Description
Performance Notes: 1. Projection and Spread data were determined in a room with a 10’ceiling height and 10°F ΔT, between supply air and averaged occupied room temperature. 2. Vertical projection (throw) is the maximum height above the floor where terminal velocities of 150,100 & 50fpm were observed. 3. Horizontal Spread is the total width of the isovel where terminal velocities of 150, 100, and 50fpm were observed. 4. Noise Criteria (values) based on 10 dB room absorption, re 10-12 watts. 6. Pressure is in inches w.g. 5. Tests conducted with Damper fully open. 7. Test conducted according to ASHRAE 70 StdROUND FLOOR DIFFUSER-MODEL RFD
