Electrostatic precipitator for building ventilation systems.

摘要

An electrostatic filter according to the invention comprises an air duct, a cover (4) with an air inlet opening (5), first and second plate-shaped electrodes arranged in the air duct, corona wires (8) arranged in front of the second electrodes in the air duct and extending in a running direction (12). extend, clamping devices for tensioning the corona wires (8) and a first holder (10) and a second holder (11) for the clamping devices. The two brackets (10, 11) are mounted on side walls (3) of the air duct and electrically isolated from the side walls (3). The air inlet opening (5) of the cover (4) is dimensioned such that the corona wires (8) extend to the edge of the air inlet opening (5). Each of the corona wires (8) is associated with a tensioning device, which has at least one tensioning element,
