Exhaust air system
Why is an exhaust air system essential in areas such as the bathroom and kitchen?

An exhaust air system plays an essential role in removing odors, moisture and pollutants, resulting in a noticeable improvement in indoor air quality.

How does an exhaust air fan differ from other ventilation systems?

Unlike conventional ventilation systems, which merely circulate the air in the room, exhaust fans transport the stale air directly outside. This is particularly relevant in rooms with high levels of humidity or odors.

What different types of exhaust air systems are there?

A distinction is made between central exhaust air systems, which serve several rooms simultaneously, and decentralized fans, which are designed for individual rooms such as bathrooms or kitchens.

When are exhaust air ducts necessary and how do they work?

Exhaust air ducts are used when direct air ducting to the outside is not possible. They direct the exhaust air to the outside and support controlled air exchange.

How loud are exhaust fans?

The volume of exhaust air fans can vary. However, modern appliances usually work very quietly. The manufacturer's decibel specifications help to identify particularly quiet models.

Can exhaust air systems save energy?

Yes, efficient exhaust air systems help to save energy by providing fresh air in a targeted manner and thus reducing the need for heating or cooling energy.

How is an exhaust air system maintained?

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

What factors play a role in the selection of a suitable exhaust air system?

The size of the room, the necessary air exchange, the structural conditions and personal preferences are important selection criteria. Professional advice is recommended.

Are there intelligent exhaust air systems and what advantages do they offer?

Yes, smart extract air systems often allow remote control, programmable settings and integration into smart home systems, which makes it easier to control and adjust the ventilation.

Heat recovery system
How efficient are ventilation systems with heat recovery?

The efficiency of ventilation systems with heat recovery depends on several factors, including the type of heat exchanger, the insulation of the building and the way it is used. In general, these systems contribute significantly to energy savings by using the heat from the exhaust air to preheat the fresh air.

Do ventilation systems with heat recovery require intensive maintenance?

The amount of maintenance required can vary depending on the system. In most cases, filters, heat exchangers and other components need to be checked regularly. Professional maintenance in accordance with the manufacturer's instructions ensures that the system works optimally.

Can ventilation systems with heat recovery reduce moisture problems?

Yes, these systems support humidity control through targeted ventilation and dehumidification. In this way, they help to prevent condensation and mold growth.

Are ventilation systems with heat recovery only suitable for new buildings?

No, ventilation systems with heat recovery can also be installed in existing buildings, provided the building structure and technical requirements allow this. Careful planning and expert advice are essential here.

How loud are ventilation systems with heat recovery?

Modern systems are usually designed to be quiet, although the volume varies depending on the model. The sound power level provides an exact indication of the noise development of the respective model.

Can a ventilation system with heat recovery improve indoor air quality?

Yes, such systems improve indoor air quality by continuously supplying fresh air and filtering out pollutants such as dust, pollen and other contaminants.

Does the outside temperature influence the efficiency of heat recovery?

Yes, at very low outside temperatures, efficiency can be affected as the fresh air may have to be additionally heated, which can reduce the heat exchange rate. Nevertheless, ventilation systems with heat recovery remain more efficient than simple ventilation systems, even in cold weather.

Hybrid system
How does heat recovery work in a hybrid ventilation system?

With heat recovery, the heat from the exhaust air is used to preheat the incoming fresh air. This increases energy efficiency and contributes to a pleasant indoor climate.

For which rooms are hybrid ventilation systems particularly suitable?

Hybrid ventilation systems are ideal for living spaces, offices and other areas that require demand-based ventilation and need to be operated in an energy-efficient manner at the same time.

How is a hybrid ventilation system controlled?

They are usually controlled automatically by sensors that monitor parameters such as air quality and humidity. However, it is also possible to adjust the settings manually.

Are hybrid ventilation systems suitable for new and existing buildings?

Yes, hybrid systems can be used in both new and existing buildings, as they can be flexibly adapted to different architectural and usage-specific requirements.

What is the importance of air quality in hybrid ventilation systems?

Air quality is of central importance. Sensors detect pollutants and CO₂ levels and adjust the ventilation to ensure healthy and pleasant indoor air.

Can hybrid systems also contribute to cooling the rooms?

Yes, many hybrid systems enable cooling in summer by using cool outside air, which can reduce the use of air conditioning systems.

What kind of maintenance does a hybrid ventilation system require?

Maintenance includes regular cleaning of the filters and checking the sensors. Some systems automatically inform you when maintenance is required.

What financial benefits do hybrid ventilation systems offer in the long term?

Thanks to high energy efficiency and reduced operating costs, hybrid systems save costs in the long term and increase the value of the property thanks to their modern and sustainable design.

Sound insulation
Why is sound insulation essential for ventilation systems?

Soundproof fans help to shield sources of noise such as traffic noise and at the same time ensure sufficient air circulation in the building, creating more pleasant room acoustics.

To what extent does the construction method influence the sound insulation of ventilation systems?

The construction method has a major influence on sound insulation performance. Our ventilation products are designed to provide effective noise reduction in both new and older buildings.

Can I adjust the sound insulation of my ventilation system myself?

With our design tool, the standard sound levels can be calculated depending on the system configuration and the structural conditions in order to optimally adapt the sound insulation performance of the ventilation.

Which products offer the best sound insulation for my home?

Models such as the e²60 and LUNOtherm S+ are characterized by particularly high sound insulation values and are ideal for rooms that place high demands on quiet and comfort.

What advantages do soundproof ventilators offer over conventional ventilation systems?

LUNOS soundproof ventilators not only reduce external noise, but also minimize the operating noise of the ventilation system, which contributes to a quieter living and working atmosphere overall.
