Ve loc ity Lim i ta tions for Var i ous Ap pli ca tions
The sound caused by an air outlet in operation is directly proportional to the
velocity of the air passing through it. As air velocity increases, so does the
noise level.
The following recommended outlet velocities are within the safe sound
limits for most applications.
