50HQP072 BLOWER DATA

LEGEND

NOTES:

1. Units factory shipped with standard static sheave and drive at 2.5 turns open

(2400 cfm at 0.5 in. wg ESP Wet Coil). Other speeds require field selection.

2. ISO/AHRI 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.

3. For applications requiring higher static pressures, contact your local

representative.

4. Based on standard 12x12 blower.

5. Performance data does not include drive losses and is based on sea level

conditions.

6. All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 208 V for

208-230 V units.

7. 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.

8. Large motor size is 2 hp for 50HQP072.
