R Reversible airfoil profile axial impellers

R impellers are manufactured assembling reversible profile blades made of aluminum, with a light aluminum alloy hub. The impellers are thought to be employed in applications with high temperatures and corrosive environments (i.e. drying rooms). The impellers are available in configurations with 5/9/12/16 blades both for clockwise and anticlockwise rotation. Blades are available with setting angles ranging from 20° to 45° and can produce a reversible air flow.
