What Is Make-Up Air?

Make-up air is meant to “make up” the air in an interior space that has been removed from the use of process exhaust fans. Make-up air units pull in fresh air from outside of the building to replace the existing air that cannot be recirculated. A make-up air unit is recommended for buildings where environmental conditions warrant a greater need for ventilation. This more efficient ventilation improves the quality of air within the building and protects the health of its occupants.
