Description
The Siemens 333-043-03 9″ long 1/2″ diameter steel shaft extension rod is frequently used in HVAC systems. This is needed to enhance the functionality of damper actuators to achieve accurate airflow control in ductwork. The actuator’s leverage is increased and so is operational smoothness and responsivity through the use of a shaft extension rod to the damper. This increased control has a positive impact on better indoor comfort, energy efficiency and system performance. The steel rod it is made of is tough and will operate well under harshness our HVAC needs. Its build and makes it easy to install and maintain.
