Abstract

An apparatus for reducing distortion of air flow entering the inlet (16) of a fan (10). The device includes a perforated body member (32) that has a first end (34) that is attachable to the inlet end 916) of the fan (10) and a second end (36). The apertures in the body member (32) are arranged in a plurality of circumferential rows. Preferably, the apertures in each successive row from the first end (34) to the second end (36) increase in diameter with the apertures in the row adjacent the first end being smaller in diameter than the apertures in the row adjacent the second end. The body member (32) can be frustoconical, cylindrical or ellipsoidal in shape. In addition, the body member (32) can be equipped with an apparatus for reducing airflow noise.
