Kitchen exhaust cleaning (often referred to as hood cleaning) is the process of removing grease that has accumulated inside the ducts, hoods, fans and vents of exhaust systems of commercial kitchens. Left uncleaned, kitchen exhaust systems eventually accumulate enough grease to become a fire hazard.
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...
Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, ...
A kitchen hood, exhaust hood, hood fan, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. [ 1 ]
Blowers provide clean air to prevent contamination of electrical and optical surfaces from dirt, corrosive gases and overheating. Mains electricity is responsible for powering the blower’s motor. Different power ratings ensure that the required air flow is provided under different application conditions, duct pressures and hose lengths.
These fans move the air parallel to the fan's axis of rotation. The screw-like action of the propellers moves the air in a straight-through parallel path, causing a helical flow pattern. [citation needed] The three main kinds of axial fans are: Propeller fans - These fans are used to move large quantities of air against very low static pressures.
A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. [1] An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary ...
