The new Nicotra Gebhardt DDM is a scroll casing fan with direct drive and forward curved blades - double inlet. The new DDMP is driven by a particularly energy-efficient compact EC motor. These innovative EC motors operates without slip losses and uses less power than the AC motor under all operating conditions and has a significantly higher level of drive system (motor and control) efficiency.
