These SEPA
®
high-tech miniature fans are suitable for industrial or automotive use with very low power
consumption and have a remarkable air flow performance despite its small dimensions and very low
power consumption. Due to a nearly linear air performance characteristic, the fans are applicable for
different uses. They are permanently protected electrically against reverse polarity, blocking and thermal
overloading. Due to the low rotor weight and precision balancing, they are virtually vibration-free. They
are also insensitive to shock.
Further features of these fans are there 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.
