Fan (machine), power-driven device that produces a flow of air or gas. Mechanical fans move air and gases through ventilating systems, force air through steam boilers, lower the operating temperature of electronics and machinery, and serve numerous other industrial needs. Fans operate at relatively low pressures. When a high-pressure blast of air or gas is needed, an air compressor is used instead of a fan. There are two principal types of fans: centrifugal fans and propeller fans, sometimes called axial fans. Centrifugal fans have been manufactured for more than 250 years, and have changed little in design since their invention. The centrifugal fan's air intake is parallel to its axis of rotation, and its discharge is perpendicular to the axis of rotation. Centrifigal fans are commonly used for ventilation, as in ceiling-mounted bathroom fans. The blades on a centrifugal fan are manufactured in three general types: radial blades, forward-curving blades, and backward-curving blades. Each type of blade has different performance characteristics. Higher operating speeds are generally possible with backward-curving blades. Propeller fans are commonly used for ceiling fans or desk fans. The propeller fan's air intake and discharge are parallel to its axis of rotation. The fan's blades may be shaped with cross sections similar to the airfoils that give lift to a plane's wing, or they can take the form of flat or curved plates 1. What is the text above? Answer: 2.
