ACmaxx / i-maxx

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, facil-

itate the transition to the new technology by retaining the overall mount-

ing dimensions. In short, to ensure the fans can be replaced 1:1 without

any peripheral changes or changes to the voltage situation.

ebm-papst offers two generations of ACmaxx products that meet different

needs.

Long service life

The efficiency of ACmaxx and i-maxx motors is up to 75% higher than that

of conventional AC fan variants. This not only saves energy, it also means

less intrinsic heating in the motor. The reduced heating has a direct, positi-

ve effect on the bearing system, which is why the fans have a service life

that is up to 85% longer! This also lengthens the service and maintenance

intervals significantly. The expense of replacement fans, and even more

expensive downtimes, are kept to a manageable minimum.

What ACmaxx and i-maxx have in common:

Energy efficiency

The drive concept is based on state-of-the-art GreenTech EC technology

with outstanding motor efficiency. Compared to AC fans of the same size,

ACmaxx energy consumption is up to 77% lower–for higher cooling capa-

city! The energy balance alone means that the products pay for themsel-

ves after only a few months. The savings over the entire service life, espe-

cially in systems with multiple fans, is considerable.

Independent of mains frequency and mains voltage

The ACmaxx and i-maxx fans are prepared for direct connection to all AC

voltages and frequencies. The speed, and thus important properties of the

fan such as air flow and noise, are independent of the power frequency

and do not change, even within the defined voltage range. Voltage fluctua-

tions in the power system are automatically compensated for.
