What is the primary purpose of a flex connector in HVAC systems?

The primary purpose of a flex connector in HVAC systems is to prevent sound transmission. Flex connectors are designed to absorb vibrations and movement caused by equipment operation, which can otherwise transfer sound and vibrations through rigid ductwork. By incorporating flexible materials that can bend and compress, these connectors create a barrier that helps minimize noise levels, especially in systems where noise reduction is a priority for comfort and efficiency.

While there are other roles that components in HVAC systems play, such as providing support or accommodating thermal expansion, the unique function of flex connectors specifically addresses the need to dampen sound energy. This can enhance the overall efficiency of the HVAC system by improving the comfort levels within building spaces without the intrusive effect of mechanical sounds.
