Table 9 — 50PCH,PCV Blower Performance — Standard Unit
NOTES:
1. Shaded areas denote ESP (external static pressure) 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 lowest voltage if unit is dual volt-
age rated, i.e., 208-v for 208/230-v units.
4. Only two-speed fan (Hi and Med) available on 575-v units.
5. Performance stated is at the rated power supply. Performance may vary
as the power supply varies from the rated.
