What exactly is a make up air unit for a kitchen?
When you add a make up air unit for your kitchen, it adds replacement air for what’s being drawn out of the kitchen by your exhaust hoods.
What is make up air? Simply stated, a make up air unit pulls air in to your space from outdoors and conditions it to the indoor temperature, to replace air that’s pulled out by your kitchen exhaust equipment. Without it, you get back drafting, poor temperature control, negative air pressure and air quality problems.
Let’s explore the reasons why a make up air unit is so essential for restaurant kitchens.
Why is Make Up Air Important for Restaurants?
Depending on the type of cooking you are doing, you might even have more than one exhaust system in your kitchen: one for heat & grease generating cooking appliances (like fryers, grills, and cooktops) and another for steam-generating appliances (such as dishwashing equipment and baking ovens).
Restaurant kitchen exhaust systems are often very powerful, removing thousands of cubic feet of air per minute. When air is removed from your kitchen, it needs to be replaced with fresh air. Without that replacement air, you wind up with all sorts of unpleasant and even dangerous conditions, which we’ll get to in a minute. The problem is compounded in newer buildings constructed to be air-tight, which prevents the natural flow of outside air into the space.
