摘要:
A modular fan cover assembly for inclusion on an electric motor is selectively configurable for degrees of reduced noise operation. The modular fan cover assembly includes a plurality of cooperating components arranged to direct fluid communication through the assembly. The components may include, for example, a fan cover defining a fan chamber for enclosing the fan, an inlet cover including an inlet chamber and a plurality of inlet apertures, and a silencing insert selectively includable with the fan cover assembly that may include one or more silencing features. The selective combination of the components can redirect airflow through various turns or bend in the modular fan cover assembly to trap or suppress noise propagating from the electric motor. The modular fan cover assembly may be operatively equipped with a blower assembly.
