LEGEND
—— Operation Not Recommended BkW — Brake Kilowatts
ESP — External Static Pressure RPM — Revolutions Per Minute
A — Units with Standard Rpm/Standard Motor Option B — Units with Low Rpm/Standard Motor Option
C — Units with High Rpm/Standard Motor Option
NOTES:
1.A = Standard Rpm/Standard Motor, B = Low Rpm/Standard Motor, C = High Rpm/Standard Motor.
2.Unit factory shipped with standard static sheave and drive at 2.5 turns open. Other speed require field selection.
3.For applications requiring higher static pressures, contact your local rep- resentative. Performance data does not include drive losses and is based on sea level conditions.
4.All airflow is rated at lowest voltage if unit is dual voltage rated, i.e., 380V for 380/420V units.
5.Airflow in l/s with wet coil and clean filter.
