FICBXRA Roof Centrifugal Makeup Air Fan 16”
The FICBXRA 16” rooftop makeup air fan provides a robust, weather-resistant solution for commercial kitchens needing reliable air balance. Its galvanized steel housing protects against rust, and the heavy-duty insulated cabinet supports roof or sidewall mounting. A removable aluminum mesh filter offers straightforward daily cleaning and a large surface area for efficient filtration. With a 1 HP, 110V single-phase motor delivering up to 2875 CFM and 1720 RPM, this unit is ETL certified for safety and reliability, ensuring consistent makeup air delivery to offset exhaust. This option is ideal for larger kitchen hoods where strong airflow and durable construction are priorities.
HOODMART 5′ Kitchen Hood System
This all-in-one kitchen hood system from HOODMART combines heat, smoke, and grease management with a dedicated makeup air strategy. The 48” x 5’ hood covers a broad cooking footprint. It includes an exhaust fan rated at 1250 CFM (115V) and a low-profile supply fan at 1000 CFM (230V), plus stainless steel internal components and perforated plenums for even air distribution. The unit comes with stainless steel grease baffles, grease cups, lighting, speed control, and mounting hardware. Built with 18-gauge stainless steel, its welded joints provide reliable construction for commercial kitchens seeking a turnkey MAU solution integrated with the hood system. This option is suited for mid-sized kitchens needing an efficient, compact, and maintenance-friendly setup.
Broan MD8TU 8″ Universal Make-Up Air Damper
The Broan-NuTone MD8TU damper provides a compact, universal solution for incorporating forced or passive makeup air into kitchen ventilation. While exact dimensions are not listed, its 8-inch size makes it compatible with many hood plenum configurations and ducting layouts. This damper is a critical component for controlling makeup air flow in systems where precise, regulated air balance is required. In installations that favor energy efficiency, the damper can be integrated with controls to modulate air intake in response to kitchen exhaust demands, reducing unnecessary heat loss or gain.
FICBXRA Roof Centrifugal Makeup Air Fan 14”
The 14” version from FICBXRA delivers a strong makeup air solution with a 2450 CFM capacity and a 3/4 HP direct drive motor, making it a good fit for mid-size kitchens and installations with moderate exhaust demands. It shares the same rugged construction as larger models: galvanized housing for weather resistance, a removable unit filter for easy maintenance, and an ETL certification for safety and reliability. The unit’s intake hood and filter assembly help ensure clean, filtered air delivery to the space, supporting stable indoor temperatures and occupant comfort during peak cooking periods.
CAPTIVE-AIRE EMUA10 Economy Make Up Air Unit
The EMUA10 is a non-motorized gravity vent designed as an economical makeup air solution. It’s suitable for situations where fresh air is needed to replace exhaust air but where added energy penalties from a powered fan are undesirable. Applications include commercial kitchens, offices, bakeries, laundries, factories, and warehouses. The EMUA10 offers up to 750 CFM against static resistance, providing a straightforward path to compliant makeup air without electrical components. It’s a practical option for retrofits or spaces with minimal exhaust pressure fluctuations.
Buying Guide: Key Considerations For Selecting a Kitchen MAU
- Airflow needs: Assess exhaust volume from the hood against the available makeup air. Larger kitchens or higher-heat cooking areas require higher CFM makeup air capacity for balance and comfort.
- Motor and energy use: Powered MAUs deliver strong airflow but consume energy. Consider efficiency, motor type (direct drive vs. belt, single-phase), and potential for variable-speed controls to optimize operation during peak and off-peak hours.
- Installation location: Roof-mounted units protect indoor spaces but require structural support, weatherproofing, and proper drainage. Wall or hood-integrated solutions may simplify ducting.
- Maintenance: Removable filters, accessible housings, and ease of cleaning reduce downtime. ETL or UL listings indicate compliance with safety standards.
- Control strategy: Damper-integrated or smart controls can modulate makeup air in response to hood exhaust, improving energy efficiency and comfort.
- Economics vs. performance: Non-motorized gravity vents offer low cost and minimal energy use but lack active airflow control. For high-demand kitchens, powered MAUs deliver reliable performance even in peak times.
- Code compliance: Verify that the MAU design meets local mechanical and energy codes, including requirements for makeup air in commercial kitchens and restaurants.
- Compatibility: Ensure damper, plenum, and hood configurations align with existing ductwork and space constraints to prevent air leaks or backdrafts.
In selecting a make-up air unit for a kitchen hood, priorities typically balance airflow capacity, energy efficiency, and installation practicality. For large, high-traffic kitchens, rooftop or integrated systems with high CFM and robust filtration offer reliable performance. For retrofit projects or cost-sensitive applications, non-motorized solutions provide a straightforward path to compliant makeup air while minimizing ongoing energy costs.
