Dorstener Drahtwerke is your single source manufacturer for high-quality, welded wire mesh, woven wire cloth, sintered wire cloth, and metallic filtration products. Our product range includes also filters and screens for various applications in industry, medical technology and construction.

• Electrostatic oil and emulsion mist separator / Electrostatic extraction system for separating oil mist, emulsion mist, oil smoke, welding smoke, fumes, suspended particles, oxide-containing smoke and aerosols.
• Mechanical air filter for separating emulsion mist, oil smoke, vapor, suspended particles, oxide-containing smoke, aerosols, etc.
• Dust filters from simple pocket shaker filters to large cartridge filters.
• Wet separators for problematic dusts, be they sticky, moist, flammable or explosive.
• Filter media for the filtration of impurities from liquids such as grinding emulsion, drilling emulsion, eroding oils, acids, alkalis, etc.
• Customized special systems such as: cyclone separators, wet separators, adapted intake and outlet collectors, activated carbon filters, filter systems for extrusion coating, etc.

Our core competences lie in construction, production and installation of filtration solutions for different sorts of fluids, especially oils and water. The engineering, manufacturing and forming of fluid dynamic housings are all located under one roof.
Major advancements of our suction filter housings are the modular design and a highly detailed production depth. This enables us to meet and create highly individual requirements and options.

• Ink industries
• Food industries
• Automobile industries
• Laundry facilities
• Aluminium plants
• Pickling plants
• Paper industries
• Tire industries
• Communal and public services
• Chemical industries

Diffusion dialysis is a membrane separation process used to regenerate acids or bases or to replace special ions in a solution (“anion/cation exchange”).
The process is based on two different fluids flowing through two channels which are separated by a semi-permeable membrane.
In a simplified way, mass transport occurs from concentrated to diluted fluids until the concentration difference has been balanced out. With a selective membrane, certain components can be "separated out" from the concentrated fluid by increasing the resistance for other components.

Of the more than 200 employees at our Olfen site in Westphalia, 35 engineers and technicians alone provide the development and construction of bespoke conveyor systems and special machinery with regard to design, manufacture and sales. NSM support its internationally operating customers in many product areas as a market and technology leader with trend-setting and reliable automation systems. On a production area exceeding 10,000 m² the plants are installed and tested, before they leave our premises to be installed and commissioned worldwide. A fast supply of replacement parts as well as competent and experienced service technicians secure the fastest competent support in case of an emergency.

The filter usually consists of cartridge shell, filter element, blowdown part, transmission device and electrical control part, the impurities in the fluid are removed by the filter element blocking. We have rich OEM experience and capability.

Small size: 0.2～10mm; general size: 10～800mm; large size to 8000mm

Where pure gases/liquids are used in many areas, filtration of the gas/liquid is often required to ensure proper use.

A filter is a device used to remove solid impurities from liquids or gases. It usually
consists of a housing, a filter element, and other accessories.

The filter is made of metal knitted wire mesh that is coiled and put into extrusion molds to form cylindrical shapes, and different densities are adjusted to meet the requirements of the filter.
