Fresh indoor air isn’t a luxury, it’s essential for a healthy and comfortable indoor climate. Yet traditional ventilation systems often come with major drawbacks: disruptive demolition work or complex air ducting. With Wilms wall ventilation featuring Airria® technology, you choose a smart, aesthetic, and energy-efficient solution. This Type D ventilation system ensures mechanical supply and exhaust of air without unnecessary heat loss.
Wilms wall ventilation can easily be installed in any type of wall and works fully decentralised, room by room. Unlike a central ventilation system, you decide where and when you ventilate — without complicated ductwork, without losing space, and without having to replace your windows.
This helps protect your home against moisture and mould issues, while reducing heating costs and CO₂ emissions at the same time.
With Wilms, you combine ventilation with heat recovery (HRV). Thanks to the integrated heat exchanger, the system recovers up to 75% of the heat from the extracted air. In summer, you can also enjoy night cooling without heat transfer, perfect for fresh nights without air conditioning.
The ventilation unit is discreetly integrated into a stylish aluminium housing with standard dimensions of 1000 mm (W) x 316 mm (H) x 220 mm (D).
Each ventilation unit contains a set of smart filters that keep dust, pollen, and pollutants out of the air. A notification on the unit automatically indicates when the filters need to be replaced. Replacing them is quick and easy: with one click you install a new filter and keep your indoor air healthy and clean.
Choose a smart ventilation system that fits your home. A decentralised Type D ventilation system for healthy air in every room.
