Air extraction/recirculationMost Gaggenau ventilator hoods can be used both for air extraction and recirculation. In the extraction function, cooking fumes are released outside either directly or via a ventilation duct. In the recirculation function, a built-in active charcoal filter absorbs kitchen steam. In both cases the air, which is saturated with grease and odor particles, first passes through a grease filter. This prevents the inside of the hood and the exhaust air ducts from becoming coated with deposits. The circulating air version, in which no air is released outside, absorbs odor particles with an additional, active charcoal filter. This needs replacing about twice a year – a simple operation with all Gaggenau ventilation appliances.
Grease filter saturation indicator
For ease of hood maintenance. A blinking light on the control panel acts as a reminder that the grease filter is due for cleaning. Soiled filters are less effective and increase noise levels in the hood.
Intensive mode
Three power settings and an additional intensive mode can be activated via individual control buttons (rotary knobs on the AH 600 and the AH 360). The intensive mode automatically switches back to the previously selected setting after three, five or ten minutes’ running, depending on the model – which is very practical, especially after searing meat.
Interval ventilation
When this feature is activated, the extractor hood automatically switches to the pre-selected power setting for five minutes during each hour, allowing the room to be regularly supplied with fresh air, even when vacated for long periods. It is also ideal when the room needs plenty of ventilation overnight, for example after a big party in the kitchen.
Delayed shut-off
This function allows one to set the ventilation to stay on for a further ten minutes after use on any setting, before automatically switching itself off. This way, the air is cleaned especially thoroughly after cooking.
Soft-light
The soft-light illumination of the cooking zones automatically goes on and off gradually, and can be dimmed manually from bright illumination of the cooking zones to atmospheric background lighting.
Stainless steel grease filter
With Gaggenau ventilator hoods, the saturated air with grease and odor particles first passes through a grease filter. This prevents the inside of the hood and the exhaust air ducts from becoming coated. The stainless steel filter can be easily removed and cleaned in the dishwasher.
