GENERAL
 

These direct-coupled damper actuators provide two-position and floating control for:

• air dampers,

• VAV units,

• air handlers,

• ventilation flaps,

• louvers, and

• reliable control for air damper applications with up to

4.6 m2 / 50 sq.ft. (20 Nm / 177 lb-in) or 7.8 m2 / 85 sq. ft.

(34 Nm / 300 lb-in) (seal-less dampers; air frictiondependent
