What Are Make-Up Air Units?
A make-up air unit (MAU) is a specialized ventilation system that brings in 100% fresh outdoor air to replace what’s removed by exhaust fans. By introducing clean, tempered air, MAUs improve indoor air quality, balance humidity, and maintain comfortable conditions—all while reducing stress on your existing HVAC system.
Key Benefits of Make-Up Air Units
- Stable Temperatures & Humidity: MAUs deliver fresh, heated air—ideal for colder climates or when make-up air needs to be heated—ensuring consistent comfort in any environment.
- Enhanced Air Quality: By constantly replenishing indoor air with filtered outside air, MAUs help minimize pollutants, odors, and contaminants.
- Energy Efficiency: Make-up air unit rentals provide cost-effective, fuel-efficient heating options that reduce energy consumption and improve system longevity.
Applications
- Construction Sites: Control dust and maintain healthy air quality during building projects.
- Industrial Facilities: Ensure proper ventilation, reduce pollutant buildup, and keep workers comfortable.
- Events & Temporary Projects: Create a pleasant, well-ventilated atmosphere for guests and staff.
Make-Up Air Units vs. Recirculation Units
Unlike recirculation units that reuse indoor air, make-up air units constantly introduce fresh air. This prevents pollutant accumulation, stabilizes temperature and humidity, and supports a healthier indoor environment.
