Barely visible
A slim vertical slot pattern beside the window is all you see. The window’s clean outline remains intact and the room feels calm.
Keep warmth inside
Heat recovery transfers some warmth from outgoing air to fresh incoming air. Fresh air enters while unnecessary winter heat losses are reduced.
Ventilation to suit your day
We demonstrate settings, controls and sound levels on the actual installation, helping you find the setting that suits your routine.
Straightforward maintenance
Filters are cleaned or replaced according to the manufacturer’s instructions. Ventilation exchanges air; it does not provide active cooling. That requires a separate system.
Your viewing checklist
- Ask for the exact model and operating principle.
- See normal operation and higher settings demonstrated.
- Check access once furniture is in place.
- Document maintenance, filters and running costs.
