4. Units factory shipped with standard static sheave and drive at 2.5 turns open
(8000 cfm at 0.5 in. wg ESP Wet Coil). Other speeds require field selection.
5. ISO/ARI rating point with standard static sheave and drive at 2 turns open
(8000 cfm at 0.6 in. wg ESP Wet Coil). Other speeds require field selection.
6. For applications requiring higher static pressures, contact your local
representative.
7. Performance data does not include drive losses and is based on sea level
conditions.
8. Do not operate in gray region.
9. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 208 v for
208-230-v units.
10. 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
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.
