Performance Notes
- 1) Throw value was measured in feet for a terminal velocity of 150/100/50 FPM.
- 2) Throw data is based on supply air and room air both at isothermal conditions.
- 3) Effective core areas listed in chart are defined as the measurement of space between the blades actually being utilized by the air.
- 4) Data obtained from tests conducted in accordance with ANSI/ASHRAE standard 70-2006.
