Crowley Co.'s Multi-Wing X Series fans have a twisted airfoil blade profile design that attains a condition of high air volume, low power consumption and low noise. Thermoplas-tic blades and die cast aluminum hubs are one-third the weight of a steel fan, resulting in less wear and stress on motors and bearings. X Series fans are available in diameters from 36 to 78", four corrosion-resistant blade materials, configurations from three to 10 blades and pitchs angles from 25 to 50o.
