ALG LINEAR VENTILATION GRILLES Characteristics: Rectangular aluminium air supply or exhaust ventilation grilles, with a single row of fixed vanes, optionally with a second row of movable vanes, standalone or linear installation. The ALG ventilation grilles are designed for low and medium pressure ventilation systems. They may be mounted both in walls and ceilings. The frame and fixed vanes are made of aluminium anodised to natural colour or painted with RAL9010 white paint. On request, other RAL colour lacquering is available. In case of a linear version the grilles consist of sections of equal length connected with each other by means of bayonet connectors. The maximum length of a single element is 2 meters. Figure 3.
