CAIRE® flex
Passive ventilation – Compact and inconspicuous
The CAIRE® flex passive ventilation system is based on pressure equalisation between indoor and outdoor air and can be compactly and inconspicuously mounted in the window rebate. It ensures permanent basic ventilation, prevents mould and works independently.
Passive window rebate ventilator
Application range
CAIRE® flex is a window rebate ventilator for existing and new buildings. The system allows for a permanent exchange of air when the window is closed and is especially useful for preventing mould by removing moist air to the outside. The passive ventilator does not need to be controlled, and is therefore resistant to faults and requires little maintenance. CAIRE® flex is easy to install and fits almost invisibly into various window systems. The air flow rate can be increased by installing several window rebate ventilators.
Indoor inflow
CAIRE® flex allows fresh air to flow into the window rebate through targeted openings and out into the room through the upper window area on the inside: perfect for comfortable basic ventilation that transports moisture outside and effectively prevents mould. Depending on the air pressure difference, the system achieves an air flow of 2 to 13 m³ per hour. In strong winds, CAIRE® flex closes by itself and prevents draughts.
Layout and function
CAIRE® flex is almost invisible. The ventilator is concealed in the window rebate, is easy to install and retrofit. Even with the smallest pressure differences, it reliably brings fresh air into the house without you having to open the window. So mould doesn’t stand a chance.
