Vari-Green Drive (Model VGD-100) is a factory-mounted and wired variable speed control for three-phase motors up to 10HP. Internally mounted within the fan housing, the drive virtually eliminates voltage spikes that can contribute to motor performance issues and failure.
The preprogrammed drive uses R3 filtering technology to significantly reduce electrical harmonics. The solution optimizes energy savings and efficiency of ventilation systems in a variety of applications.
