Ambient influences

AC fans are extremely common and are used in a wide variety of applica-

tions. In control cabinet cooling, beer coolers, cooling cabinets, wood-bur-

ning stoves, medical devices – all have different requirements for resi-

stance to ambient influences. ACmaxx and i-maxx fans offer the same

features for protection against moisture, splash water and rough ambient

conditions.

Particular design features of the i-maxx (ACi 4400):

i-maxx is more compact!

As large as existing AC fans – and not a bit larger. This is the most out-

standing feature of the new i-maxx ACi 4400. Even in the hub area, the

fan does not differ from typical 119x119x38 mm AC fans. Out with the

AC, in with the i-maxx ACi 4400 – it's that simple.

i-maxx is more efficient!

ACmaxx saves energy, and the i-maxx 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 i-maxx ACi 4400, a

remarkable level of up to 30% is reached. This is the result of the optimi-

sation of the entire package made up of drive, electronics, AC/DC conver-

sion and aerodynamics. Thus the new i-maxx series boasts energy savings

of almost 75% compared to the corresponding AC fan, thus providing signi-

ficantly higher savings than the 40% level of the old AC 4300 generation.

i-maxx is quieter!

The i-maxx ACi 4400 is quieter! Quieter than AC fans and quieter than the

existing ACmaxx generation. The reason for this is the optimised aerody-

namics and the drive, which is optimised for minimum structure-borne

noise. Thus the fan is only half as loud at comparable air performance,

and is up to 6 dB(A) quieter at some operating points.

Speed independent of voltage and frequency

For the i-maxx ACi 4400, the speed, and thus the air flow and operating

noise, are independent of the supply voltage and power frequency.

Versions are available for 115 VAC with a voltage range from 85 to 132

VAC and 230 VAC with a voltage range of 195 to 265 VAC. Voltage fluctua-

tions and frequency differences in the power system are compensated for

automatically.
