Do I need a make up air system?

Having make-up air always is a good idea when using a hood to exhaust grease/smoke-laden air. You need make-up air per the IMC, if exhausting more than 400 cfm. Using a rooftop unit to compensate for the exhausted air is common when exhausting less than 800 cfm.

What is the difference between makeup air and outside air?

Why is makeup air important?

A make-up air unit does the job of bringing in outside air to the building, not the circulated air that most ventilation systems use.

Why is makeup air required?

Aside from the code requirements, make-up air also plays a pivotal role in the function of an exhaust system. In the absence of a make-up air solution, the exhaust fan's continuous removal of air from the space creates negative pressure in the building.
