50RHC,RVC BLOWER PERFORMANCE
*Size 006 available in 50RHC unit only.
†Size 041 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 (HI and MED) 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 velocities of 200 fpm
increase the static pressure 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 dry coil and clean air filter.
