All About Commercial Kitchen Exhaust Systems
Commercial kitchen exhaust systems are installed for the purpose of removing grease, heat, vapors, steam and odors from the cooking area, and for returning fresh air to the kitchen. There are a number of components that make up the system including, the commercial vent hood, the filters, the exhaust fan, the ductwork and the replacement air system. Each of these components plays a specific role in keeping the kitchen clean and safe.
Components of Commercial Kitchen Exhaust Systems
The exhaust fan is comprised of several sections, including filters and baffles that are intended to cool the air and contain any grease or food particles that come from the cooking surface. These components must adhere to specific codes and regulations regarding the proper size, type and installation of the commercial exhaust hood and ventilation system. Failure to follow these codes will result in violations during required inspections, but more importantly, it can increase the risk of fire or health hazard.
Commercial Kitchen Ventilation Systems: Type 1 vs. Type 2
Commercial kitchen exhaust hoods are the starting point of the commercial kitchen ventilation system. There are essentially two main types of commercial vent hoods that are used, Type 1 and Type 2. The major difference between the two types is that Type 1 commercial hoods are equipped to handle grease removal from the air, while Type 2 hoods are designed for use in commercial kitchens without grease producing appliances (e.g., no grills, broilers or fryers). Size matters when it comes to a commercial hood selection. For best results, the exhaust hood should be designed to be approximately 6 inches wider than the cooking area it is covering.
Maintenance of Commercial Hoods
The commercial hood is generally made from stainless steel, which is easy to clean and maintain. Daily cleaning of the interior and exterior surfaces of the hood will keep it as good as new for a long time. Periodic cleaning of the baffles, filters, fans and ductwork is necessary for keeping the equipment in good working order and to avoid straining the motors, which can lead to electrical fires and poor ventilation. Take care of your commercial hood, and it’ll take care of your kitchen ventilation needs.
