The KV DUO fans are driven by EC-external rotor motors. These are energy saving motors with high efficiency. The power electronics are integrated in the motor housing. All models have one potential-free terminal for error message. All motors are suitable to be used for 50/60Hz. The input voltage for single phase units can vary between 200 and 277V, for three phase units between 380 and 480V. Speed control by a 0-10V signal.

The fans are easy to connect to spiral ducts using FK mounting clamps. The KV DUO models are manufactured from Aluzinc sheet steel with acoustic insulation and are suitable for external mounting on roofs. All models are equipped with backward curved centrifugal impellers wired out to an IP65 Terminal box.
