The E636AH ventilator hood connects the extractor chamber with the outlet tower, so that they form one unit. The central filter is located further above and, together with the extractor chamber, generates a double negative pressure structure, which better captures the vapours and discharges them. This construction reduces the bends at the junction of the vapour cavity and the tower hood where the vapours must pass and makes cleaning easier. The black, hexagonal touch-operated user interface imparts to the hood a sculptural impression.
