S20 20Nm Fail-Safe Spring Return Rotary Damper Actuator

The Honeywell spring return direct-coupled damper actuators provide modulating and floating control for air dampers, VAV units, Air handlers, Ventilation flaps, Louvers & reliable control for air damper applications with up to 1.5 m2 / 16 sq.ft (10 Nm / 88 lb-in) or 4.6 m2 / 50 sq.ft. (20 Nm / 177 lb-in) (Seal-less dampers; air friction dependent). Damper Actuators are easy to install with a self-centering shaft adapter that provides mounting flexibility and a greater clamping force. Detachable access cover allows direct wiring without a junction box, Stock less with the signal mode switch that adapts models to two-position, floating, or modulating applications. Direct-coupled damper actuators increased flexibility with select models available with/without three foot actuator whips & Sylk communications available on low-, medium- and high-torque DCAs.
