Abstract (en)
[origin: EP2626644A1] The ventilation device has channel shaped structure provided with circumferentially spaced housing walls (1). The housing is provided with radial fan (2) that is arranged along flow direction (4) upstream of aperture (5). The aperture is provided with opening (6) through which medium is passed to radial fan. The sound insulation and sound damping material is provided in housing walls such that lower acoustic power is circulated through aperture along the flow direction upstream of housing walls by releasing flow channel.
