Description
The Siemens 331-4825 Pneumatic Damper Actuator increases the flexibility of your HVAC system. It precisely controls air dampers to control effective temperature and airflow modulation. It has a 2 3/4″ stroke and 8–13 PSI spring range. This type of actuator works well in a range of residential and commercial HVAC systems so as to maintain even air distribution and maximize savings in energy. The Siemens 331-4825 controls damper positions and energy consumption exactly for reducing expense and improving indoor air quality. An extended use was realized with low maintenance requirements due to an actuator’s durable construction and reliable pneumatic operation.
