Expertise in the field of ventilation technology

Ventilation technology
Every Miele rangehood is tested in accordance with current European standards. The air throughput and sound performance data given in the product overviews are representative and comparative values. Miele is a member of CECED* (European Association of Household Appliance Manufacturers). All of its members have signed up to a voluntary agreement to measure air and sound performance values in accordance with relevant European standards and to only publish 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 rangehood 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).
Silencer - for greater peace and quiet
Many Miele rangehoods have highly efficient sound proofing as standard which make them very quiet in operation. Should you wish to have an even quieter working environment, the Miele DASD 150 silencer is available as an optional accessory. It will reduce noise levels by up to 4.5 dB(A) re1pW. It can be fitted in a variety of positions. Suitable for use with a range of extraction as well as recirculation mode rangehoods.
Wall vent
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.
Ventilation ducting
Extraction ducting expels odours, moisture and heat to the outside. The extraction performance and noise levels of the rangehood 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.
