Abstract
A round or rectangular ceiling diffuser includes a blade. The blade includes a leading edge configured to face an incoming air flow and having an undulated contour extending along a closed-loop formed by the blade. The blade also includes a trailing edge opposite to the leading edge, where a width of the blade extends from the leading edge to the trailing edge and the undulated contour extends into and out of the width.
