Wall ventilation

Why choose Wilms wall ventilation?

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.

Better indoor climate, lower energy costs

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.

Benefits of Wilms wall ventilation:

• Decentralised Type D ventilation system with mechanical supply and exhaust
• Heat recovery up to 75%: save energy and money
• No air ducts or ventilation grilles required
• Easy to install in any type of wall
• Whisper-quiet and low-maintenance
• Modern design: available in all RAL colours

Energy-efficient thanks to heat recovery

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.

HRV benefits:

• Warm in winter, cool in summer (night cooling)
• No draughts thanks to smart airflow (Coanda effect)
• Lower heating costs and greater comfort

Modern design that suits any home

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).

Balanced ventilation with easy maintenance

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.
