The importance of having an appropriate and well-maintained ventilation system is sometimes misjudged. In the commercial sector where, for example, large parking garages are in operation, proper air movement is critical to maintaining safe levels of hazardous gases like CO2, which can pose a health risk at concentrations around 5000ppm.

Proper ventilation is also needed to maintain correct pressure inside buildings and prevent backdrafts (outdoor air pulled into the building) and proper air changes per hour, which is the number of times the air inside a given room should be replaced by new air in one hour.

Ventilation systems are sometimes complex, including several components like fans, motors, louvers, dampers, ductwork, and sensors that control the concentration of certain contaminants within the area or section to be mechanically ventilated. That’s why you need a professional on your side to help you to implement, service, and maintain your ventilation systems.
