RFBA EC external rotor motor


Radial fans “plug fan” with backward curved blades, direct driven with brushless motor and separate inverter

  • Fans with impeller to single inlet in metal or aluminium, optimized for noise and electrical absorption reduction from 250mm to 560mm size.
  • Without cochlea, replaced with a plenum for containment
  • Plug fan of last generation with high efficiency
  • Impeller with backward curved blades with air foil or metallic type directly assembled with the rotor of the motor, in order to reduce at its minimum the fan weight and in the same time to achieve a best air flow stability, European impeller of last generation
  • External rotor brushless motor of ultimate generation and separated inverter, (without magnet)  closed with IP44/55, with software overload control, in addition to the normal thermal protector normally closed
  • Continuous speed regulation by external signal 0-10Vdc or potentiometer (in option) for a manual regulation
  • Soft-start series
  • Habitual use: air treatments unit, rooftop units, heat exchanger, data centres
  • Max flow rate 20000 m³/h
  • Max static pressure 1400 Pa
