Abstract

The present invention is related to a fan silencer that attenuates the continuously fluctuating sound waves without being propagated and that lowers the acoustic energy emerging in the near field, within the hydrodynamic near field of the suction fan particularly used in electrical vacuum cleaner motors. The silencer essentially consists of an annular set (13) surrounding the suction fan (2) which forms a barrier between the suction fan and the fan clow side wall (12). On this set (13) exist one or more than one rows of circular holes (8). The silencer (7) can be fixed inside the suction fan cover (3) or on the surface (14) of the air diffuser (6) that faces the suction fan.
