B3P190 compact fans use a high-performance EC motor based on the technology of homogeneous plate magnets, thanks to which the fan has a high operating culture and generates low noise even at low rotational speed. The new motor design also increased its efficiency by as much as 21% compared to the current available model. The fan is designed for use in devices with limited space, and its installation is suitable for compact device chambers.
