How to Choose the Right Upblast Exhaust Fan for Your Restaurant

Selecting the right upblast exhaust fan requires careful analysis of airflow needs, duct resistance, grease management, and safety codes. Each factor affects performance and long-term reliability.

CFM Requirements

Airflow capacity must match the cooking equipment under the exhaust hood system. Light-duty cooking needs roughly 150–250 CFM per linear foot of hood. Medium-duty equipment requires 250–350 CFM per foot. Heavy-duty appliances demand 400–550+ CFM per foot. A commercial kitchen with multiple fryers or charbroilers needs a fan rated for higher CFM output.

Static Pressure

Static pressure measures the resistance air encounters as it moves through ductwork. One-story buildings typically see static pressure between 0.625 and 1.0 inches water gauge. Ducted systems add roughly 0.2 to 0.4 inches per 100 feet of duct. Fittings contribute about 0.08 inches each. Insufficient make-up air raises static pressure and reduces exhaust airflow.

Grease Removal & Filtration

Grease removal protects the fan and reduces fire risk. Centrifugal upblast exhaust fans must handle grease-laden air without accumulating dangerous deposits. Proper filtration captures grease before it reaches the fan. Regular cleaning maintains efficiency and prevents smoke buildup.

Code Compliance

NFPA 96 sets critical requirements for commercial exhaust fans. These standards protect building occupants and ensure safe operation.

• Rooftop termination requires a minimum 10 ft horizontal clearance from adjacent buildings and air intakes.
• Exhaust systems need at least 3 ft vertical separation above any air intakes within 10 ft.
• Hinge kits allow safe access for cleaning without detaching the fan from ductwork.
• Motors must sit outside the exhaust airstream for safety.

For those exploring how to choose the right upblast exhaust fan, turnkey ventilation solutions simplify compliance. Professional installation ensures all commercial kitchen ventilation meets local codes.

Greenheck suits high-volume kitchens, CaptiveAire handles heavy grease, Fantech fits tight spaces, Accurex offers adjustable speed, and Halton serves budgets. The right exhaust fan depends on kitchen volume, layout, and local codes. Always verify specs against the exhaust hood and ductwork. Quality commercial centrifugal fans reduce maintenance costs and fire risk.
