ACmaxx / GreenTech EC-Compact fans Technical information Overview Axial fans ACmaxx / GreenTech EC-compact fans

ACmaxx / GreenTech EC-compact fans Technical information Progress made by ebm-papst The best example: The ACmaxx fans from ebm-papst, which, thanks to an ingenious yet simple improvement over conventional AC fans, provide substantial benefits. The aim in developing the new ACmaxx series was to raise the technology standard of the conventional AC fan significantly and, in the process, facilitate the transition to the new technology by retaining the overall mounting dimensions. In short, to ensure the fans can be replaced 1:1 without any peripheral changes or changes to the voltage situation....

GreenTech EC-compact fan is more efficient! ACmaxx saves energy, and the GreenTech EC-compact fan generation saves even more. While an AC fan at 50 Hz can barely reach an overall efficiency of 5-6%, the ACmaxx makes it to approx. 20-25%. With the new GreenTech EC-compact fans ACi 4400, a remarkable level of up to 30% is reached. This is the result of the optimisation of the entire package made up of drive, electronics, AC/DC conversion and aerodynamics. Thus the new GreenTech EC-compact fans series boasts energy savings of almost 75% compared to the corresponding AC fan, thus providing...

ACmaxx / GreenTech EC-compact fans Technical information Particular design features of the ACmaxx: Prepared for all AC voltages These types have a very wide voltage range from 85 to 265 VAC – the global voltage range, so to speak. This enables the fan to be used around the world, opening up large savings potentials. In addition to reduced logistics effort and stock-keeping, worldwide availability is key. ACmaxx is compatible with every supply voltage–no switching needed. From 85 to 265 volts and mains frequencies of 50 and 60 hertz. Voltage fluctuations in the power system are automatically...
