Primary air valve is closed and therefore primary cfm is zero.
Performance Notes for Sound Power Levels:
1. Discharge (external) static pressure is 0.25" w.g. (63 Pa) in
all cases, which is the difference (∆Ps) in static pressure
from terminal discharge to the room.
Discharge Sound Power Levels (SWL) now include
duct end reflection energy as part of the standard
rating. Including the duct end correction provides sound
power levels that would normally be transmitted into an
acoustically, non-reflective duct. The effect of including
the energy correction to the discharge SWL, is higher
sound power levels when compared to previous AHRI
certified data. For more information on duct end reflection
calculations see AHRI Standard 880.
2. Radiated sound power is the breakout noise transmitted
through the unit casing walls.
3. Sound power levels are in decibels, dB re 10

Ratings are certified in
accordance with AHRI
Standards.
4. All sound data listed by octave bands is raw data without
any corrections for room absorption or duct attenuation.
Dash (-) in space indicates sound power level is less than
20 dB or equal to background.
5. Min. inlet ∆Ps is the minimum operating pressure of the
primary air valve section.
6. Asterisk (*) in space indicates that the minimum inlet static
pressure requirement is greater than 0.5" w.g. (125 Pa) at
rated airflow.
7. Data derived from independent tests conducted in
accordance with ANSI / ASHRAE Standard 130 and AHRI
Standard 880.
