Where should all connections to a mechanical vent be located?

The connections to a mechanical vent should be located on the inlet side to ensure proper airflow and maintain optimal system performance. Placing connections on the inlet side allows the air to flow smoothly into the system without disrupting the ventilation process, which can happen if connections are made on the outlet or in other areas. This configuration helps to prevent issues such as back pressure, which could impede the function of the vent or reduce the efficiency of the overall system.

Maintaining connections on the inlet side also helps in reducing the risk of contaminants entering the air stream. When connections are strategically placed in this manner, it facilitates easier maintenance and inspection of the system, promoting better air quality and efficiency in operation. Proper placement of connections is crucial for both residential and commercial systems, ensuring they meet the necessary building codes and standards associated with HVAC systems.
