TAA240 BLOWER PERFORMANCE

All data is measured external to the unit with dry coil and standard 2 in. air filters in place.
FOR ALL UNITS ADD:
1 − Wet indoor coil air resistance of selected unit.
2 − Any field installed accessories air resistance (electric heat, economizer, etc.) See page 14.
Then determine from table the blower motor hp and drive rpm required. See page 12 for blower drive specifications.
