LEGEND
NOTES:
1.
Unit is factory shipped with standard static sheave and drive at 2.5 turns open.
Other speeds require field selection.
2.
For applications requiring higher static pressures, contact your local Carrier rep-
resentative. Performance data does not include drive losses and is based on sea
level conditions.
3.
All airflow is rated at lowest voltage. If unit is dual voltage rated, data is based on
lowest voltage.
4.
A = Standard Rpm/Standard Motor, B = Low Rpm/Standard Motor, C = High
Rpm/Standard Motor, E = High Rpm/Large Motor.
