    摘要: The invention relates to a filtering device with a filter housing which can accept a filter mat, is covered with a lamella grid on the outlet side and is fitted in an aperture in a mounting wall. RF screening is attained without altering the structure of the filtering device in that the surface of the filter housing is electrically conductive and inserted in the aperture in the mounting plate via an electrically conductive contact frame. The contact frame is electrically connected to the filter housing and the aperture in the mounting plate and there is an electrically conductive screening grid inserted or mounted in the filter housing or between the latter and a fan which can be linked thereto.

    摘要: An improvement to an air-water heat exchanger having an exchanger unit and a blower that are located in a housing constructed of a shell surrounded by a hood that is connected to a cabinet wall where the cabinet wall and the floor of the shell include openings and the housing is divided by at least one separating wall into an inlet chamber and an outlet chamber that connect to the openings in the floor of the shell. The improvement involves a blower, having an air outlet, that is located in the inlet chamber of the heat exchanger in such a manner so as to draw air through an air suction opening in the floor of the shell, and then supply that air through an opening in the separating wall to the exchanger unit located in the outlet chamber where the air is cooled and then directed by a drip separator and a baffle plate toward the associated air outlet opening in the floor of the shell.
