The big advantage of the integrated fan compared to classic fan cooling is its compactness. Thanks to the integration of a special built-in motor, the otherwise built-up fan motor is no longer necessary. The fan motors often prove to be a nuisance when integrated into the machine and unnecessarily increase the machine's footprint. 

Internal ventilation is particularly suitable for applications with high overload or high effective torque and short cycle times, such as in blow molding machines or with servo-hydraulic drives.
