This can be a concern for buildings located in residential areas or for commercial kitchens located near the office or retail spaces.

Down blast Exhaust Fans

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.
