The modular system for our filter units is supplemented by metal filter elements. These are available in lengths of up to 900 mm. Existing systems can also be easily converted using the same screw thread in the filter plate. The metal elements are particularly suitable for high temperatures of up to 500 °C. They can be almost completely regenerated to their new state using a water bath or ultrasonic bath. The fineness of the filter fabric is adapted to the application. The metal fabric can be selected with a mesh size of up to 2 µm.
