Rigid or folding handheld device used for cooling, air circulation, or ceremony or as a sartorial accessory throughout the world from ancient times. As evidenced by Egyptian reliefs, early fans were of the rigid type, with a handle or stick attached to a rigid leaf or to feathers. In China, the folding fan came into fashion during the Ming dynasty (13681644); much significance came to be attached to the fan in East Asia, and many great Chinese painters devoted their talents to fan decoration. Portuguese traders in the 15th century brought fans to Europe from China and Japan. Through the 19th century in the West, fan decoration and size varied with European fashion.

A fan moves gases by producing a low compression ratio, as in ventilation and pneumatic conveying of materials. The increase in density of the gas in passing through a fan is generally negligible; the pressure increase or head is usually measured in inches of water.
Blowers are fans that operate where the resistance to gas flow is predominantly downstream of the fan. Exhausters are fans that operate where the flow resistance is mainly upstream of the fan.
Fans are further classified as centrifugal or axial (see illustration). The housing provides an inlet and an outlet and confines the flow to the region swept out by the rotating impeller. The impeller imparts velocity to the gas, and this velocity changes to a pressure differential under the influence of the housing and ducts connected to inlet and outlet.
Fan types. (a) Centrifugal. (b) Axial.

Origin: 1886
While fanatics abounded in the Old World, we Americans can claim credit for inventing a kinder, gentler version: the baseball fan. It happened in the 1880s, apparently thanks to Ted Sullivan, manager of the St. Louis Browns. According to an 1887 article in Sporting Life, a Philadelphia publication, "It was Ted who gave the nick-name of 'fans' to base ball cranks. You never hear a man called a 'fiend' out in the Western League cities. 'Fan' is the word that is invariably used. It is a quick way of saying 'fanatic.'"
A few years later, in 1896, Sullivan himself explained how he came up with the term: "The first season I was with [Chris] Von der Ahe [the team owner], Chris had a board of directors made up of cranks who had baseball on the brain, and they were always interfering with me and telling Chris how the team ought to be run. I told Chris that I didn't propose to be advised by a lot of fanatics. 'Vat dat you call it? Fans, eh?' said Chris. 'Yes, fans for short. They're a lot of fans, Chris,' I said. The expression was a hit with me. Comiskey and the players took it up, and then the newspapers."
By the turn of the century, the fiends (1865) and cranks (1882) were gone. A 1901 glossary noted that fan was "common among reporters," perhaps for its innocuous sound and breezy humor. Fan would also appeal to headline writers, hungry for short words.
As the first American sport to turn professional, baseball modeled fandom (1903) for the others. And fans were too useful to confine to sports. From early in the twentieth century, entertainers of all sorts, especially movie stars, cultivated their fans, leading to such phenomena as fan mail (1924), the fan letter (1932), and fan clubs (1941). Even science fiction got into the act with fan magazines in the 1930s, known also since 1940 as fanzines.
Without qualification, indicates a fan of science fiction, especially one who goes to cons and tends to hang out with other fans. Many hackers are fans, so this term has been imported from fannish slang; however, unlike much fannish slang it is recognized by most non-fannish hackers. Among SF fans the plural is correctly fen, but this usage is not automatic to hackers. “Laura reads the stuff occasionally but isn't really a fan.”
1. An air-moving device composed of a wheel or blade and housing or orifice plate. 2. During construction or demolition of a building, an upwardly projecting arrangement of scaffolding and netting that is intended to catch any debris that might otherwise fall to the ground. Also see axial-flow fan, centrifugal fan, plenum fan, propeller fan, return fan, supply fan, tubeaxial fan, vaneaxial fan.

fan, device for agitating air or gases or moving them from one location to another. Mechanical fans with revolving blades are used for ventilation, in manufacturing, in winnowing grain, to remove dust, cuttings, or other waste, or to provide draft for a fire. They are also used to move air for cooling purposes, as in automotive engines and air-conditioning systems, and are driven by belts or by direct motor. The axial-flow fan (e.g., an electric table fan) has blades that force air to move parallel to the shaft about which the blades rotate. The centrifugal fan has a moving component, called an impeller, that consists of a central shaft about which a set of blades form a spiral pattern. When the impeller rotates, air that enters the fan near the shaft is moved away perpendicularly from the shaft and out of an opening in the scroll-shaped fan casing. As a light, flat instrument manipulated by hand to cool the body or ward off insects, the fan is of tropical origin and probably stems from the primitive use of palm or other leaves. The long-handled, disk-shaped fan carried by attendants was from ancient times associated with regal and religious ceremonies. In China an early form of the hand fan was a row of feathers mounted in the end of a handle; in Greece linen was often stretched over a leaf-shaped frame; and in Rome wooden fans, gilded and painted, were used. In Europe during the Middle Ages the fan virtually disappeared until the 13th and 14th cent., when fans from the Middle East were brought back by Crusaders and became fashionable for the wealthy. After 1500 the fan became generally popular; flag fans, disk-shaped fans, and tuft fans of ostrich plumes or peacock feathers, with handles of carved ivory or gold set with jewels, were common in women's wardrobes. In c.1600 the folding fan, developed in medieval Japan and introduced into Europe by way of China, became popular. The slats, of ivory, bone, mica, mother-of-pearl, or tortoiseshell, were delicately carved and covered with paper or fabric. The fan reached a high degree of artistry, especially in France, in the 17th and 18th cent. Delicately folded fans of lace, silk, or parchment were decorated with original designs and paintings by contemporary artists. The management of the fan became a highly regarded feminine art. The function and employment of the fan reached its high point of social significance in Japan.

Fans are used to "cool off," a common metaphor for calming down after being in a highly emotional state. Fans can also have the opposite effect, however, by increasing the power of a raging fire (by feeding it with oxygen)-the source of such expressions as "fanning the flames." Old-fashioned folding fans can symbolize both women and the phases of the moon. Finally, electric fans can represent danger because of their blades and their potential for causing electrocution.
