— Std Static - 440-609 RPM, Max BHP 1.9 (motor is 2.4 HP)
— Med Static - 547-757 RPM, Max BHP 2.9 (motor is 2.9 HP)
— High Static - 762-963 RPM, Max BHP 6.5* (motor is 5.0 HP)
BOLD — Field-supplied drive (motor pulley = KR11HY151, use belt and blower pulley from standard static), rpm range = 338-507
Italics Field-supplied drive (motor pulley = KR11HY186, blower pulley = KR51BJ413, belt = KR30BE072, use medium static motor),
—
rpm range = 684-864
* On Size 12 units, Max BHP for the High-Static High-Efficiency motor varies with the motor's voltage; see the table below.
