A Beginners Guide to Commercial Range Hood Systems

Tips for Commercial Range Hood Purchases

A commercial range hood is a vital piece of equipment in any commercial kitchen. Manufactured to vent heavy smoke, grease and odors from commercial kitchens, they remove hazardous pollutants from the air, help reduce grease and smoke buildup and maintain the air quality throughout your restaurant. These powerful systems are made of durable materials, can be placed side by side, or over one large unit above the cooking area and often come complete with fire suppression system to reduce the risk in case of a fire. 

As important as a commercial hood system is, it is also the law that every restaurant must have the proper unit installed. Since it greatly impedes upon the health and safety of your kitchen staff as well as your diners, it is imperative that you understand the basics of commercial range hoods. 

Types of Commercial Range Hoods 

There are two type of commercial range hoods, type 1 and type 2. Type 1, also known as grease hoods, are designed to be able to exhaust grease, oil, and smoke as well as heat, moisture, and odors from the kitchen. They include removable filters that help extract the oil and grease from the air before it enters the rest of your ventilation and duct system. It also usually contains a fire suppression system as mentioned above.

Type 2 filters, also known as pizza hoods or condensate hoods, exhaust heat, moisture and cooking odors, but not grease and smoke and heat. They can be found on dishwashers, steamers, steam tables and certain types of pizza ovens that have built in hoods. Certain types of convection ovens also don't require a hood vent since use a fan to circulate the air inside the oven.

Equipment That Goes Under Your Commercial Range Hood

Most commercial kitchens can function with one commercial range hood to take care of its main cooking area, with that area containing a range, broiler, griddle, and gas fryer. Placing this cooking equipment together will eliminate the need for more than one commercial range hood. Depending on your menu, you may also need a grease hood to filter grease vapors during food preparation. If you only need to cover a steamer, pizza oven, dishwasher or other similar equipment that doesn’t produce grease vapor, a condensation hood or heat hood will suffice.

Commercial Range Accessories

Exhaust Fan

You will need to attach an exhaust fan to your commercial range hood in order to draw air and fumes up and out of the building. The speed and size of the exhaust fan will be determined by the size and type of your commercial range hood; the equipment under the hood; and the location of you kitchen’s cooking area. Whether the cooking area is located in the center of the kitchen or up against a wall will make a difference in the speed and size of the exhaust fan.

Supply Air Fan or Make Up Air Fan

Some areas of the country require food establishments to have fans that will also put air back into your kitchen, either a supply air fan or a makeup air fan. But, even they aren't required by law, it is still a good idea to install them in order to balance air pressure in your work area.

Fire Suppression Systems

Another worthwhile installation is a fire suppression system as a precaution to a stove fire in your commercial kitchen.Air fans and fire suppression systems, while not always required in commercial kitchens are great safety features to consider for the safety of your employees as well as for your equipment.

Resources For Purchasing Your Commercial Range Hood

Purchasing a commercial range hood is best done via your food service equipment vendor. Any reputable, local commercial range hood dealer will have all the information you will need not only to purchase the correct range hood that meets the code specifications of your area, but they should also be able to evaluate what type and size of commercial range hood you will need.
