What Is Makeup Air?

Makeup air is typically outdoor air that is supplied into a kitchen hood or other occupied space to replace air that is removed by exhaust fans out of the kitchen hood or space. It also helps to maintain balanced airflow inside the building structure.

Restaurant hoods and other commercial kitchen ventilation systems require makeup air to replace or ‘makeup’ the air that is exhausted by powerful exhaust fans.

In order to accommodate this need, these large hoods require dedicated makeup air to supply a sufficient amount of fresh outdoor air. Serious issues related to negative pressure can occur if a prolonged imbalance between the exhaust to supply air ratio exists.


Who Needs Makeup Air Fan Repair Service?

Makeup air is commonly required to satisfy code requirements for restaurant kitchen hoods that exhaust larger volumes of air, and municipalities are increasingly requiring it for new residential construction.
