NOTES:

1. Shaded areas denote ESP where operation is not recommended.
2. Units factory shipped on medium speed. Other speeds require field

selection.

3. All airflow is rated and shown above at the lower voltage if unit is dual

voltage rated, e.g., 208 v for 208/230 v units.

4. Only two-speed fan (high and medium) available on 575 v units.
5. Data for units 006-012 not available at time of printing.

PSC Blower Motor Performance Data for 50PS Units with HWR

LEGEND

NOTES:

1. For units with HWR coil applications, calculate face velocity of the enter-

ing air. From the data table, find ESP for reheat application. The loss
includes wet coil loss.

2. Data for units 006-012 not available at time of printing.
