Table 10 — 45K Series Fan Powered Terminal Unit Performance
NOTES:
1. 45K maximum primary airflow (cfm) is set by the maximum induced air-
flow, which may vary as a function of downstream pressure. Maximum air-
flow 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.
2. Minimum recommended primary airflow (cfm) is based on 0.03 in. wg dif-
ferential 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.
3. 45K maximum/minimum fan airflow is based on 0.10 in. wg / 0.60 in. wg
downstream static pressure, respectively.
