D-3062-1 Johnson Controls Damper Actuator

Datasheet

The Johnson Controls D-3062-1 Damper Actuator 3-7#; 2″ STROKE; SR; FOR 4SQFT DMPR MAX

When used with proportional control, the damper size is limited to 4 square feet maximum.

As a 2-position control, damper size is limited to 6.25 square feet. As determined by testing using Johnson Controls D-1300 dampers, width and height are limited to 30 inches maximum.

Four nominal spring ranges are available: 3-7 psi (D-3062-1), 5-10 psi (D-3062-2), 8-13 psi (D-3062-3), and 11-15 psi (D-3062-4).

The control air pressure for normal HVAC operation is 0-20 psig. The minimum control pressure for safety damper ventilation mode is 20 psi with the maximum pressure of 30 psi. When used for both proportional and smoke applications, a separate air signal should be provided to override normal HVAC operations and enact safety damper functions.

Note: The D-3062 is not able to be configured for frame mounting in normally open damper applications.

Operation

Air pressure from a pneumatic controller is applied to the diaphragm of the actuator, which moves the piston against the forces of the internal spring and the load. The external load force shifts the operating range from the nominal spring range. The piston will move to a position where the applied force and the spring plus external forces are in equilibrium.
