Description
The Johnson Controls D-3244-3 is a heavy-duty pneumatic damper actuator engineered for precise damper positioning in commercial HVAC and building automation systems. Delivered as a complete, ready-to-install assembly, it features swivel mounting hardware along with a bracket, clevis, and crankarm — eliminating the need for separate linkage components and reducing installation time in the field.
The unit ships with the D-9502-5 positioner included, providing accurate, repeatable damper control across the full stroke range. With an 8–13 PSI spring range, the actuator delivers reliable spring-return fail-safe operation, ensuring dampers move to their safe position upon loss of control air pressure.
