Economy Make Up Air Unit EMUA10 — Non-Motorized Gravity Vent
The EMUA10 is a non-motorized gravity vent designed as an economical option when fresh air intake or pressure relief is needed. It can be used anywhere fresh air is required to replace exhaust air, including commercial kitchens, offices, bakeries, laundries, factories, warehouses, and locker rooms. It provides up to 750 CFM against static resistance, offering a straightforward, low-maintenance solution for building pressurization and vent balance.
FICBXRA Roof Centrifugal Supply Air Fan — 16” Blower, 2875 CFM
This rooftop makeup air unit features a galvanized steel housing for rust-free, weather-resistant durability and a heavy-duty insulated cabinet suitable for roof or sidewall mounting. It includes a removable aluminum mesh filter for easy maintenance and efficient filtration. The unit delivers up to 2875 CFM with a 1 HP 110V motor and ETL safety certification, supporting robust commercial kitchen or facility air balance needs.
Commercial Kitchen Make Up Air and Filters (Two Pack)
These aluminum-frame filters capture dirt and dust from the air stream in kitchen supply fans, heaters, and make-up air units. The two-pack measures 20” x 25” x 2” each, featuring rigid, heavy-duty construction and corrosion resistance. They are designed to extend filter life and minimize downtime in high-heat, grease-prone kitchen exhaust environments.
EMUA12 Economy Make Up Air Unit — Non-Motorized Gravity Vent
The EMUA12 model provides another non-motorized gravity vent option with 1000 CFM against static resistance. It is suitable for situations requiring a cost-effective means to bring in fresh air or relieve pressure. Ideal for commercial kitchens, offices, bakeries, laundries, and larger spaces needing balanced air exchange without powered makeup air systems.
EMUA18 Economy Make Up Air Unit — Non-Motorized Gravity Vent
The EMUA18 offers a higher capacity at 2400 CFM against static resistance, maintaining fresh air intake or pressure relief for larger commercial kitchens and facilities. Its non-motorized gravity vent design emphasizes low maintenance and reliability, suitable for installations where powered makeup air is not required or desired.
FICBXRA Roof Air Supply Fan Direct Drive Downblast — 2400 CFM
Direct-drive axial makeup air unit designed for rooftop installations, featuring a spun aluminum hood and skirt for weather protection. It includes a built-in protective screen to guard discharge and ensure safe, obstruction-free operation. This unit supports robust air delivery with a compact, maintenance-friendly design.

This 48-inch by 5-foot kitchen hood system includes a 1250 CFM exhaust fan, a 1000 CFM low-profile supply fan, and a complete set of components for installation, including stainless steel components and grease filtration. It is designed to exhaust heat, smoke, and grease while providing ample makeup air, balancing kitchen ventilation in a single integrated package.
Buying Guide: Key Purchase Considerations
- Airflow requirements: Match CFM and static pressure ratings to kitchen equipment and exhaust volume. Higher CFM helps with bigger kitchens but may require larger ductwork and noise considerations.
- Motorized versus non-motorized: Non-motorized gravity vents are low-maintenance and economical for passive air exchange, while motorized or direct-drive units supply controlled air and are better for precise balancing in active exhaust environments.
- Installation type: Roof-mounted, sidewall, or hood-integrated units influence duct routing, weather protection, and maintenance access. Choose a design that minimizes energy loss and simplifies service.
- Filtration: Upstream filters protect downstream equipment and improve air quality. Consider filter life, construction, and ease of cleaning or replacement.
- Durability and materials: Stainless steel and galvanized housings withstand grease, heat, and humidity typical of commercial kitchens.
- Noise and vibration: Acoustic considerations matter for staff comfort and compliance with local noise ordinances. Look for insulated cabinets and low-vibration mounts.
- Maintenance and access: Removable filters, accessible housings, and clear service instructions reduce downtime and extend unit life.
- Compliance and safety: Ensure units are ETL-listed or equivalently certified and compatible with existing electrical and building codes.
- Total cost of ownership: Factor initial cost, energy use, maintenance frequency, and filter or parts replacement into long-term planning.
