Weather protection grille
Weather protection grilles as a component of air conditioning plants prevent rainwater from entering the intake or exhaust openings of building facades, or they help with the natural ventilation of building complexes. The weather protection grille consists of specially shaped, rainwater-repellent, horizontally arranged lamellas, which are attached to a circumferential frame.
The lamella distance is a good compromise between the protection effect and pressure loss. Weather protection grilles are provided with a bird protection grille on the backside.
The standard design of all weather protection grilles has a non-perforated frame. The design that has a perforated frame must be called for accordingly, if needed. Note: As the weather protection grilles cannot ensure absolute protection against entering moisture, a drainage system must be provided in the subsequent duct section, depending on the demand.
