The Alpenföhn Föhn 120 Wing Boost is impressively specified and contains a few innovations that should hopefully translate into a good performance.
a.) Anti-vibration elements:
Using the injected anti-vibration element noise generated by vibrations is reduced to a minimum.
The fan frame is covered with a thin rubber layer to additionally reduce vibrations.
By using the aerodynamically optimized WB-technology (wing boost technology) the Föhn120 WB operates at lowest noise even running at 1500 rpm.
The new developed HD bearing (hydraulic bearing) reduces the friction noise to a minimum.
Guaranteed operating range:
With the guaranteed operating range from 5 – 12 VDC the new Föhn120 WB can be ideally used as a case fan.
