A discharge gas manifold having a main conduit, an end feeder conduit, and at least one intermediate feeder conduit, wherein the at least one intermediate feeder conduit contains a portion, adjacent to the main conduit, that forms an angle between 0&#xb0;-60&#xb0; with the axis of the main conduit.

In an air terminal having an inflatable bellows expanding toward a pair of spaced cut-off plates, a sealing element is attached to the central portion of that side of the bellows adjacent to the cut-off plates. The transversely extending ends of the sealing element are not secured to the bellows but are free to separate therefrom as the bellows is expanded to thereby more easily engage the cut-off plates. A pair of foam strips are provided near the transverse ends of the sealing element so as to thereby provide a substantially normally extending surface against which the flowing air will impinge so as to thereby reduce the sound emanating therefrom. A pair of vibration damper clips extend from the cut-off plates and engage the foam strips to prevent any vibration thereof. Pads are secured to the edges of the cut-off plates so as to engage the seal element then thereby enhancing the sealing relationship between the cut-off plates and the seal element.

Air terminal apparatus

Low frequency noise and turbulence are reduced in a damper structure by providing a perforate screen extension onto the damper blade so as to extend across the flow path when the damper is open. Additionally, a perforate screen is located immediately downstream of the damper and spaced from the wall so as to define a chamber therewith as well as defining a boundary of the flow path.

Low frequency noise and turbulence reducer

A spoiler is located on the damper blade of a damper assembly such that it serves to divert the flow from the hinge area to avoid air separation. Further, the spoiler does not define the most restricted portion of the flow path and thereby has a minimal effect on the flow resistance.
