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.,
4.Only
5.Performance stated is at the rated power supply. Performance may vary as the power supply varies from the rated.
