Horton recently introduced its most efficient fan blade, the WindShift WSE, according to a company release. It has been computer-optimized to allow for increased airflow and reduced operating noise. The WSE is a swept-blade design that generates greater static pressure at slower speeds. The WindShift is suited for Tier 4 and Stage IV agricultural, construction, industrial, and power-generation equipment. The WindShift WSE Modular Fan is available in diameters of 24 to 41 in (610 to 1040 mm) and 2.44 to 5.94 in (62 to 151 mm) pitch widths. The WSC and WSD WindShift blades are engineered for low-restriction airflow applications, and fit narrower, more compact spaces. WindShift blades contain UV-stabilized materials, which have higher glass content than competitive products. Because of this design, they maintain strength and durability through a wider range of temperatures and operating conditions. WindShift fans are constructed with clamshell knuckles that clamp each blade to a 0.25-in (6-mm) steel center disk, allowing blades to be set to a specific pitch angle for increased airflow. Fans are offered in pitch widths ranging from 1.88 to 6.32 in (48 to 161 mm) and diameters from 24 to 52 in (610 to 1320 mm).
