Siemens 331-2929 Damper Actuator Pneumatic No.4 3-7 PSI Pivot Mount

Siemens 331-2929 Damper Actuator Pneumatic No.4 is an all round robust and capable component used to be able to modify damper positions in HVAC systems. The pneumatic actuator operates at a range between 3-7PSI and is suited for use in applications where precisely controlled airflow is needed. A simple installation and positioning design along with 4" stroke provides movement range for efficient damper operation. Typically used in HVAC systems to control open/close of dampers and air flow through duct work, this pneumatic actuator is relatively large and cavernous. The places of door's damper to change correctly will help in maintaining required temperature and airflow levels, for that intends result in general upgrade in the performance of the HVAC system.
