An instrument used for producing artificial currents of air, by the wafting or revolving motion of a broad surface
An instrument for cooling the person, made of feathers, paper, silk, etc., and often mounted on sticks all turning about the same pivot, so as when opened to radiate from the center and assume the figure of a section of a circle.
Any revolving vane or vanes used for producing currents of air, in winnowing grain, blowing a fire, ventilation, etc., or for checking rapid motion by the resistance of the air; a fan blower; a fan wheel.
An instrument for winnowing grain, by moving which the grain is tossed and agitated, and the chaff is separated and blown away.
A small vane or sail, used to keep the large sails of a smock windmill always in the direction of the wind.
To cool and refresh, by moving the air with a fan; to blow the air on the face of with a fan.
To ventilate; to blow on; to affect by air put in motion.
To winnow; to separate chaff from, and drive it away by a current of air; as, to fan wheat.
A ventilator to exhaust or blow the air current necessary to circulate the mine roadways and workings. feeder. Very small fissures or cracks through which methane escapes from the coal. As working faces are advanced, fresh feeders are encountered in each fall of coal. A small stream of gas escaping from a coal crevice.
A blower that circulates air and keeps components from overheating.
The cooling mechanism built into computer cabinets, laser printers, and other such devices to prevent malfunction due to heat buildup. Fans are the main source of the continuous humming associated with computers and other hardware.
a device for creating a current of air by movement of a surface or surfaces
separate from chaff; "She stood there winnowing grain all day in the field"
Otherwise referred to as a "blower". A mechanical device which creates air flow. Typical furnace blower assembly is a motor driving a squirrel-cage type fan in a metal housing.
An electrically or mechanically driven device that is used to pull air through the radiator or oil cooler. Heat is transferred from the hot oil or water in the radiator to the moving air.
A fan is used to pull air through a radiator or oil cooler. Heat is transferred from the hot oil or water in the radiator to the moving air.
Any device that creates air currents.
A device for moving air and dust through the system. If the fan is on the dusty side of the baghouse pushing the dusty air through the baghouse, it is called a positive system. If the fan is on the clean airside of the baghouse pulling the dusty air into the baghouse, it is called a negative system. (80% of all baghouses are negative systems.)
air moving device consisting of a motor impeller and housing – sometimes called a blower.
A rotary bladed machine which continuously supplies energy to the air or gas passing through it. There are three main components to a fan: the impeller (sometimes referred to as the wheel or rotor), the means of driving it, and the casing.
A device used for moving or producing artificial currents of air.
A device that produces a pressure difference in air to move it.
A device that creates air flow.
a device used to move or circulate volumes of air
Device used to move air by pulling air in from one side and pushing it out the other. Ideally, fans move hot air away from one area and move cool air in.
A device that creates currents of air, sometimes built in electric heaters to push air out from the unit.
A device designed to move air by sucking air into one side and pushing it out the other. Fans are a necessary part of most computing devices because microprocessors...
Device with rotating blades for drawing cooling air through the radiator or around the engine cylinders. Other fans are used in the heating/cooling system to circulate air to the interior of the vehicle.
A device for moving air. The fan design may be either an axial flow propeller or centrifugal blower. The fan can be applied as induced draft or forced draft.
Radial or axial flow device used for moving or producing flow of gases.
A radial or axial flow device used for moving or producing artificial current air.
Usually refers to the fan mounted to the back of the radiator. Either electrically driven or drive beld driven, it is usually mounted on the radiator to force air through. The fan draws air through the radiator to cool the liquid in the cooling system when the car is standing still, operating at low speeds, or when the air conditioner is running. In some cars, an electrically driven fan is controlled by a thermal sensor in the cooling system.
A rotating, multi-bladed device (usually 4 or more blades) for moving volumes of air in ducts with only a small pressure increase.
A fan that keeps its surrounding cool. afarsituu View
Device which consists of one or more revolving blades or vanes which are attached to a rotary hub and operated by a motor and is used to move air for cooling or to force air into the firebox of a boiler.
A machine consisting of a rotor and housing for moving air or gases at relatively low-pressure differentials.
A power-driven machine that moves a continuous volume of air by converting rotational mechanical energy to an increase in the total pressure of the moving air.
A device that moves and/or circulates air and provides ventilation for a room or a building.
