The Benefits of Tempered or Heated Makeup Air Units
Proper airflow is critical in any commercial kitchen—but it’s often overlooked until problems start. From cold drafts to doors that won’t close properly, poor air balance can disrupt your entire operation. Here’s what you need to know, straight from the experts at NAKS, Inc., about makeup air units for restaurants and why tempered air matters.
What Is Makeup Air?
Makeup air refers to the fresh air brought into a building to replace air removed by an exhaust system.
In a commercial kitchen:
- Exhaust hoods remove heat, smoke, and grease-laden vapors
- A makeup air unit replaces that air to maintain balance
Without proper exhaust hood makeup air, kitchens can experience:
- Negative air pressure
- Poor ventilation performance
- Temperature and humidity issues
What Is a Tempered Makeup Air Unit?
A tempered makeup air unit, or heated makeup air unit, warms incoming outdoor air before it enters your space.
This is especially important in colder climates, where:
- Cold outdoor air replaces conditioned indoor air
- Indoor temperatures can drop quickly
- Staff comfort and productivity are impacted
Tempered air systems solve this by:
- Heating incoming air
- Maintaining consistent indoor temperatures
- Supporting overall HVAC performance
Do You Need a Makeup Air Unit for Your Kitchen?
In most cases, yes—especially for commercial kitchens using exhaust hoods. Makeup air units for restaurants are often required by code and play a key role in:
- Maintaining proper air pressure
- Preventing backdrafts near cooking equipment
- Supporting safe and efficient ventilation
- Improving indoor air quality
If your kitchen has an exhaust system, it likely needs a properly sized air makeup unit to operate correctly.
