What is the required distance for environmental exhaust from mechanical intake?

The required distance for environmental exhaust from mechanical intake is 10 feet. This specific distance helps to ensure that exhaust fumes or contaminants from outdoor sources do not adversely affect the air quality being drawn into mechanical ventilation systems, such as those found in air conditioning and refrigeration units. Keeping this separation minimizes the risk of harmful pollutants entering the intake, which can compromise the efficiency and safety of the HVAC system, as well as indoor air quality for building occupants. This guideline is essential in various building codes and HVAC design standards to promote safe and effective environmental controls.
