The large use of AC Plenum Fans with direct driven motor (Arr.4) dominates the actual HVAC market, thanks to its very smart and compact solution for most current applications. The need of VFD (Variable Frequency Drive) is compulsory in most cases in order to match the motor speed with fan speed for the desired duty point.

However, there are many requests of AC Plenum Fans with no VFD in the market whereas it is very difficult to match motor and fan speed by using standard wheels.

It consist of giving 10 different speeds with the same wheel just by reducing the blade width from 100% down to 50%. This huge flexibility almost always allows to match the motor speed in both 50Hz and 60Hz.

Here below, as an example, NPA 500 PW looked in 2 different meanings:

  1. Range of performances allowed by NPA500 from 95% to 50% blade width
  2. Aeolus software selection with the different choices with same Fan NPA 500
    Aeolus4 NPA Partial Width

NPA Partial Width 100% - 80% - 60% - 50%
