Where should the inlet of an exhaust system be located?

The location of an exhaust system inlet is critical for effective ventilation and maintaining air quality. Placing the inlet in the area of heaviest concentration of contaminants ensures that the exhaust system can effectively capture and remove harmful gases, chemicals, or particles from the environment. This strategic positioning minimizes the chance of contaminants accumulating in spaces where people might be, thereby improving overall safety and comfort.

Additionally, this approach aligns with the principles of good ventilation practices, which prioritize the removal of pollutants at their source. It ensures that the air being exhausted is coming from areas that need it most, allowing for more efficient operation of the exhaust system.

Choosing an unoccupied area, at the roof level, or near windows may not address the need for efficient contaminant removal and could result in inadequate ventilation, leading to possible health hazards. For optimal performance and safety, it's vital to identify and utilize the most contaminated areas for the placement of exhaust inlets.
