The extractor hood continues running at low speed for 10/15 minutes before
turning itself off altogether.
Will ventilate the kitchen at hourly intervals on the lowest fan setting for 24
hours a day.
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.
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.
Neff extractor hoods are exceptionally quiet. Our model
D99T7 has a maximum extraction rate of 650m
3/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 is achieved by insulating the
inside of the hood with special sound absorbing surfaces.
