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.
Claims14
Apparatus for air purification, in particular ventilation and air conditioning systems, having an air filter (11) arranged in an air duct (10) or in a filter wall for dust separation, in which a dust agglomerator (12) able to be provided with an electric voltage is connected upstream of the air filter (11), characterised wherein the dust agglomerator (12) exhibits a number of electrodes (16) and sheet metal plates (15) spaced from one another, in which the electrodes designed like wires (16) and the sheet metal plates (15) are each alternately arranged and a voltage, in particular a d.c. electric field is able to be generated with the electrodes (16).
Apparatus according to 1 characterised wherein the frame-like dust agglomerator (12) exhibits a depth of between 40 and 50 mm, so that it is suitable for being retro-fitted to an existing system.
