Supply valve automatic mini air intake valve automatically.

Supply valve automatic mini air intake valve automatically.

MINI air - supply device is designed for use inside buildings, and is intended to provide fresh air into the room using specific mechanical ventilation. Reduced size - it is space - saving installation in the case of MINI installation in hallways or walls. The rate of air into the installation hole should be about 3 m / s. Higher speeds could cause additional noise and larger pressure.

When using the reduced inlet and speeds the recommended installation hole sizes, i. e. , 0.2 x 0.5 m, corresponding to the recommended selection of possible fan performance operating with supply installation. These performance should vary from 1100 to 1800 m / h.

The desired pressure differential at which the valve opens fully, and can be adjusted from 25 to 40 Pa (the difference between ambient air pressure and the pressure in the room).

Ventilation device is also equipped with retractable front panel through which it can be closed, for example, in winter
