Every metal screen includes a wire mesh sintered to either side of the filter media to support and strengthen it.

The metal screen filter cartridges made from a woven metal screen media comprising of stainless steel wires of a specific size. Meal screen rating is determined by the weaving process, the wire spacing and wire diameter used.

The heavy duty tungsten mesh screen filters are particularly developed by 3M purification for fluid filtration with wide range of characteristics such as high viscosity, high temperature, high purity and corrosive characteristics.

Super Metal screen cartridges can be used for special applications that desire specific parameters like:

·         Specific diameters and lengths

·         Higher differential pressures than standard

·         Special corrosion resistant materials such as Hastelloy wire mesh and Inconel mesh

The mesh screens are developed to particular codes for various industrial activities like aeronautics, nuclear power, pharmaceuticals, chemicals and food processing.

Our Super Metal filter screens are made under extreme quality control during production. The filter cartridges undergo integrity testing to verify their pore ratings.

The screens are easy to clean by using different types of methods such as back flushing, chemical cleaning and ultrasonic cleaning. The woven wire screens are fit for use among many and diverse industries such as:

·         Nuclear

·         Pharmaceutical

·         Food Processing

·         Oil and Gas

·         Paints and Resins

You should understand that the core of every filter is the mesh screen element. To a large level, they decide the efficiency. The filters are made by using the best filter elements that meet the highest standards considering stability, long life and cleanability.

Surface filtration

Particles are basically separated at the surface of filter material. As soon as pre-set pressure drop is achieved, the filter materials are cleaned and the filtration process continues regularly or intermittently.

Depth filtration

The operating fluid cleaned penetrates the filter structure. The contaminating particles are held in the deeper layers of the filter. The flow resistance increases with more clogging of the media that the filter element should be replaced.
