This 

®

 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, block-
ing and thermal overloading (by IC). Due to the low rotor weight and precision balancing, it is virtually vi-
bration-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.
