Nicotra ventilator radial ErP 2015 DDM10/8 230V/1/50Hz

DDM series – with direct drive motor
The radial fans in the DDM series with integrated external rotor motor and impeller drum are the ideal solution for demanding heating, ventilation and air conditioning (HVAC) applications. Directly driven radial fans, double inlet, with forward curving blades.

Compact housing
Aerodynamic with an optimised spiral design housing made from galvanised sheet steel. Produced using a special automated method, tough and durable.
• no welded points - no problems with corrosion
• high-precision production method for high-quality products

Effective drum rotor
The impeller drum is optimised for high efficiency and is specially adapted to the properties of the integrated motor. The durability of the impeller is the result of our innovative and automated production method.

Optimised external rotor motor
The external motor with directly attached high-performance impeller is optimally cooled by the flow of air through the fan. Speed can be controlled via a transformer of electric device (TRIAC). Motors are protected by thermal relays as standard to prevent overheating.

Vibration insulation
The vibration insulated motor mount ensures a low noise emissions from the fan and prevents mechanical vibrations being transferred to the fan housing.

Simple electrical connection
The fans are fitted with a terminal box, strip or loose cables. Electrical connection is simple using the included circuit diagram.
