Dedicated Outside Air System (Doas)
A dedicated outside air system (Doas) is a type of mechanical ventilation system that supplies conditioned outside air to a space. Doas systems are typically used in commercial and institutional buildings such as office buildings, schools, and hospitals. The main advantage of a Doas system is that it can provide fresh air to a space without the need for opening windows or doors. This helps to keep the space comfortable and reduces the risk of airborne contaminants entering the space.
