ᐅ Looking for a bathroom exhaust fan with humidity sensor, ducted exhaust only

Hello Everyone,

For the wet rooms (bathroom, guest toilet, and utility room) in the new build of a single-family house, only exhaust ventilation systems are required due to the conditions for "KfW 55EE". I have already had the wall openings for DN 100 installed as well as the power cables for connecting the fan (constant power).

I am now looking for an exhaust fan with the following features:
- pure exhaust air
- DN 100
- humidity sensor
- runs on constant power (no switch connection available)
- backdraft damper
- adjustable settings for run-on time and humidity level at which it turns on or off

I have already searched extensively on Amazon and read reviews and specifications. So far, I have only found one suitable option: the Lospitch bathroom fan.

Maico offers the "maico eca 100 ipro kh," but it says the settings can only be adjusted using a switch.

Do you have any additional recommendations for a bathroom fan that meets my requirements?

Greetings from Southern Hesse

Maybe this matches your requirements

Where does the fresh air enter the house that the fan extracts?

This model was also considered by us, but it will probably be a Lunos Silvento now. There are different circuit boards available that allow for control systems to be implemented. Maybe that could work for you.

The rest of the ventilation concept should definitely be considered here, but sorry, I can’t resist this one:

Since this probably applies here:

• n50 = 1.5 1/h (with mechanical ventilation systems)

simply through leaks in the building envelope 😉

Thanks in advance for the quick replies!

Currently, only through the window reveal vents, so not very effective.

Sorry, I didn’t fully understand your post. We don’t have a mechanical ventilation system in the house. At our request, the energy consultant did a calculation without a ventilation system. As compensation, window reveal vents and these three exhaust devices were specified, among other things. Nothing more.
