FAQs
How do I stop the air from coming back into the room?

You need ducting with a wall outlet box and non return valve, which will stop the air returning. The larger the ducting, the less noise there'll be and the better the rate of extraction. We recommend at least 120mm diameter ducting (see accessories for ducting kits).

How can I get odours out more quickly?

Try switching on the extractor hood a few minutes before you start cooking. This starts to circulate air in the kitchen which will help remove the odours.

Do metal grease filters have to be changed?

They should be removed frequently for cleaning, and can be washed in the dishwasher. New grease and charcoal filters can be bought from a Neff dealer or our spares and accessories department - some hoods have an indicator to tell you when they need cleaning or replacing.


Functions
Automatic after running

The extractor hood continues running at low speed for 10/15 minutes before turning itself off altogether.
Internal operation
Will ventilate the kitchen at hourly intervals on the lowest fan setting for 24 hours a day.

Special sensor

An ultrasound sensor controls the hood. It detects the amount of steam and will automatically set the most effective setting for you to extract the unwanted steam and odours.

Intensive setting and Automatic revert

The intensive setting boosts the extraction rate to the maximum level and is intended to cope with particularly demanding cooking conditions. Intensive is normally only required for short periods of time therefore the hood will automatically revert back to power level 2 after approximately 10 minutes.

Noise level

Neff extractor hoods are exceptionally quiet. Our model D99T7 has a maximum extraction rate of 650m3/h and a noise level of just 54 decibels. By comparison a normal conversation is about 60 decibels. The amount of noise you hear will also be determined by the length and type of ducting and the surroundings it is fitted in. If you are sensitive to noise you should consider this when you plan and install your extractor hood.

Additional noise insulation

Additional noise insulation is achieved by insulating the inside of the hood with special sound absorbing surfaces.
