NOTES:
1. Minimum air throw refers to the distance from the diffuser where the air ve-
locity is 150 fpm. In maximum air throw, this velocity has dropped to 50 fpm.
2. Data is based on an area with a 9-ft ceiling. For higher ceilings, values may
be reduced by one foot for each foot of height increase. For specific instal-
lations, minimum values can be reduced if properly qualified. Values are
dependent on cfm only and are not affected by duct pressure.
The optimum air throw values given in the table are dis-
tances from the unit centerline to the outside wall or nearest
obstruction (wall, light fixture or opposing air stream).
