*Actuator is spring-return type.

NOTES:

1.All actuators are direct coupled type, designed to be directly mounted into jackshaft assembly.

2.All actuators are equipped with a plenum rated cable, factory- terminated to the actuator. Part No. HF27BB035 and 034 are 16 ft, HF27BB033 is 9.5 ft.

3.Damper areas are nominal and based on low leakage type dampers.

4.For larger damper assemblies, multiple activators may be used.

5.Part No. HF27BB033 and 034 are designed for inlet guide vane and face and bypass applications, but may be used for external relief dampers if spring return is not required.

NOTES:

1.Hand is determined by the location of the fan drive and/or coil connection when viewed while facing the direction toward which air is flowing.

2.Dimensions in ( ) are in millimeters.
