VM 15 + CAVM


Slot (in mm) 250 x 15



The VM self-regulating air inlet for indoor fitting is made from white polystyrene. It can be fitted with a GAM insect screen or a CG-VM grille cover. Designed for installation in main rooms (living and bedroom) to supply air renewal to single flowrate forced ventilation systems.

Available in flowrates of 15, 22, 30, or 45m³/h. The 15m³/h air inlet provides additional flowrates of 22 or 30m³/h and the 22m³/h allows up to 30m³/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 extrnal wall is made from UV- and weather-resistant polystyrene in the same colours as the air inlets (except the GAVM aluminium external wall grille).
Exclusively for fitting to surfaces sheltered from bad weather. For non-sheltered surfaces please enquire with us.

On the inside, the air inlet base is centred on the 250 x 15mm slot and fastened by two screws.

On the outside, the external wall cowl or grille is centred on the slot and fastened by 2 screws (horizontal fitting).

The GAM insect screen must not be used if the VM is fitted with the CG-VM cap.

The components must be kept easily accessible for maintenance.

VM 15/22/30 m³/h air inlets: the inlet airflow rate is determined by the snap-off tabs (marked 15, 22, and 30) on the two regulator bar holding clips. The lowest remaining value indicates the flowrate.

The 15m³/h model can also be modified in-situ to provide flowrates of 22 or 30m³/h by carefully breaking off the relevant snap-off tabs. Break the 2 tabs marked 15 to obtain 22m³/h and the 2 tabs marked 22 to obtain 30m³/h.

The 22m³/h model can also be modified in-situ to provide a flowrate of 30m³/h by carefully breaking off the relevant snap-off tabs. Break the 2 tabs marked 22 to obtain 30m³/h.
