The appropriate operating mode for every home
With intelligent technology, Miele can provide the optimum climate for every kitchen. There are two options for effective air filtration: extraction and recirculation. Both three operating methods have their strengths and limitations. A number of factors determine which is the best option for you.
Extracted air must be equalised by an additional supply of air in order for optimum hood function.
Extraction mode: the filtered air is directed out of the kitchen via ducting.
Extraction mode with an external motor:
The motor is installed outside to minimise noise.
Ducting of a minimum length of 5 - 7 meters is recommended.
Recirculation mode: cleaned air is redirected back into the room.
Regular ventilation necessary
The extraction system
Excellent efficiency and moisture extraction
Extraction mode rangehoods draw in the cooking vapours and filter out grease particles through the grease filters. The filtered air,
along with excess moisture and cooking odours, is then directed outside via extraction ducting. Extraction mode hoods require an opening
in the wall or roof for the ducting to vent outside. There must also be a supply of fresh air, e.g. through an open window.
- High air throughput
- Moisture is extracted to the outside
- External motor possible (noise reduction)
- Highly efficient
- No replacement filter costs
- Air throughput level is dependent on the type of ducting used and its diameter
- Cannot be installed everywhere
- Heat loss during cold spells
- Generally all types of cooktop (Induction, HiLight, Gas, CombiSet appliances) possible
- Gas cooktop - relies on a supply of oxygen for combustion
- Frequent use of deep-fat fryer, grill or wok - high temperatures and a great deal of grease and steam generated.
Extraction mode for external motor
Effective and very quiet
Extraction mode can be combined with an external motor which can be installed on an outside wall or a roof, reducing motor noise in the
kitchen to a minimum. A minimum ducting length of between 5 - 7 meters is recommended for significant noise reduction. Installation of
an external motor depends on the kitchen layout, the ducting and the rangehood.
Remotely locating the ceiling extractor motor
As an alternative to fitting an external motor, the standard motor supplied with the Miele ceiling extractor can be installed up to 185 cm
away from the ceiling extractor. Ducting which can be connected to a wall vent, for example, is fitted behind the motor.
If the distance between the ceiling extractor and the motor is greater than 185 cm,
the standard motor supplied must not be used, and the appliance must be connected to an external motor (e.g. an ABLG 202).
Recirculation mode
Simple and energy-efficient
Recirculation hoods draw in vapours, pass them through various layers of filtration and remove the grease and odour particles before returning
the clean air to the room. With this system air circulation occurs within a closed room. Recirculation hoods require neither ducting to the
outside, nor a wall or roof vent, making installation much easier and the only possibility for some locations (e.g. apartment blocks).
- Simple installation
- Building alterations are not necessary
- No energy loss: warm air (heating) or cool air (air conditioning)
remains in the room - Excellent performance
- Moisture generally remains in the room, making additional methods of air extraction necessary, e.g. an extraction fan.
- Active charcoal filter needs to be replaced regularly
- Electric cooktops
- An extraction mode hood should be installed where possible above gas cooktops as these generate large amounts of heat.
