Table 5 — Blower Data — 50HQP072
LEGEND 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.
