Abstract
A plug or plenum fan is located near two walls of the plenum such that they tend to act as the scroll for the fan. Additionally, a partition separates the fan from an adjacent corner further enhancing the formation of a scroll while providing a flow passage and a location for at least a part of the active noise control structure.
