Because these fans are mounted on the roof, they can produce a significant amount of noise that can be heard both inside and outside the building. This can be a concern for buildings located in residential areas or for commercial kitchens located near the office or retail spaces.
Downblast Exhaust Fans
Downblast exhaust fans, also known as roof-mounted downblast fans, are a type of commercial kitchen exhaust fan that is mounted on the roof of a building. These fans are designed to remove hot air, smoke, and other pollutants from the cooking area and exhaust them to the outside.
Unlike upblast exhaust fans, which draw air up and out of the building, downblast exhaust fans blow air down and out through a duct that connects the fan to the kitchen hood. These fans typically have powerful motors and large blades that are able to move high volumes of air and effectively remove smoke and fumes from the cooking area.
One of the main advantages of down blast exhaust fans is their ability to provide a more direct and efficient ventilation solution for commercial kitchens. Because these fans blow air down and out, they can help to effectively remove smoke and fumes from the cooking area and prevent them from lingering in the kitchen.
Downblast exhaust fans are also typically easy to install and maintain. Because these fans are mounted on the roof, they are relatively easy to access for installation and repairs. Additionally, many down blast exhaust fans feature removable grease trays and other components that can be easily cleaned and maintained.
One potential disadvantage of down-blast exhaust fans is their potential to recirculate air into the building. Because these fans blow air down and out, there is a risk that the air being exhausted from the kitchen can be pulled back into the building through open windows, doors, or other openings. To minimize this risk, it is important to ensure that the exhaust fan is properly ducted and that there is adequate makeup air being supplied to the kitchen.
Centrifugal Exhaust Fans
Centrifugal exhaust fans are a type of commercial kitchen exhaust fan that uses centrifugal force to move air through the system. These fans are designed to remove hot air, smoke, and other pollutants from the cooking area and exhaust them to the outside.
Centrifugal exhaust fans use a motor to spin a series of blades that are housed in a housing unit. As the blades spin, they create a low-pressure area that draws air into the fan and then expels it out through a duct that connects the fan to the kitchen hood. These fans can be mounted on the roof or wall of a building, depending on the specific needs of the application.
One of the main advantages of centrifugal exhaust fans is their ability to move large volumes of air with relatively low noise levels. The centrifugal force generated by the spinning blades allows these fans to move air more efficiently than some other types of exhaust fans, which can result in faster and more effective ventilation.
Centrifugal exhaust fans are also typically more energy-efficient than other types of exhaust fans. Because these fans are able to move air more efficiently, they require less energy to operate and can help to reduce energy costs over time.
