In every commercial or restaurant kitchen ventilation system, the same amount of air that is ventilated out must be replaced by fresh air that comes back in. This is accomplished via a make-up air unit. If a proper air balance isn’t maintained, the building pressure can become negative causing problems such as poor exhaust fan performance or grease and smoke spillage from the hood.

A full-service commercial kitchen cannot rely solely on their HVAC system to supply all of the necessary air to maintain balanced kitchen airflow, so a make-up air unit is needed. Typically, 80% of your makeup air will come from a make up air unit, and the other 20% will come from your building’s HVAC system.
