APPLICATIONS: The fans of this series are suitable for sucking clean or slightly dusty air and they are mainly used in air-conditioning plants, in spray booths, for grain and feed drying, in cooling plants and in general when it is requested to convoy air with low pressure. The particular shape of the impeller with reversed blades assures a high efficiency. In the standard execution, the temperature of the sucked fluid must not exceed 80°C. TECHNICAL FEATURES: Scroll made in beaded and welded sheet steel, impeller with reversed blades made in welded sheet steel dynamically balanced, motor support (when present) made in welded sheet steel and steel sections. OPERATING RANGE: Pt = 10 - 390 mm. H2O - Q = 1.320 - 96.000 mc/h EXECUTIONS: The fans of this series are equipped with three-phase asynchronous electric motors according to UNEL-MEC standards coupled directly or by transmission to the impeller. They can be built with clockwise (RD) or anticlockwise (LG) rotation and they can be oriented from 45° to 45°. On request single-phase electric motors till size 90 can be supplied. SPECIAL EXECUTIONS: For all the fans of this range special executions may be possible, like the construction in stainless steel or for high temperatures and the ATEX execution for the zones 1-21 or 2-22.
