Applications
355mm EC Electric plenum centrifugal fan
Special Features:
Energy saving.
Direct drive EC plug fans are significantly more efficient than equivalent AC motor belt drive fans. Over the full and part load operating spectrum, the EC plug fan is up to 20% more efficient than a standard induction motor, variable speed, belt driven fan.
Lower sound level.
Commutation and stator design make for low-noise magnetisation of the exciter field. This results in a acoustically imperceptible high cycle frequency.
Wide fan speed.
EC fan can be operated on 0-100% capacity using a 0-10V dc control signal, whereby the fan speed can be continuously variable.
