Unit factory shipped with standard static sheave and drive at 2.5 turns open. Other speed require field selection.
For applications requiring higher static pressures, contact your local representative. Performance data does not include drive losses and is based on sea level conditions. Do not operate in black regions. All airflow in rated at lowest
Voltage if unit is dual Voltage rated, i.e. 208V for 208-230V units.
For dry coil performance first calculate the face velocity of the air coil (Face Velocity [FPM] = Airflow [CFM] / Face Area [sqft]).Then use preceding wet coil to dry coil conversion table.
All Data is Wet Coil
