Johnson Controls D-4073-7 Pneumatic Piston Damper Actuator with Auxiliary Mounting Bracket - 3 to 7 psig Range for HVAC Systems | Perfect for Commercial Building Airflow Control

Product Description

The D-4073 Pneumatic Actuator is a multipurpose positioning device used to accurately position small dampers primarily on unit ventilators, VAVs, 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 airflow control dampers, in interior locations, up to a maximum area of 6.75 sq. ft. for proportional volume control and 11.7 sq. ft. 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.
