Make-Up Air Units (MUA) are specialized ventilation systems designed to “make up” the air that is exhausted from commercial and industrial facilities. When buildings expel air due to equipment like exhaust fans or hoods, it can create negative pressure inside the facility. An MUA system compensates for this by supplying fresh, conditioned air back into the building, ensuring a balanced air pressure and improving indoor air quality. Additionally, these units can be equipped with heating or cooling coils to condition the incoming air, ensuring it is at a desired temperature when introduced into the building. Regular maintenance of MUA systems is essential to ensure efficient operation and a healthy indoor environment.
