This SEPA
®
high-tech miniature fan is suitable for industrial or automotive use and has a remarkable air
flow performance despite its small dimensions. Due to a nearly linear air performance characteristic, the
fan is applicable for different uses. 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 rigid plastic housing of PBT (UL
E54695), ball bearings with narrow tolerances of special steel, polyester-based PCB (UL E44247) and
absolute reliability due to 100% burn-in.
