Tips and advice

Engine sound​


A powerful motor has a greater extraction capacity, but also produces correspondingly more noise. You can reduce the noise by reducing the engine speed. It also reduces the air volume, but the lowest rise is good for most.
Air noise and duct noise

Air in motion causes noise. Just as when the wind rushes, sound is produced when it encounters an obstacle. The straighter - with as few bends and bends as possible - you can position your exhaust and the larger the channels the air is transported through, the less noise it will make.

In the case of ceiling integrated modell

You must be aware that the distance from the cooking zone to the filter surface is longer than normal. This type of model is usually equipped with edge suction, which increases efficiency. THERMEX recommends that the distance between the hob and the filter does not exceed 3 metres.


The optimal distance

THERMEX recommends that you mount your range at a height of 500-700 mm above your stove. However, always pay attention to applicable legal requirements and specifications for cookers and hoods.

Avoid loss of suction power

As far as possible, the use of 90° bends should be minimized. One 90˚ bend causes as great a loss in suction power as one meter of hose or pipe. Always shorten hoses and pipes so that the installation is as short as possible. The longer the installation, the greater the pressure loss = less suction power. Always use the largest possible hose diameter. If your hood or motor was born with Ø160 mm, you must use at least Ø160 mm hose, etc. If you just go down one size, it can reduce the effect by up to 66%.




If the standard duct is to be longer, then an extra long duct or an extension adapter must be used.
In those cases there will be an additional price.






In some houses, the ceiling has a slope.
