Abstract (en)

A noise and vibration reduction unit (101) comprises an air inlet (117), an elongate encasing body (108), a cancellation medium (121) and an air outlet (118). The inlet (117) allows influx of air from a compressor into an internal volume of the elongate encasing body (108) that is filled with the cancellation medium (121). The air passes through the cancellation medium (121) and the associated sound and vibrational disturbances that are produced by the compressor are dampened by the medium (121). The air then passes out of the elongate encasing body (108) by way of the air outlet (118) and is transferred downstream via tubing to an apparatus or environment for oxygen uptake.
