TM impellers are manufactured assembling airfoil profile blades with a light aluminum alloy hub. The impellers are thought to be employed in applications that require the highest rotation speeds. The impellers are available in configurations with 5/9/12/16 blades both for clockwise and anticlockwise rotation. Blades are available in two models: N and V, with right or left setting angles ranging from 20° to 50°. TM impellers can produce a sucking or blowing air fl ow.
