Expertise in the field of ventilation technology

Ventilation technology
Every Miele cooker hood is tested in accordance with current European standards. The air throughput and sound emission data given in the product overviews are representative and comparative values. Miele is a member of CECED* (European Association of Household Appliance Manufacturers). All members have signed a voluntary agreement to measure air throughput and sound performance values in accordance with the relevant European standards and to publish only these figures in their sales literature. This transparency ensures that customers receive reliable performance data.
External fans
Fitting an external motor in the extraction system will help keep noise levels in the kitchen to a minimum. Here, the motor is installed externally, for instance on an outside wall, instead of in the hood. For a significant reduction in noise levels, the ducting system should be at least 5–7 m long. The motor and cooker hood are connected by a control cable. To implement this solution, Miele offers external motors for exterior walls (AWG 102*), roof installation (DGG 102) and wall installation (ABLG 202).
Silencers - for extra quietness
Many Miele cooker hoods have highly efficient sound proofing as a standard feature, which makes them very quiet during operation. Should you wish to have an even quieter working environment, the Miele DASD 150 silencer is available as an option It will reduce noise levels by up to 4.5 dB(A) re1pW. It even provides versatile options. It is suitable for use with extraction as well as recirculation mode cooker hoods.
Wall box
A wall vent kit can be fitted into an outside wall so that the air can be vented outside the building. Thermal bridges may occur in conventional wall vents, causing energy losses. For example, in winter cold air can enter the ducting.
Roof vent
If the extracted air is to be vented externally through the roof, a roof vent kit is required. Miele offers various models (DDF 125/150 or DDF 200) which are suitable for use with all roof pitches from 22° and all types of roof tiles. The high-quality stainless steel housing is secured with weatherproof lead flashing.
Flexible vent ducting
Extraction ducting expels odours, moisture and heat to the outside. The extraction performance and noise levels of the cooker hood depend greatly on the geometry and properties of the ducting system. Smooth round ducting or special ducting with a rectangular cross-section where the diameter is not reduced, is most suitable. Miele generally recommends a diameter of 150 mm. For hoods with a high extraction performance, a diameter of 200 mm is customary. Miele offers flexible aluminium ducting with shallow grooves. The DAS 150 and DAS 200 flexible aluminium ducting with a diameter of 150 and 200 mm fulfil the B1 fire prevention regulation requirements.
