*All throw measurements are made from the center of the grille to a terminal velocity of 50 feet per minute. Direction determined by grille profile. .
**Noise level of any diffuser is directly related to face velocity. As a general rule face velocity should be under 800 FPM for residential applications.
The MV diffuser with its one piece molded design, outperforms comparable diffusers causing less turbulence and noise.
