Abstract

An air diffuser for an air distribution system comprising a first and a second border member. Plural spreaders interconnect the first and second border members thereby defining an airflow aperture therebetween. A pattern controller is slidably disposed between the plural spreaders for controlling the volume of airflow through the airflow aperture. The pattern controller is pivotable within the airflow aperture for controlling the direction of airflow through the airflow aperture.
