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

 

  • Fans with single inlet metal or aluminium impeller, optimized for low noise emission up from 250mm to 560mm size.  
  • No need of housing, replaced by the plenum manufactured by the OEM or the final user
  • Backward curved metal or aluminium impeller airfoil type assembled on the tree of the motor, in order to reduce at its minimum the fan weight and increase air flow stability
  • Brushless motor with last generation of separated 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
  • Application in the market: air treatments unit, rooftop units, recuperator, data centers
  • Max flow rate 20000 m3/h  
  • Max static pressure 1400 Pa
