BLOWER DATA
102S (CAV) AND 120S (STAGED) STANDARD EFFICIENCY BELT DRIVE BLOWER − BASE UNIT
BLOWER TABLE INCLUDES RESISTANCE FOR BASE UNIT ONLY (NO HEAT SECTION) WITH DRY INDOOR COIL AND AIR
FILTERS IN PLACE. FOR ALL UNITS ADD:
1 − Wet indoor coil air resistance of selected unit.
2 − Any factory installed options air resistance (heat section, economizer, etc.)
3 − Any eld installed accessories air resistance (duct resistance, diffuser, etc.)
Then determine from blower table blower motor output required.
See page 17 for blower motors and drives.
See page 17 for wet coil and option/accessory air resistance data.
