Exhaust air system

Exhaust fans are very suitable for functional rooms such as the bathroom, kitchen or even the utility room. They transport the exhaust air either directly into the open air or via exhaust air shafts. At LUNOS, they are available with or without heat recovery. Click here or our extractors with or without heat recovery.

The Benefits of exhaust air systems

  1. Improved air quality: Exhaust air systems provide efficient exchange of stale air, removing odors, moisture and pollutants, contributing to overall improved indoor air quality.
  2. Protection against mold growth: By specifically removing humid air in rooms such as bathrooms and kitchens, exhaust air systems minimize the risk of mould growth as they reduce the basis for mould growth, namely moisture.
  3. Energy efficiency: Efficient exhaust air systems can reduce the need for heating or cooling energy by controlling the air exchange in a targeted manner. This leads to energy savings and more sustainable operation.
  4. Comfortable indoor climate: Exhaust air systems help to create a comfortable indoor climate by removing excess heat, moisture and odors. This leads to a comfortable and healthy living environment.
  5. Individual room control: Decentralized exhaust fans allow targeted ventilation of individual rooms. This offers flexibility and allows ventilation to be adjusted as required, which is particularly beneficial in rooms used for different purposes.

1. Why is an exhaust air system important in rooms such as bathrooms and kitchens?

Exhaust air systems are important to efficiently remove unpleasant odors, moisture and pollutants, which improves the air quality in living spaces.

2. What is the difference between exhaust fans and other ventilation systems?

Unlike other ventilation systems that circulate the air, exhaust fans transport the stale air directly outside, which is particularly important in rooms with increased humidity or odors.

3. What types of exhaust air systems are there?

There are central exhaust air systems that serve several rooms and decentralized exhaust air fans that are suitable for individual rooms or local applications such as bathrooms and kitchens.

4. Are exhaust air ducts necessary and how do they work?

Exhaust air ducts are necessary if the exhaust air cannot be routed directly to the outside. They guide the exhaust air safely to the outside, but at the same time ensure controlled air exchange.

5. How quiet are exhaust air fans?

The volume of exhaust air fans varies, but modern models are generally quiet. Manufacturer information on the decibel rating helps to identify quieter models.

6. Can an exhaust air system save energy?

Yes, efficient extract air systems can save energy by selectively exchanging the air in a room, reducing the need for heating or cooling energy.

7. How is an extract air system maintained?

Maintenance includes regular cleaning of fans and filters, checking exhaust air ducts for blockages and servicing motors and control units.

8. What factors influence the selection of the right exhaust air system for my home?

Room size, air exchange requirements, location and personal preferences all influence the choice. It is advisable to seek professional advice.

9. Are smart exhaust air systems available and what advantages do they offer?

Yes, smart extract air systems often offer remote operation, programmable schedules and integration with smart home platforms, making it easier to customize and control ventilation.
