Single or combined mechanical exhaust systems must be designed to be what?

Single or combined mechanical exhaust systems must be designed to be independent to ensure they function effectively and safely. An independent system operates separately from other systems, thereby minimizing the risk of cross-contamination between the exhaust and supply air. This independence is crucial in applications where specific ventilation and air quality standards must be maintained, such as in commercial kitchens or industrial settings.

Independent systems can also be essential for meeting code requirements and maintaining proper airflow, helping to mitigate potential hazards and ensuring that exhaust gases and contaminants are removed efficiently from the space. This design consideration fosters better performance and compliance with safety regulations, ultimately enhancing the environment's overall quality and safety.
