The NEW A fans are manufactures assembling variable pitch, wide-chord airfoil profile blades with a light aluminum alloy hub. The fans are the best choice for applications which demand high air-flows at medium/low rpm. A fans are extremely durable, efficient and low-noise. The fans can have 3/4/5/6/8 blades configurations both for clockwise and anticlockwise rotation and can produce a sucking or blowing air flow. A blades are available with right or left fixed setting angles ranging from 15° to 35°.
