Horton has introduced WindShift modular fans for the off-highway, industrial and other specialty markets. According to Horton, this line of fans provides versatility in design and manufacturing for a myriad of applications and optimal fan drive cooling. The modular fans have clamshell knuckles that clamp the blades at precise pitch angles. According to the company, this feature offers flexibility for customers’ specifications and speeds the testing and prototyping stages. If testing shows that a different pitch angle or blade configuration provides more optimized cooling for a specific application, the knuckle clamp feature allows easy modification of the fan design.
The clamshell knuckles clamp each blade to a 0.25-in. (6 mm) steel center disk. Customers specify blade configuration and pitch angle, center disk diameter and rotation. Equally spaced blade configuration options are offered with 6, 7, 8, 9, 11 or 13 blades. Staggered blade configurations, which help to reduce noise, are available upon request. Pitch width ranges from 3.08 in. (78 mm) to 6.32 in. (161 mm). Fan diameter ranges from 30 in. to 48 in. (762mm to 1,219 mm). Fans are available in clockwise and counterclockwise rotation. Standard pilots range from 1 in. (25 millimeters) to 5 in. (25 mm to 127 mm). Maximum tip speed is 18,000 ft. per minute (91 m per second).
WindShift modular fans are compatible with all Horton and competitive viscous fan drives and are initially available for first-fit applications.
