Spring - Small 100mm (eye at each end)

In HVAC systems, tension springs (also called extension springs) are primarily used to maintain tension on components, ensuring proper airflow and position by providing a consistent pulling force to bring parts back together when they try to separate, effectively controlling movement and maintaining the desired position within the system ; they essentially store and release energy to facilitate smooth operation of various HVAC mechanisms.
Key points about tension springs in HVAC:
Function:

They resist stretching when pulled, absorbing and storing energy to create a return force when needed.

Application examples:

- Holding damper blades in place
- Maintaining tension on belts or pulleys
- Securing components within a unit that might otherwise move due to vibration

Benefits:

- Reliable and consistent force application
- Help maintain proper airflow
- Can contribute to improved energy efficiency
