Farm building fan FPowlet

for air circulationaxial

Description
The FPowlet axial fan is designed for integration into heat pumps and delivers low acoustic emissions thanks to a biomimetic blade concept. The blade combines a serrated trailing edge, a rippled leading edge and an owl-wing-inspired winglet, forming a blade geometry unique to this series.

Product specification
The FPowlet axial fan merges blades developed for refrigeration applications with an explicit acoustic focus for heat pump use. The rotor is paired with ECblue external-rotor motors featuring integrated controllers, enabling 100% speed control to set the optimal operating point. Two-level dynamic balancing provides smooth operation and extended service life, positioning the FPowlet for use in high-efficiency heat pump systems.
