  • Apparatus for purifying air, in particular for ventilation and air-conditioning systems
    Patent number: 8157901
    Abstract: An apparatus for purifying air, in particular for ventilation and air-conditioning systems, has an air filter (11), which is inserted in an air channel (10) or in a filter wall for collecting dust. A dust agglomerator (12) with a DC voltage field is connected directly upstream of the air filter (11). In conventional filters, the efficiency is increased to such an extent that the dust throughput can be approximately halved. In addition, the initial efficiency is only insignificantly reduced during the operating time.
