Closable grills

Combinations of outside wall grills with adjustable louver blades have a twofold function in the intake and exhaust openings of air-conditioning plants. Firstly, they provide good protection against the penetration of rain, leaves and birds. Secondly, this combination allows the air volume to be regulated or the opening to be closed during periods of shutdown.
