Johnson Controls D-4073 Pneumatic Piston Damper Actuator
The D-4073 Pneumatic Actuator is a multipurpose positioning device used to accurately position small dampers primarily on unit ventilator, Variable Air Volume (VAV), terminal units, and small ventilating dampers in response to output signals of a pneumatic controller or electro-pneumatic transducer.
The actuator is also recommended for use on other air flow control dampers, in interior locations, up to a maximum area of 6.75 square feet for proportional volume control and 11.7 square feet for two position actuation provided that the torque requirements are compatible with the specific application. The D-4073 is a direct replacement for existing D-3073 actuators and a functional replacement for former D-251 actuators.
• 2-way swivel connection ensures nonbinding movement and full power delivery
• glass reinforced polymer housing which is lightweight, corrosion and chemical resistant
• telescoping linkage for fast and flexible installation
