Bathroom exhaust fans

Why is a bathroom extractor fan needed?

In the spaces between tiles (fugue), removing mold without leaving pigment stains is very difficult, sometimes impossible. Also, in addition to the moisture that occurs after washing, towels, clothes, and a washing machine are usually dried in this room.

Therefore, it is necessary to take timely measures and be sure to ensure the removal of excess moisture from the bathroom, also a drier environment contributes to greater comfort, so in order to ensure a positive microclimate in this room, an exhaust fan for the bathroom is essential. New generation bathroom fans extract not only moisture, but also air with less oxygen, unpleasant odors.

What should a bathroom fan be like?

When choosing a bathroom fan, you need to consider its power and efficiency, noise level, and functionality. The most popular and useful functionality is bathroom fans with humidity sensorThis means that you can leave the fan on after taking a bath and it will automatically turn itself off as soon as it senses that the high humidity in the air is no longer present (note that a bathroom fan with a timer or humidity sensor is always connected with a three-core cable).

Also, bathroom exhaust fan with check valve ensures that air flow is prevented from being drawn back into the room, or heat loss when the fan is operating, in addition to all this, it also prevents insects from entering the room, but you need to assess whether such a valve is necessary. This can be done by placing a sheet of paper against the ventilation opening - if it leans towards the inside of the room, then the valve is needed, if it is pulled into the ventilation opening - then it is not.

How to choose an exhaust fan?

You should estimate the volume of the bathroom to know how many cubic meters of air the bathroom fan should extract. The volume number should be multiplied by 10 and you will get the most suitable fan performance. The average bathroom is 5m2 and the standard height is 2.5m, so to ensure comfortable air circulation in this type of bathroom, the air flow should be at least 125m3/hour.

It is also good to know the length of the duct leading to the outside or ventilation shaft. If the length of the horizontal duct exceeds 1.5m, then pressure losses will occur, which will significantly reduce the fan's performance, so in this case, a centrifugal fan should be chosen.

Another important aspect is the diameter of the ventilation duct, usually the standard is 125 mm or 100 mm, but there may be other diameters, so you should measure before ordering to order the right option.

What bathroom exhaust fans can we offer?

The household exhaust fans offered in our e-shop are axial and centrifugal. Centrifugal ("BLAUBERG VALEO") are designed for ventilation systems with higher resistance and are particularly suitable for those with long horizontal and vertical ducts or ventilation openings (e.g. old apartment buildings). This type of fan motor is able to independently regulate pressure differences to ensure the most efficient air circulation.

Renson wave axial fans with EC motors are extremely economical and highly efficient. They have integrated humidity, C02, and odor sensors, and are controlled and easily programmed via a mobile application. We can leave such fans on constantly, because they monitor air parameters and independently select the most efficient level.

Quiet bathroom fan also a nice and for some necessary feature of the device, so we can offer Blauberg Sileo series fans for the bathroom and beyond, they have an exceptionally high insulation class and are among the quietest on the market due to additionally installed anti-vibration gaskets.
