Bathroom Extractor Fans

Bathroom extractor fans – Quiet and efficient ventilation for every bathroom

Why choose the right bathroom extractor fan?

A bathroom extractor fan is a key element of every modern home, as it effectively removes moisture, prevents the appearance of mould and ensures fresh air in the room. In the bathroom, trapped moisture is the most common cause of furniture damage, peeling paint on the walls and the formation of unpleasant odours. With a properly chosen bathroom fan you ensure a healthy and pleasant environment, extend the service life of your bathroom fittings and at the same time significantly improve the air quality in the room.

Types of bathroom extractor fans – From axial to centrifugal, for every need

Axial and inline duct fans for the bathroom

Axial fans are the most common choice for short ventilation runs. They are used to extract air directly from the bathroom through a wall or a short duct, ideal for smaller rooms and shorter ducts. Inline duct fans Ø100 or inline duct fans Ø125 are often used for the direct extraction of moisture.

Centrifugal and radial fans for the bathroom – Power and efficiency for longer ducts

When you need more power and higher pressure (more pascals), centrifugal fans are the right choice. They are designed for long-lasting and efficient ventilation where ducts are longer, flow rates are higher and pressure losses are significant. As such, centrifugal bathroom fans are best for larger rooms and professional applications.

Quiet bathroom extractor fans – For comfort without noise

Quiet bathroom fans are designed to run virtually silently, with a typical noise level below 25–30 dB(A) – that is quieter than a whisper or a refrigerator (around 30 dB), and considerably less than a normal conversation (60 dB). Choose them when you want maximum peace in a room, e.g. in bedrooms or larger apartments.

Advanced functions – Sensors, timers and smart controllers

Bathroom extractor fan with humidity sensor – Automatic protection against condensation

Fans with a humidity sensor are extremely popular, as they switch on automatically when they detect increased humidity (e.g. after showering) and switch off again once the air is dry. This ensures fully automatic operation, energy savings and constant protection against mould.

Light sensor and timer – More comfort and automation

Advanced models also include a light sensor that switches the fan on when you enter the room or when the light changes, as well as a timer that sets the switch-off time after use. By using the MR and MRH controllers, you can easily adjust the sensor sensitivity and the operating time to suit your needs.

Connecting and installing bathroom extractor fans

Connection with other ventilation elements

A bathroom extractor fan can be connected to existing ventilation systems or used as a standalone unit. A combination with ventilation valves, wall vents or ducts is possible.

Ceiling or wall mounting – Flexibility for every room

Most fans allow both wall and ceiling mounting. Ceiling bathroom extractor fans are excellent for small rooms or where wall installation is not possible.

Instructions for quick and safe installation of a bathroom fan

• Prepare an opening of the appropriate diameter.

• Use the supplied brackets and fixing material.

• Connect the power supply and check operation.

• For larger duct systems, choose a more powerful, centrifugal model.

Technical comparisons and common buyer dilemmas

Air flow rates and power comparison

• Air flow (e.g. 90–110 m³/h) is the key figure for the size of the bathroom.

• For a standard bathroom (e.g. 2x3 m) an inline duct fan Ø100 with a flow of 80–100 m³/h is usually sufficient.

• For larger or more remote rooms, use an inline duct fan Ø150 or a centrifugal bathroom fan with more pressure.

Sleeve bearings or ball bearings – The difference in durability and quietness

• Ball bearings: Longer service life (up to 40,000 hours), quieter operation, more suitable for frequent use.

• Sleeve bearings: An economical solution for occasional use, suitable for holiday homes or auxiliary rooms.

Moisture resistance and IP protection

• Choose a fan with an IP rating (e.g. IP35 or higher), which means safety even in the most humid rooms.

• Backdraught shutters prevent the return of cold air and odours.

Quietness comparison: How quiet is a "quiet" bathroom extractor fan?

• Quiet models: 20–30 dB(A) (whisper: 20 dB, refrigerator: 32 dB, normal conversation: 60 dB).

• Standard models: 30–45 dB(A).

• If you are more sensitive to noise, we recommend a quiet bathroom fan.

The most common uses of bathroom extractor fans

• Daily use – preventing mirror fogging and wall damage.

• Ventilation of utility or WC rooms – quick removal of odours.

• Help with drying laundry in indoor spaces.

• Ventilation in the kitchen or cellar – special inline duct fans.

Technical data of bathroom fans

Frequently asked questions (FAQ)

How does a bathroom extractor fan with a humidity sensor work?

A fan with a humidity sensor switches on when it detects higher humidity in the room (e.g. after showering) and switches off automatically when the humidity level drops. This ensures fully automatic ventilation.

How quiet are bathroom extractor fans?

Quiet bathroom extractor fans operate at 23–27 dB(A), which is quieter than most household appliances. For comparison, a refrigerator is around 30 dB(A), while a normal conversation is 60 dB(A).

Can I mount a bathroom fan on the ceiling?

Yes, some models allow ceiling or wall mounting. Ceiling bathroom fans are ideal for rooms without the option of wall installation.

What is the difference between an axial and a centrifugal fan?

Axial fans are suitable for short ducts and direct ventilation, while centrifugal fans are suitable for longer duct systems where greater pressure (more pascals) is required.

Do fans with additional functions consume more energy?

No, advanced fans with MR/MRH controllers are more energy efficient, as they only operate when needed.

A bathroom extractor fan is an indispensable part of every home, ensuring an optimal climate and preventing mould, moisture and unpleasant odours. Choose a quiet bathroom fan, a model with a humidity sensor or a powerful centrifugal fan for more demanding rooms.
