All Units have been tested in accordance with ANSI / ASHRAE 70-2006. Data in table is derived from such testing.2. Ps – Static pressure required to obtain listed cfm, units of inches water gauge (in. wg.).3. NC- Calculated noise criteria using 10 dB per octave room attenuation (dimensionless).4. Throw – Non-isothermal throw, in feet, for a terminal velocity of 50 fpm.5. For reverse size grilles use the performance as per the example below:6. Example: 10 X 24 use the performance for a 24 X 10.7. Inlet Velocity = fpm (Feet Per Minute).Additional engineering data is available upon request through your sales associate76 GRILLES, REGISTERS & DIFFUSERS
