This SEPA
®
high-tech miniature fan is suitable for industrial or automotive use and has a remarkable air flow
performance despite its small dimensions. Thanks to the extremely low power input, this fan is highly suitable for
battery-operated devices. It is permanently protected electrically against reverse polarity, blocking and thermal
overloading. Due to the low rotor weight and precision balancing, it is virtually vibration-free. It is also insensitive to
shock.
Further features of this fan are its extremely robust and torsionally stiff plastic housing of PBT, ball bearings with
narrow tolerances, of special steel, polyester-based PCB and absolute reliability due to a 100% burn-in.
