Makeup Air Units

Why Makeup Air Units Matter in Commercial Kitchens

In any busy commercial kitchen, good airflow is essential. Without it, you're left with hot, smoky conditions and overworked equipment. That’s where makeup air hoods come in.

These systems work with your exhaust hoods to keep air pressure balanced. As the hood pulls air out of the kitchen, a makeup air unit brings fresh air back in—helping maintain comfort, meet safety codes, and support energy efficiency.

At HoodMart, our makeup air hoods packages are engineered to deliver consistent airflow, reduce fire risk, and keep your kitchen operating smoothly.

What is a Makeup Air Unit?

A makeup air unit is a key part of your kitchen’s ventilation setup. It brings in fresh, filtered air to replace the air being pulled out by the exhaust hood.

Without it, you risk creating negative air pressure - which can cause smoke and heat to linger, make doors slam, and pull in air from unwanted places like bathrooms or storage areas.

Here’s why balanced airflow matters:

  • Better hood performance: Exhaust systems work more efficiently when there’s a steady supply of incoming air.
  • Code compliance: Proper ventilation helps meet standards like NFPA 96 and UL listings, which are required for fire safety.
  • Improved comfort: Balanced airflow makes it easier to regulate kitchen temperature and humidity, which keeps staff more comfortable.
