Tubeaxial Fans
Chicago's Design 37 Direct Drive Tubeaxial Fans with adjustable pitch blades are capable of more air delivery for the same horsepower. Efficiencies exceeding 70% are common. How? The primary reason for increased efficiency is Chicago's unique blade design. The entire length of the blade surface generates air flow, not just the tip alone. The air flow is uniform all along the blade.
