Commercial Exhaust Hoods

Basically, commercial restaurant exhaust hoods are machines that are hanged above the cooking area to remove smoke and grease from the air and make sure your kitchen is soundly ventilated and safe from any possible fire hazards. It is a must-have for a commercial kitchen because it ensures clean air and safety for your employees and the food and because it is required by fire and health codes. So before you open your restaurant get the proper commercial exhaust hood for the type of food you offer at your establishment and make sure everything is up to code. 

Types Of Commercial Exhaust Hoods 

There are several types of commercial kitchen exhaust hoods that you can choose from based on the food you offer at your establishment or the kind of business you run. They are mainly classified as type 1 and type 2 hoods. 

Type 1 Hoods

Type 1 hoods are focused on removing the grease and the smoke, and thus they are placed above friers and such commercial kitchen equipment. They are also called grease hoods since their primary function is to eliminate the grease produced by the food you cook. Their cleaning and maintenance require special attention, yet it can be considered pretty easy with a bit of practice.

Type 2 Hoods

Type 2 hoods are installed to remove the heat and vapor from equipment that produces steam (not grease!) They are placed above ovens, dishwaters, and similar commercial kitchen equipment. These types usually utilize a standard design and also can be found under the name of condensate hoods.  

Commercial Hoods Based On Their Design Features And Purposes

Exhaust design hood packages have fans to maintain ventilation in your kitchen, but they are not sufficient on their own for a commercial kitchen since they lack the filtration system to remove grease too.  

Make-up Air Hood-Captive Air

Standard exhaust packages are the most common hoods out there, and in addition to removing vapor and heat, they are helpful when it comes to grease, too, thanks to their filters. 

Makeup-Air hood packages operate slightly differently than the other commercial exhaust hoods. They remove the excess heat and bad smells and release fresh air to maintain the air quality. If you don’t ensure the removed air is replaced somehow, your kitchen will suffer from poor air quality, which can harm both the staff and the food.  

If you don’t have access to an external ventilation system to connect your hood, you should consider getting a ventless exhaust hood. Ventless exhaust systems are self-sustaining commercial exhaust hoods that do not require to be connected to a duct to operate. Just keep in mind that these models will require extra care for their cleaning.

Installation And Fire Codes

As with many commercial kitchen equipments, commercial exhaust hoods also have codes that need to be followed when installing and cleaning to avoid any potential accidents and create a safe working environment. While codes and regulations may vary from state to state, they mostly follow the same international structure and rules. You can ensure you don’t run into any legal problems by paying attention to the details listed below. Make sure to check with your local government to find out about the ranges required for your specific location.

  • Install the hood at least 6 inches above the cooking area but do not exceed 3.5/4 feet. The elevation range depends on the type of cooking area and hood you have. Each model has its own specification set by the local codes. 
  • Fire suppression systems are a must-have if you want your exhaust hood to operate safely. The law usually requires vent hood fire suppression systems, and you cannot open your restaurant without one. If you are unsure which fire suppression is proper for you, consult the company you buy the exhaust hood from.
  • Make sure the joints are appropriately sealed during installation. Leakages can cause your kitchen to become stuffy and might harm the food you prepare. 
  • Utilize a makeup-air system to safely filter and displace the air in and out of the building.
  • Make sure to use high-quality material in the production of the hood and the ducts. Once again, your local government might require the use of specific materials (such as stainless steel of certain sizes) but using high-quality material, in general, will ensure you don’t face sudden problems in the middle of a busy day.

  • Thanks so much for talking about the different types of exhaust hoods and what each is used for. My cousin’s husband owns a restaurant and he wants to make sure he keeps his kitchen in as good shape as he can. He’s been looking into hiring some professionals to help him get everything clean and ready to use.

  • Turan, this is an excellent post! Because of the diversity of cooking equipment and greasy materials used, commercial hotel kitchens are designated as a higher fire risk zone. As a result, an exhaust hood system is necessary to remove excess heat and other airborne particles like grease-filled air. Removing oil-laden air and other buildups from the kitchen is a simple way to reduce the fire risk.
