By adjusting the angle of discharge can be achieved long-range during the winter months (70°÷90° tilt recommended in heating mode) or smooth stratification of cool air during the summer months (30°÷45° tilt recommended in cooling mode). The “Heating/Cooling” modes can be adjusted mechanically (manually) or automatically (via an electric actuator). The automatic adjustment of the blades can be performed on up to 12 diffusers simultaneously. This allows quickly and without additional costs changing of the mode for the whole site. Constructed of steel metal sheets with powder coating. The air flow rate of a single ventilation grille can be 600m3/h up to 3500m3/h (166l/s – 972l/s).
