PFP A3-0630 3F 5100W M6K8 BQE

The PFP is a backward curved blade fan equipped by an external permanent magnet rotor motor. The rotor
magnets are made by rare earths (NdFeB) that strongly reduce the motor dimension and, therefore, the fan
obstruction. The motor shape itself has been chosen for increasing the airflow inside the fan scroll.
The Driverisfully integrated into the motor and it drivesthe motorthrough a sensorless algorithm. The singlephase driver is equipped with an active PFC (Power Factor > 0.95 in any state of operation).
The Fans of series PFP combine high energy efficiency and low noise level. Thanks to the “EC” (electronic
commutation) motors, their electronicsintegrate speed control and protecting system. Thisreducesthe number of different components required to provide these functions, compared to fans with traditional motors.
The main feature of EC-motor is operating withoutslip losses, which allow consuming significantly less power
than conventional AC motors.
This occurs at all speed levels, especially with partial load operation. The EC complete drive system (i.e. the
combination of the permanent-magnet motor with its electronic driver) has a much higher energy efficiency,
in comparison with a drive system based on a conventional AC motor.
