    Note: Air outlet test length is based on 1M.
    Note: Reach distance is measured at terminal air speed of 0.5M/S~0.25M/S.
    Note: NC value column [-] indicates NC is below 20.
    Note: NC value is based on indoor absorption attenuation of 10dB and 10-12 watts.
    Note: Tested according to A.D.C. standard.
    Note: If used for return air, static pressure loss = total pressure loss * 0.75 and NC value + 5.
    Note: When the length changes, the reach distance and NC correction values are as follows:
