FICBXRA Direct Drive Upblast Exhaust Fan — 5000 CFM
Best for fast, grease-aware kitchens requiring robust exhaust with low maintenance. This 1.5 HP, 110V single-phase fan delivers 5000 CFM and uses a direct-drive centrifugal upblast design. The unit is lightweight, corrosion-resistant aluminum and suitable for roof or wall mounting. Intended for restaurant grease-rated exhaust and general ventilation, it provides strong performance with minimal moving parts.
Best for: restaurant kitchens and high-traffic prep areas where reliable exhaust is crucial. Limitation: 110V single phase may require a dedicated circuit and appropriate wiring on site.
FICBXRA Direct Drive Upblast Exhaust Fan — 5000 CFM (ETL Listed)
This listing mirrors the 5000 CFM capacity with identical construction and ETL listing, reinforcing suitability for kitchens seeking code-compliant, grease-rated ventilation. Best for operators who want consistent performance with tested electrical safety standards. The aluminum housing remains corrosion-resistant and easy to maintain. Caution: ensure electrical supply aligns with single-phase 110V requirements.
CAPTIVE-AIRE 28″ Direct Drive Upblast Exhaust Fan — 3000 CFM
Best for large canopy installations where precise control and airflow management are needed. The CAPTIVE-AIRE unit runs at 1183 RPM and operates at 208V three-phase, delivering 3000 CFM with a 28″ wheel. It includes adjustable speed control and a disconnect. Suitable for professional kitchens and other commercial facilities requiring reliable, high-volume exhaust. Limitation: three-phase power is required.
HYITCL 5000 CFM Upblast Direct Drive
Best for industrial and commercial kitchen ventilation needing heavy airflow with corrosion-resistant aluminum construction. The HYITCL unit offers 5,000 CFM, 1.5 HP, and 110V single-phase operation. It is designed for roof or wall mounting and targets grease-rated exhaust. Caution: confirm local electrical compatibility and mounting structure for weight and vibration considerations.
HYITCL 3500 CFM Direct Drive Upblast — 1 HP
Best for smaller kitchens or spaces with moderate ventilation needs. This unit provides 3500 CFM with a 1 HP motor at 110V/220V single-phase. It uses lightweight aluminum for corrosion resistance and is suitable for rooftop or wall mounting. Better for spaces where lower airflow suffices and where energy use matters.
FICBXRA 6300 CFM 2 HP Upblast Exhaust
Best for large facilities and heavy-duty kitchen environments needing high-volume exhaust. This 2 HP, 208-230V unit delivers 6300 CFM with a robust aluminum housing for corrosion resistance. It is designed for roof or wall mounting and is ideal where maximum airflow is required. Limitation: higher power and weight may demand reinforced mounting and wiring considerations.
FICBXRA 800 CFM Downblast Roof Exhaust Fan
Best for general ventilation in food trucks or smaller facilities where grease is not a primary concern. The downblast design focuses on general air movement, with 0.18 HP and 800 CFM at 110V single-phase. It’s lightweight and easy to install, but not intended for grease-laden exhaust. Choose this if you need portable or compact coverage rather than heavy grease control.
FICBXRA 5000 CFM Downblast Roof Exhaust
Best for mid-to-large spaces requiring downblast ventilation with significant airflow. The unit provides 5,000 CFM at 1.5 HP and 110V/120V single-phase. It uses a corrosion-resistant aluminum housing for durable operation. Limitation: not designed for exhausting grease, so use in non-grease zones or with separate grease-rated systems.
Buying Guide
- Airflow requirements: Match CFM to the room or hood size. Higher CFM is better for larger kitchens or faster air changes, but consider noise and energy use.
- Voltage and phase: Verify available electrical service. 110V single-phase is common, but larger installations may require 208-230V three-phase.
- Grease rating: For restaurant kitchens, choose grease-rated upblast models. For general spaces, downblast or non-grease units may suffice.
- Mounting location: Roof vs. wall mounting affects installation, weight support, and ducting. Ceiling clearance and weather exposure matter for outdoor units.
- Material and durability: Aluminum housings offer corrosion resistance and lighter weight, beneficial in rooftop environments.
- Serviceability and electrical safety: Look for ETL or similar listings for compliance and easier maintenance planning.
FAQ
- What is a direct drive centrifugal fan? It uses a direct-drive motor to spin the impeller, delivering high airflow with fewer moving parts and typically lower maintenance.
- What does “upblast” mean? An upblast exhaust directs air upward, reducing upward duct resistance and facilitating duct routing above the unit.
- When should I choose a downblast fan? Downblast fans push air downward and are often used where ducting is below the unit or for non-grease spaces.
- Are grease-rated fans necessary for kitchens? Yes, grease-rated units are designed to handle kitchen exhaust without premature corrosion or failure.
- How do I determine the right CFM? Consider hood size, room volume, desired air changes per hour, and local code requirements.
- Can I mix single-phase and three-phase fans in one system? Yes, but ensure electrical supply, controllers, and safety devices are appropriately matched to each unit.
