AIRA HY air inlets are for use in an ALIZÉ III humidity controlled ventilation system (Technical Appraisal 14.5/17-2269 and 14.5/17-2268) where they work in conjunction with the system’s humidity controlled or timed extraction vents. They are characterized by a flow that varies from 5–45m³/h according to the humidity in the room, at a pressure head of 20Pa. 
The humidity controlled AIRA HY air inlet for indoor fitting is made from polystyrene. It is installed in main (living and bed) rooms to supply the air renewal in single-flowrate, humidity controlled forced ventilation systems.

It works both on vertical walls and on inclined planes (e.g., roof skylights, undersides of roller shutter boxes). The external wall cowl is made from UV- and weather-resistant polystyrene in the same colours as the air inlets.
Exclusively for fitting to surfaces sheltered from bad weather. For non-sheltered surfaces please enquire with us.

On the inside, the air inlet is centred on the 354 x 12mm slot and fastened by 3 screws. It has a clip-on cap. On the outside, the cowl is centred on the slot and fastened by 3 screws (horizontal fitting).
The components must be kept easily accessible for maintenance.
