Table 9 — 50RHC,RVC Blower Performance
*Size 006 is available in 50RHC unit only.
†Size 041 is available in 50RVC unit only.
NOTES:
1. Gray areas denote ESP (external static pressure) where operation is not
recommended.
2. Units factory shipped on medium speed. Other speeds require field
selection.
3. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 208 v
for 208-230 v units.
4. All units ARI/ISO/ASHRAE 13256-1 rated on high fan speed.
5. Only two-speed fan (H & M) available on 575-v units.
6. For wet coil performance first calculate the face velocity of the air
coil (Face Velocity [fpm] = Airflow [cfm]/Face Area [sq ft]). Then for veloci-
ties of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by
0.08 in. wg, 400 fpm by 0.12 in. wg, and 500 fpm by 0.16 in. wg.
7. Airflow in cfm with net dry coil and clean air filter.
