WindShift fans have clamshell knuckles that clamp the blades at precise pitch angles. This feature offers flexibility for users' specifications and speeds the testing and prototyping stages. The clamshell knuckles clamp each blade to a 0.25". The user specifies 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, also are available. Pitch width ranges from 3.08 to 6.32" (78 to 161 mm). Fan diameter ranges from 30 to 48" (762 to 1,219 mm). Fans are available in clockwise and counterclockwise rotation.
