Black Edition
Get the basement of your dreams
Live your dreams in a basement with a healthy indoor climate
Utilise your basement square metres
A healthy indoor climate in the basement is essential if you want to utilise the full potential of your home. Many basements sit unused or only serve as storage rooms because humidity, cold and poor ventilation make them uncomfortable to spend time in. But with the right indoor climate, basement square metres can be transformed from wasted space to valuable square metres.
When moisture and bad air are removed and ventilation is optimised, you create an environment that is both healthy and comfortable. This means fewer mould problems, better air quality and an overall healthier home to live in.
At the same time, the value of the property increases significantly when the basement becomes an area you can actually use. A healthy indoor climate opens the door to new possibilities: extra living space, home office, hobby room, fitness centre, guest room or simply dry, comfortable storage space. The square metres take on a whole new function and buyers see great potential in a basement that is dry, ventilated and in good condition.
A good indoor climate in the basement is an investment that improves the health of your home, provides more usable space and creates economic value.

DUKA One
Create a healthy indoor climate in the basement - easily, efficiently and without major renovations
Ensuring a healthy indoor climate in the basement can quickly seem like an extensive and unmanageable project. Moisture, bad air and a stagnant indoor climate make the basement a place to avoid. But with DUKA One, With an efficient one-room ventilation solution, it becomes much easier to create a comfortable and healthy basement environment.
The DUKA One is mounted directly in the outer wall and requires minimal installation. The unit automatically switches every 70 seconds between sucking out stale, moist air and blowing in fresh, filtered outdoor air. This continuous air exchange gives the basement the breath of fresh air it often lacks - creating an indoor climate that is both healthier and more stable.
When air is constantly in motion, it is much harder for moisture to stick to walls, floors, furniture and stored items. This significantly reduces the risk of moisture damage, mould and mildew. At the same time, you avoid the typical “basement odour” that often settles in clothes, furniture, cardboard boxes and other stored items. With fresh air, the basement becomes a usable and comfortable space again.
A healthy basement indoor climate allows you to utilise the full potential of your home. Once the humidity is under control, the basement square metres can suddenly be used for hobby rooms, storage without worries or as extra living space - and the value of the home increases accordingly.
With DUKA One you get a simple, energy-friendly and efficient solution that gives your basement new life. An investment that both improves the health of your home and increases the possibilities of using the basement actively in everyday life.
Black Edition
When it doesn't always have to be white
Many choose white as the standard colour for ventilation solutions, but with Black Edition you get the benefits of advanced ventilation and Aesthetic minimalism. The black colour makes the unit more neutral - especially in modern, dark or stylish interiors - and prevents the fan from dominating the room. The Black Edition fits perfectly in rooms with dark walls, woodwork, concrete, concrete ceiling or industrial design, but works equally well in classic homes where discretion is a plus.
At the same time, you get all the functionality of the DUKA One: heat recovery, energy-efficient operation, low noise level, easy installation and flexible supply air settings. A black ventilation screen makes it more attractive to place the unit in living rooms, bedrooms or basements - yes, even in basements where you want a more “finished” and residential feel.
