Loading…Ventilation
Ventilation is important for a healthy and comfortable indoor climate. A good ventilation system provides air exchange, moisture removal, reduction of polluted indoor air and a better balance between comfort and air quality.
At Hewa, you will find ventilation solutions for homes, offices, workshops, technical rooms and project-based installations. When selecting the right solution, check airflow, room function, duct route, air extraction, air supply, sound level, mounting position, maintenance and the technical layout of the ventilation system.

Ventilation for air exchange and a healthy indoor climate
Ventilation provides continuous air exchange, moisture removal and improved air quality in homes, offices, workshops and technical rooms. A correctly selected ventilation system helps reduce polluted indoor air, condensation and stuffiness.
Selecting ventilation
The right ventilation solution depends on room function, required airflow, duct route length, air extraction and air supply position and the building situation. Wet rooms, technical rooms, workshops and occupied spaces often have different requirements for extraction, sound level and capacity.
Within the broader climate range, also review air conditioning and ventilation for indoor climate, air conditioning installation material and air exhaust material for ventilation ducts.
Important when choosing ventilation
- Match airflow to room function, room volume and usage intensity
- Check duct diameter, duct length, bends and pressure loss
- Check sound level, mounting position, vibration damping and service space
- Select the right combination of ventilation duct, grille, fitting and roof terminal
- Allow for air supply, air extraction and air balance between rooms
- Check that condensation, moisture load and backflow are properly prevented
- Have design, installation and electrical connection carried out by a qualified installer
Applications within ventilation
Homes and apartments
For air exchange in kitchens, bathrooms, toilets, storage rooms, laundry rooms, bedrooms and other living areas where fresh air and moisture removal are important.
Offices and workspaces
For rooms where several people are present and air quality, comfort, sound level and reliable extraction are important for the indoor climate.
Technical rooms
For installation, storage and technical rooms where heat, moisture or polluted air must be removed in a controlled way.
Duct route, airflow and installation correctly matched
A ventilation system only works properly when fan, duct diameter, grille, roof terminal and fittings are technically matched. Too many bends, undersized ducts or long duct routes can increase pressure loss, reducing air exchange and increasing sound levels.
For installers, the complete air path is especially important. This includes free air supply, correct air extraction, suitable ventilation ducts, non-return provision, roof terminal, fire-safe and service-friendly installation and component accessibility. A carefully designed ventilation system helps prevent moisture issues, noise problems, insufficient extraction and unnecessary service complaints.
Frequently asked questions about ventilation
What is ventilation used for?
Ventilation is used to remove polluted or moist indoor air and supply fresh air. This supports air quality, moisture control and comfort in the room.
Which ventilation solution do I need?
The right solution depends on the room, required airflow, duct route, extraction position, sound level and building situation. This should preferably be assessed technically.
What is important with ventilation ducts?
Check duct diameter, length, bends, airtightness, insulation, pressure loss, cleanability and the correct combination with grilles, fittings and roof terminals.
How can ventilation noise be reduced?
Noise can be reduced through correct sizing, sufficient duct diameter, fewer sharp bends, low-vibration installation, suitable grilles and a fan that is not unnecessarily overloaded.
What should an installer check during installation?
Check airflow, duct route, fixing method, roof or wall terminal, condensation, non-return provision, electrical connection, service space and the technical documentation of all components.
