FICBXRA Upblast Exhaust Fan, 5000 CFM
Best for high-flow kitchen exhaust with grease-rated requirements. This direct-drive centrifugal upblast model operates at 1.5 HP with a 110V single-phase motor and delivers 5000 CFM. It is designed for roof or wall mounting and uses corrosion-resistant aluminum components. Ideal for large restaurant canopies needing strong exhaust without a belt or pulley maintenance burden. Limitation: single-phase operation may require specific electrical setup and may exhibit limited dynamic balancing at extreme loads.
FICBXRA Direct Drive Upblast, 5000 CFM (ETL Listed)
Best for facilities prioritizing ETL-listed equipment with grease-rated performance. This unit mirrors the 5000 CFM capacity and 1.5 HP, 110V single-phase configuration. It is suitable for rooftop or wall installation and uses lightweight aluminum to resist corrosion. Caution: ensure proper duct sizing and support structure to handle the weight and wind loading at height.
CAPTIVE-AIRE Canopy Hood Exhaust Fan, 3000 CFM
Best for mid-range kitchen exhaust with three-phase power. The 28″ fan base and 3000 CFM rating are paired with a three-phase 208V motor and speed control. It includes a disconnect switch and a robust wheel, making it a strong choice for kitchens with standardized three-phase electrical infrastructure. Limitation: higher upfront electrical requirements for three-phase wiring.
HYITCL Roof Ventilator, 5000 CFM
Best for aluminum, corrosion-resistant construction with grease-rated performance. The 1.5 HP, 110V single-phase model delivers 5000 CFM for large kitchen spaces. It is designed for roof mounting and emphasizes lightweight design. Caution: verify local wind load requirements and secure mounting hardware for high-rise installations.
HYITCL Hood, 3500 CFM, 1HP
Best for smaller or budget-conscious kitchens needing grease-rated exhaust with straightforward installation. Features 1 HP, 110/220V single-phase operation and aluminum construction. It is lighter than larger models, which may simplify mounting but limits maximum CFM compared to higher-capacity units. Avoid if you require very high airflow in a compact space.
FICBXRA 6300 CFM, 2HP Upblast
Best for high-demand kitchens needing maximum exhaust capacity. The 6300 CFM rating at 2 HP, 208-230V, offers robust performance for large or multiple hood configurations. It is mounted on roofs or walls with a lightweight, corrosion-resistant aluminum build. Limitation: higher voltage requirement may necessitate specialized electrical work and potentially larger installation clearances.
Buying Guide
Direct drive centrifugal fans move air efficiently with fewer moving parts than belt-driven models, reducing maintenance needs. Key considerations include:
- Airflow needs (CFM): Match the unit to kitchen size and hood design to avoid under- or over-ventilating.
- Voltage and phase: Single-phase systems suit smaller facilities; three-phase systems can offer smoother control for larger installations.
- Grease-rating: Choose grease-rated upblast units for kitchen exhaust to minimize grease buildup in the fan housing.
- Mounting location: Roof vs. wall-mounted configurations affect mounting hardware, structural support, and duct runs.
- Material and finish: Aluminum construction reduces weight and corrosion in greasy environments.
- Electrical safety: Ensure proper disconnects, wiring, and clearance per local codes.
FAQ
- What is direct-drive in centrifugal fans?
Direct-drive means the motor connects directly to the fan wheel, eliminating belts and pulleys for lower maintenance and efficient power transfer. - What airflow is appropriate for a small kitchen?
Small kitchens typically require 3000-5000 CFM depending on hood size and cooking load; consult hood manufacturer guidelines for exact numbers. - Do grease-rated fans require special installation?
Yes, grease-rated units are designed to resist grease buildup; ensure proper ducting, grease containment, and regular cleaning schedules. - Is three-phase power better than single-phase for these fans?
Three-phase systems can offer smoother operation and may be preferable for high-CFM commercial installations; verify facility electrical capabilities. - Can I mount these fans on a rooftop or wall?
Most models support both roof and wall mounting; confirm each unit’s mounting details in the product spec and ensure structural compatibility. - What maintenance do these fans require?
Typical needs include annual lubrication of bearings (if applicable), periodic belt checks (for belt-driven variants only), and regular cleaning to remove grease buildup.
