9 RSO Transfer air grille Adjustable according to wall or door thickness Very small pressure loss Prevents visual contact between rooms Grille for transfer air between rooms. Installed in door or wall. Installation thickness for grille and frame is -0 mm. If wall or door thickness exceeds 0 mm, two grilles can be used without mounting frame. Airflow through the grille is caused by pressure difference between rooms. Structure and dimensions Manufactured of aluminum profiles. Bars are V-shaped. Measures to fit cutting measures in wall or door (AxB). Standard colour white (RAL 0). Other RAL colours available.
