To reduce noise and vibration in critical areas, what should be used between the duct and the fan?

Using a flex connector between the duct and the fan is essential for minimizing noise and vibration in critical areas. Flex connectors are made of flexible materials that can absorb the vibrations generated by the fan, preventing them from transmitting through the ductwork. This not only helps in reducing noise levels but also protects the duct system from structural stress and potential damage that could result from the vibrations.

Flex connectors play a crucial role in maintaining the integrity of the HVAC system by allowing for some movement and expansion, which is particularly important in systems where airflow might change or where the ducts are subjected to temperature fluctuations. By incorporating a flex connector, the overall comfort and performance of the system can be significantly enhanced.
