Description
Siemens 332-2973 Damper Actuator Pneumatic is a high quality actuator, used to regulate dampers precisely in HVAC systems. Its universal mounting mechanism makes this actuator easy to fit into a wide range of configurations. The actuator is small but mighty at 6.93″ x 9.33″ x 20.83″ With a 4″ stroke it has the range of motion to efficiently control airflow via dampers. The actuator positions the damper consistently and reliably based on pneumatic indications within a spring range of 8 to 13 PSI. For this reason it is for commercial HVAC systems exact air distribution control is required. The universal mounting style provides more installation freedom, making better occupant comfort and reliable performance.
