Patent ID: 7815012

Claim:
An air distributor, comprising: a first air duct extending in a first direction; a second air duct extending in a second direction; a joint between the first air duct and the second air duct; a body adapted for insertion at the joint and adapted to deflect an airflow in the first air duct into the second air duct; a plurality of perforations in the body adapted to pass a component of the airflow, the plurality of perforations located in an area of the body where the airflow initially impacts upon the air distributor, the plurality of perforations being configured such that the component of the airflow passing through the plurality of perforations generates small vortices thereby reducing low frequency noise generated by the airflow exiting from the first duct; a base end of the body that points into the first direction when in an installed position; and a first top end and a second top end of the body adapted to extend partially into the second air duct.
