Orion Fans has recently developed a low-cost dual channel phase control unit to control fan speed for single or multiple fan assemblies, series OA11/22.
It is field adjustable, with the ability to precisely control fan noise, speed, and air delivery according to application requirements. It also comes with four factory presets that allow for maximum flexibility with minimum setup.
Well suited for medical, industrial, networking, and telecom applications, the OA11/22 unit is designed for use with any AC fan or fan tray.
