ACmaxx / i-maxx
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, 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.

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.
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.

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.
