3. ISO/ARI rating point with standard static sheave and drive at
3.5 turns open (2400 cfm at 0.5 in. wg ESP Wet Coil). Other
speeds require field selection.
4. For applications requiring higher static pressures, contact your local
representative.
5. Based on 12x11 blower.
6. Performance data does not include drive losses and is based on
sea level conditions.
7. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e.,
208 V for 208-230 V units.
8. 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.
9. Large motor size is 2 hp for 50HQL072 and 3 hp for 50HQL096.
