The sileo series has backward-curved centrifugal impellers made of high-performance composite material with highly efficient, profiled 3D blade geometry. All models are equipped with vibration-free suspended, voltage-controllable external rotor motors. When operating DVS/DHS/DVSI sileo roof fans on a frequency converter, an all-pole sinusoidal filter must be used!
