Horton Introduces WindShift(TM) Modular Fans

WindShift fans provide flexibility and expedites testing and prototyping

ROSEVILLE, Minn.-Horton has introduced its first modular fans-WindShift Modular Fans for the off-highway, industrial and other specialty markets. This line of fans provides significant versatility in design and manufacturing for a myriad of applications and optimal fan drive cooling. WindShift Modular Fans have innovative clamshell knuckles that clamp the blades at precise pitch angles. This feature offers flexibility for customers' specifications and speeds the testing and prototyping stages.

"The blade design is computer optimized to provide efficient cooling," says Neal Shawaluk, director of sales for off-highway, industrial and specialty markets at Horton. "If testing shows that a different pitch angle or blade configuration provides more optimized cooling for a specific application, the knuckle clamp feature allows us to easily modify the fan design. This flexibility ensures that significantly less time is spent on testing, prototyping-and manufacturing, without sacrificing performance."

WindShift Modular Fans' clamshell knuckles clamp each blade to a 0.25-inch (6 millimeters) 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 inches (78 millimeters) to 6.32 inches (161 millimeters). Fan diameter ranges from 30 inches (762 millimeters) to 48 inches (1219 millimeters). Fans are available in clockwise and counterclockwise rotation. Standard pilots range from 1 inch (25 millimeters) to 5 inches (127 millimeters). Maximum tip speed is 18,000 feet per minute (91 meters per second).

WindShift Modular Fans are compatible with all Horton and competitive viscous fan drives and are initially available for first-fit applications.
