They are associated with the humidity sensitive or timed extract units of the system.
With a pressure difference of 20 Pa, they provide a variable airflow of 5 to 45 m³/h depending on the humidity level in the room.

Installed on the inside and made of polystyrene, the humidity sensitive ISOLA HY or ISOLA HY RA air inlet is installed in the main rooms (living rooms and bedrooms) to supply fresh air from humidity sensitive single flow mechanical ventilation systems. It works on vertical walls as well as on inclined surfaces such as roof windows, under roller shutter boxes, etc.
The facade cap, fitted on the outside, is made of UV and weather-resistant polystyrene in the same colours as the air inlets.

• On the inside, the air inlet base (ISOLA HY) or the acoustic extension (ISOLA HY RA) is fixed with 3 screws. The cover is fitted by simply fitting it into place.
• For mounting on curved joinery, use the curved base placed between the air inlet and the joinery.
• On the outside, the cap, centred on the notch, is fixed with 3 screws.
