Choosing a Commercial Kitchen Exhaust Fan

When building a new commercial kitchen, the most important element is proper ventilation.commercial kitchen hood exhaust fan Ventilation is crucial to ensuring that all cooking appliances operate safely and efficiently. To properly ventilate a commercial kitchen, the ventilation system must include an exhaust hood. A commercial kitchen exhaust fan creates a reversed air flow through the hood to remove smoke, soot, heat, and grease from the cooking area. The hood then captures and filters these contaminants before the exhaust fan blows them outside.

Choosing the right exhaust hood will depend on several factors.commercial kitchen hood exhaust fan These factors can include the cooking equipment being used, the kitchen layout, and the size of the space. The hood needs to be large enough to adequately cover all of the equipment under it. It also needs to be positioned at the correct height so that it can vent out the smoke and odors produced during cooking. In addition, the hood must be able to meet local codes.

The type of cooking equipment in a commercial kitchen will dictate how much CFM the exhaust hood will need to be.commercial kitchen hood exhaust fan For example, open flame cooking requires more CFM than gas griddles or electric woks. The ventilation system must also be able to handle the volume of cooking that will take place in the kitchen, as well as the frequency and intensity of the cooking activity.

An exhaust hood that is equipped with a demand control kitchen ventilation (DCKV) system will provide better energy efficiency than a conventional commercial kitchen fan. The DCKV will utilize temperature and optic sensors to detect smoke and effluent in the cooking space and then automatically reduce the fan speed accordingly. This significantly cuts down on energy use and the amount of make-up air required to bring in fresh air.

Another factor to consider is the ductwork to the outside of the restaurant. The length of the duct, the number and direction of bends, as well as the insulation requirements will all affect the hood’s performance. For example, long runs with many bends will require a higher CFM than short, straight runs. The ductwork should also be well-insulated to prevent any heat loss.

When choosing a commercial kitchen exhaust fan, it is also important to consider the maintenance and cleaning of the equipment. Some fans are easier to clean than others, so it is a good idea to choose one that can be cleaned easily. This will help to minimize the risk of contamination from bacteria, mold, and other germs that can accumulate on the fan.

Lastly, it is important to remember that all commercial kitchen exhaust fans must be installed by a licensed and insured professional. A qualified technician will ensure that the hood is correctly sized and placed for optimal performance. The technician will also install the hood at the correct height and in accordance with local codes. They will also be able to provide recommendations on the best way to install the rest of the ventilation system.
