In commercial cooking operations air quality is especially important. An adequate air movement system impacts life safety, fire hazard, work environment, and dining experience for patrons. Chapter 8 of NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations contains guidance for installation and operation of air movement equipment.
An exhaust fan is critical to transport inside air to the exterior of the building. An upblast exhaust fan pulls air up and out a roof termination point, without allowing water vapor, smoke, or grease to drip back into ducts. An in-line exhaust fan aligns with ductwork, generating horizontal airflow to move contaminants into the trap.
The Standard includes guidance for choosing adequate size for the operation, and access for cleaning and inspection.
