Performance Notes:

  1. Performance data is presented for the Prodigy® diffuser at several modulated inner cone positions with constant duct static pressures of 0.10, 0.20, 0.30 and 0.40 inches w.g..
  2. Air flow is in cubic feet per minute, cfm.
  3. Throw is in feet at terminal velocities of 150, 100 and 50 fpm.
  4. Throw data is based on supply air and room air being at isothermal conditions.
  5. NC is based on 10 dB room absorption. Blanks indicated a value of less than 15.
  6. Tested in accordance with ASHRAE Standard 70-1991 “Method of testing for Rating the Performance of AIr Outlets and Inlets.”
