Used in the scope of an ALIZÉ III humidity controlled ventilation system, (Technical Appraisal 14/13-1910), ISOLA  HY air inlets are used in conjunction with the system’s humidity controlled or timed extraction vents.
They are characterized by a flowrate varying from 6–45 m³/hour (at 20 Pa pressure head) in line with the room’s humidity variations.
The ISOLA HY or ISOLA HY RA humidity controlled acoustic air inlet installed on the inside, is made from white polystyrene. For installation in main rooms (living and bedroom) to supply

air renewal in humidity controlled, single flowrate forced ventilation systems.

It works both on vertical walls and on inclined planes (e.g., roof skylights, undersides of roller shutter boxes). The cowl for fittting to the external wall 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 indoor side, the base of the air inlet (ISOLA HY) or the muffler extension (ISOLA HY RA) is held in place by 3 screws. The cap is a push-fit. The cap can also be screwed on for a more secure hold.

For fitting to curved joinery, insert the round-fit base between the air inlet and the joinery.


The cowl on the external wall is centred on the slot and held in place by 3 screws (horizontal fitting).

The components must be kept easily accessible for cleaning and maintenance.
