In the standard execution, the temperature of the sucked fluid must not exceed 80°C.
- Scroll made in beaded and welded sheet steel, impeller with forward curved blades made in galvanized sheet steel dynamically balanced, motor support (when present) made in welded sheet steel and steel sections.
- Pt = 5 - 140 mm. H2O - Q = 110 - 13.000 mc/h
- The fans of these 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.
- For all the fans of these ranges 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.
