Table 10 — 45K Series Fan Powered Terminal Unit Performance
a,b,c
NOTE(S):
a. 45K maximum primary airflow (cfm) is set by the maximum induced airflow, which may vary as a function of downstream pressure. Maximum airflow shown is based on
the maximum induced airflow (fan airflow) or 1.00 in. wg differential pressure signal from inlet airflow sensor, whichever is less.
b. Minimum recommended primary airflow (cfm) is based on 0.03 in. wg differential pressure of the inlet airflow sensor, or 0 airflow. 0.03 in. wg is equal to 15% to 20% of
the nominal flow rating of the terminal. Less than 15% to 20% may result in greater than +5% control of box flow.
c. 45K maximum/minimum fan airflow is based on 0.10 in. wg / 0.60 in. wg downstream static pressure, respectively.
