RFB-SISW Motore EC Rot Est


Radial fans “plug fan” with backward curved impeller, direct driven with external rotor brushless motor with on-board inverter

  • Fans with single inlet plastic impeller, optimized for low noise emission up to 225mm size and impeller in galvanized steel for larger sizes
  • No need of housing, replaced by the plenum manufactured by the OEM or the final user
  • Backward curved plastic impeller airfoil type or metallic type directly assembled with the rotor of the motor, in order to reduce at its minimum the fan weight and increase air flow stability
  • External rotor brushless motor with last generation integrated driver, without the dependence from extremely rare magnets avoiding difficulties in worldwide availability ( rare earth ), closed type IP44/55, equipped with software monitoring any overload condition, working in parallel with the common normally closed thermal protector
  • 0-100% speed regulation, with external signal 0-10Vdc o manual potentiometer ( accessory currently available )
  • Soft-start setting allowing smooth operation
  • Max flow rate 5000 m3/h
  • Max static pressure 1000 Pa
