3. Units factory shipped with standard static sheave and drive at 2.5 turns open (3500 cfm
at 0.7 in. wg ESP Wet Coil). Other speeds require field selection.
4. ISO/ARI rating point with standard static sheave and drive at 3.5 turns open (3500 cfm
at 0.45 in. wg ESP Wet Coil). Other speeds require field selection.
5. For applications requiring higher static pressures, contact your local representative.
6. Performance data does not include drive losses and is based on sea level conditions.
7. Do not operate in gray region.
8. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 208 v for 208-230-v
units.
9. 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.
