Due to high airflow speeds at the outer edging, the WS9074M offers effective vapour extraction at low noise level in efficiency class A+. LED strips illuminate the hob well. The glass cover on the bottom is opened by use of telescopic springs; the stainless steel grease filters and carbon filter can be cleaned in the dishwasher. The black glass with discrete metallic paint used for the front and the cover harmonises with modern kitchens.
