Siemens 332-2961 Damper Actuator Pneumatic No.4 8-13 PSI W/Pivot Post

The Siemens 332-2961 Damper Actuator Pneumatic No.4 is a strong and steady part for the control of air temperatures in HVAC systems. The pneumatic pressure powers the airflow in this actuator, within a spring range of 8-13PSI, applications which want consistent and adjustable force. Flexible installation is enabled by pivot post mounting which enables damper system compatibility. The system offers an ample stroke of 4" which delivers enough movement for the ESU's to operate effectively on air to help improve system performance and efficiency. This is commonly an actuator used aboard commercial and industrial HVAC systems where it is used to control fan airflow and maintain appropriate environment conditions.
