CAPTIVE-AIRE Architectural Square Top Gravity Vent

The Architectural Square Top Non-Motorized Gravity Vent functions as a simple, economical makeup air intake. It is best suited for spaces where fresh air replacement can occur passively without a powered fan. Ideal for small or retrofit projects where budget is a primary concern and a reliable air inlet is required. It supports up to 2230 CFM against static resistance, making it appropriate for moderate exhaust loads in bakeries, locker rooms, offices, and light commercial kitchens. A limitation is that it relies on ambient pressure differences rather than active ventilation, which may be less controllable than powered options.
HOODMART 7′ Kitchen Hood System with Economy Makeup Air

This 7-foot kitchen hood system combines exhaust and makeup air components into a compact, heavy-duty package. It includes an exhaust fan (1750 CFM) and a low-profile makeup air supply fan (1400 CFM), all housed in a 304 stainless steel structure with welded joints for durability. Best for restaurants needing a complete hood solution with integrated makeup air to maintain a comfortable work environment. Better for medium to large kitchens with grease and heat control needs. A potential limitation is the fixed configuration; custom ducting may be required for non-standard layouts.
CAPTIVE-AIRE Commercial Kitchen MUA and Supply Fan Metal Mesh Filters (20″ x 25″ x 2″)

These aluminum-framed metal mesh filters capture dirt and dust from the air stream for commercial kitchen supply fans, heaters, and makeup air units. The two-pack with 20” x 25” x 2” dimensions offers a robust filtration solution for medium-to-large MUA systems. Best for facilities needing reliable filtration to protect downstream equipment and maintain air quality. Choose this if you prioritize easy replacement and corrosion resistance; note that performance depends on appropriate filter size matches to your unit.
CAPTIVE-AIRE Commercial Kitchen MUA and Supply Fan Filters (20″ x 25″ x 1″)

This two-pack of 20″ x 25″ x 1″ metal mesh filters provides a slim option for tight installations while offering corrosion resistance and efficient particle capture. Best for retrofit projects or compact MUA intakes where space is limited. Avoid this size if your system requires deeper filter media for higher dust loads; confirm compatibility with your make-up air unit before purchase.
CAPTIVE-AIRE MUA Filters 16″ x 20″ x 2″ (Two Pack)

A two-pack of 16” x 20” x 2” metal mesh filters designed for smaller MUA intakes or supply fan applications. Best for compact kitchens or spaces with limited mounting room where a tighter filtration footprint is needed. Consider upgrading to the larger sizes if your system handles higher air volumes or has a larger intake to optimize filtration surface area.
HOODMART 9’ Restaurant Hood with PSP Makeup Air

This 9-foot restaurant hood system integrates makeup air with a perforated supply plenum (PSP) and features 18 Gauge 430 stainless steel construction. UL-listed to ANSI / UL 710 and NSF, UL, NFPA, and ETL approvals, making it suitable for established commercial kitchens seeking a compliant, robust makeup air solution. Best for larger kitchens or facilities that require a high-volume, code-compliant air balance. A limitation can be higher initial cost and longer installation time for larger configurations.
HOODMART 4000 CFM Fresh Air Supply Fan

This 4000 CFM fresh air supply fan is housed in galvanised steel with weatherproof cabineting designed for outdoor roof mounting. Its forward-curved belt drive blowers operate quietly at low speeds, providing substantial makeup air capacity for high-demand kitchens. Best for large facilities or outdoor installations where a strong, weather-resistant air supply is required. A consideration is that high airflow systems may need additional ductwork and controls to optimize performance.
Buying Guide
What should you prioritize when selecting a kitchen makeup air unit?
- Airflow requirements: Match CFM to exhaust load and kitchen size. Larger kitchens need higher CFM or combined exhaust/makeup air strategies.
- System type: Decide between gravity vents, complete hood systems with makeup air, or high-capacity make-up air fans based on installation constraints and control needs.
- Filtration: Ensure filters are compatible with your air path and can be easily replaced to maintain air quality and equipment longevity.
- Materials and durability: Stainless steel and corrosion-resistant components are essential in grease-rich kitchen environments.
- Code compliance: Look for UL, NSF, NFPA, or ETL listings where required for commercial kitchens.
- Installation footprint: Consider space constraints—compact builds work well in retrofits, while full hood systems suit new builds or larger remodels.
- Maintenance access: Favor designs with accessible filters and serviceable components to reduce downtime.
FAQ
- What is makeup air in a kitchen?
Answer: Makeup air is outdoor air introduced into a space to replace air exhausted by kitchen hoods, ensuring proper negative or positive pressure balance and occupant comfort. - Do I need a powered makeup air system or a gravity vent?
Answer: For high-heat, high-exhaust kitchens, powered makeup air often provides better control. Gravity vents are economical but rely on pressure differences and may offer less control. - Can I mix different makeup air components?
Answer: Yes, many facilities combine hoods, fans, and filters. Ensure compatibility of airflow, ducting, and filtration with your existing system. - What maintenance is required for MUA filters?
Answer: Regular inspection and replacement per manufacturer guidelines keep airflow up and protect equipment from dust buildup. - Is UL or NSF listing important for kitchen equipment?
Answer: Yes, listings help ensure safety, compatibility with code requirements, and reliable performance in commercial kitchens. - Which option is best for retrofits?
Answer: Compact hood systems or gravity vent-based approaches are often easier to retrofit into existing kitchens with minimal structural changes.
