Valves for aluminium windows

***® in connection with blind mechanism

The ***® valve is perfectly suited for use in connection with a #blind mechanism#.
In this case, no separate outer grille is needed as the valve takes in air through the blind mechanism.
As the valve can be removed from the installation foot without any tools for replacing the filter, it is also easy to use by end consumers.
