IE3-class blower motors for industrial plants, commercial buildings and HVAC fans; low noise, long life and easy speed control with a drive.
High-Efficiency AC Blower Motor
Fan motors run for most of the day in most plants, so the efficiency class decides the total cost of ownership. MST Motor's high-efficiency blower motors meet the national energy-efficiency standards and deliver a clear saving over conventional motors.
Three parameters drive the selection: efficiency class, power and speed matched to the fan load, and a protection class suited to the environment. The values below belong to a 160 kW 4-pole model from a customer delivery.
- Applications — industrial ventilation, HVAC, cooling towers, boiler forced- and induced-draught fans
- Drive compatibility — extra savings by matching airflow to demand
