kitchen hood

A kitchen hood or cooker hood may be a device containing a mechanical fan that hangs above the stove or cooktop within the kitchen. It removes airborne grease and combustion products and fumes some smoke and heat, and much steam from the air by evacuation of the air and filtration. In commercial kitchens, hood s are often used in combination with fire suppression devices in order that fumes from a grease fire are properly vented and therefore the fire is put out quickly. Commercial vent hoods can also be combined with a fresh air fan that pulls in exterior air, circulating it with the cooking fumes, which is then drawn out by the hood.

In most exhaust hoods filtration system removes grease and other particles. Although many vents hoods exhaust air to the outside, some recirculate the air to the kitchen. In a recirculating system, filters may be used to remove odors in addition to the grease.

The device is understood as an extractor hood within the UK as a variety hood within us and as a range hood in Australia. It is also called a kitchen hood or stove hood or exhaust hood or a cooker hood or vent hood or ventilation hood. Other names include cooking canopy or extractor fan or fume extractor or and electric chimney.

An extractor hood consists of three main components such as a skirt or capture panel to contain the rising gases and one or more grease filters and a fan of tangential blower for forced ventilation.

There are two major configurations of extractor hoods such as ducted (or vented) application and ductless application. In a ducted application the output collar of the extractor hood's blower motor is attached to a duct system that terminates outside the building. In a ductless application, a filter, often containing activated carbon , removes odor and smoke particles from the air before releasing the cleaned air back to the kitchen.
