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.
