Audibly quieter
SilentVent

Noise is a high-grade environmental pollutant. This also
applies to the application of rail vehicles. But unlike with
cars, it is not the engine that creates the highest sound
levels at certain operating conditions, but the cooling
units and especially their fans.
Increasingly stricter exhaust regulations and growing output requirements call for higher and higher cooling performances; at the same time, the noise levels of the cooling
systems are expected to decrease. Two requirements that
fundamentally contradict each other! The SilentVent
meets them both: an axial fan with a completely new design combines aerodynamic characteristics with significant
noise reduction. Result: the quietest Voith fan of all times.
