The ISOLA 2 or ISOLA 2 RA acoustic self-regulating air inlet for indoor fitting is made from white polystyrene. The insect screen function of the grille is directly provided by the inlet airflow. For installation in main rooms (living and bedroom) to supply air renewal in single flowrate forced ventilation systems.

Available in flowrates of 22, 30, or 45m³/h.

It works both on vertical walls and on inclined planes (e.g., roof skylights, undersides of roller shutter boxes).

The cowl for fitting 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 inside, the base of the air inlet (ISOLA 2) or the muffler extension (ISOLA 2 RA) is held in place by 3 screws. The cap is a push-fit.

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

On the outside, the cowl 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.
