Best Practices for Installing Makeup Air Systems in Residential Kitchens

A unitary makeup air system is a comprehensive solution that requires only one exterior penetration. All components, including the fan, pleated filter and controller are integrated into a single unit. Optional accessories include electrical duct heaters and silencers. This design simplifies installation and minimizes exterior modifications.

Modular systems consist of individual components - an inlet air hood, filter box, makeup air fan, and silencer. This type offers flexibility in configuration and installation, allowing customization to meet specific designs. Accessories like electrical duct heaters can be added to enhance performance and comfort.

• Consider Airflow Needs: Accurately calculate the required airflow based on the kitchen size and exhaust capacity to ensure efficient ventilation and balanced air distribution (U.S. Department of Energy, 2022).  

• Match Exhaust Capacity: Ensure the makeup air system is properly sized to match the capacity of the kitchen exhaust system. Balanced air pressure is critical to prevent negative pressure within the building envelope (ASHRAE, 2020). 

• Strategic Positioning: Place supply vents for efficient airflow, avoiding direct drafts on occupants. If unavoidable, use larger ductwork to reduce air velocity.

• Proximity to Range Hood: Keep vents at least 8 feet from the range hood for effective air distribution. Many contractors integrate vents into kitchen cabinets for discreet, efficient airflow.

• Easy Access: Install components for easy maintenance, ensuring optimal performance.

• Clear Guidance: Provide simple instructions for filter changes and inspections.

In this installation example, the MUAS was concealed in cabinet that is an architectural feature of the adjacent dining room.

• Heater Accessory: In colder climates, consider integrating a heater accessory with the makeup air system to prevent indoor temperature drops during colder months.

• Silencer Accessory: To minimize noise, install a silencer accessory to ensure a quieter and more comfortable kitchen environment (Energy Star, 2021).

Our unitary system is engineered for flexibility and efficiency, featuring adaptable mounting options and a space-saving design that provides engineers, builders, and contractors with simple, versatile installation solutions. 

• Horizontal and Vertical Mounting: The unitary system is designed for installation in both horizontal and vertical orientations, accommodating various kitchen, attic or mechanical room layouts, for example. 

• Space Efficiency: Flexible mounting options make the system ideal for tight spaces, including small mechanical rooms or compact kitchens, where maximizing space efficiency is crucial. 

• One Exterior Penetration: The system requires a single exterior penetration, simplifying installation and reducing the risk of air leaks or structural compromises. 

Designed for flexibility, our modular system allows engineers, builders, and contractors to customize ventilation configurations to meet specific project needs. Built for both versatility and performance, it seamlessly integrates into a wide range of applications.

• Modular Design: The system’s adaptable structure enables customization for airflow and pressure requirements, ensuring optimal performance.

• Component Selection: With separate components like fans, filter cassettes, duct heaters, and silencers, engineers can mix and match elements for maximum efficiency.

• Customization for Complex Installations: Ideal for multi-zone and community kitchens, the system offers the flexibility needed for intricate setups while maintaining high performance and efficiency.
