Aluminium grilles

Back to Diffusion

The GL Series units are aspiration grilles with fixed horizontal blades 45° degree inclined. They are used for external air-intake, for ambient exhausted air-expulsion, for air-recycling into internal structures and for general ventilation. It is recommended the application of a protective bird net for the external installation of these grilles.
