Types Of Restaurant Vent Hoods:
Type 1 Vent Hoods: Type 1 restaurant vent hoods serve the crucial purpose of removing grease-laden vapors, heat, and smoke generated during cooking. These commercial vent hoods are commonly equipped with fire suppression systems and feature grease-rated ducts to comply with relevant codes like NFPA96, The International Mechanical Code (IMC), and the International Building Code (IBC). In addition, Type 1 vent hoods are outfitted with grease-rated exhaust fans to ensure efficient ventilation and safety.
Type 2 Vent Hoods: Type 2 restaurant vent hoods are specially designed for areas where heat and steam are produced without grease vapors, such as dishwashers, convection ovens, and steamers. These hoods, also known as condensate hoods, steam hoods, and dish hoods, typically do not incorporate fire suppression systems. Moreover, exhaust fans used in Type 2 applications do not require a grease rating. It's important to note that the duct requirements for these hoods differ from Type 1 hoods. For the most accurate information regarding hood design and installation, it's advisable to consult with the local inspector or the Authority Holding Jurisdiction (AHJ) and confirm any additional installation prerequisites.
