What is the minimum horizontal distance an exhaust opening should be from a mechanical air intake opening?

The minimum horizontal distance of 10 feet between an exhaust opening and a mechanical air intake opening is crucial for maintaining safe and efficient ventilation within a building. This distance helps to prevent contaminants, fumes, or exhaust gases from being inadvertently drawn back into the building through the air intake system. By adhering to this standard, the risk of poor indoor air quality and potential health hazards is significantly reduced.

Moreover, this distance is typically specified in building codes and standards, reflecting industry best practices aimed at ensuring that ventilation systems operate effectively. Maintaining this separation promotes optimal airflow and ensures that fresh, unpolluted air is supplied to the mechanical systems of the building. This distance is particularly vital in settings where various sources of emissions may be present, contributing to a safer and healthier environment.
