Table 6 — Fan Rpm at Motor Pulley Settings*
*Approximate fan rpm shown.
†Indicates standard motor and drive package.
**Indicates alternate drive package only.
††Indicates high-static motor and drive package.
***Indicates alternate motor and drive package.
Table 7 — Evaporator-Fan Motor Efficiency
NOTE: Convert bhp to watts using the following formula:
Table 8 — Accessory/FIOP Static Pressure* (in. wg)
LEGEND *The static pressure must be added to external static pressure. The
sum and the evaporator entering-air cfm should then be used in con-
junction with the Fan Performance tables to determine blower rpm and
watts.
