An air pump is a device for pushing air. Examples include a bicycle pump, pumps that are used to aerate an aquarium or a pond via an airstone; a gas compressor used to power a pneumatic tool, air horn or pipe organ; a bellows used to encourage a fire; and a vacuum pump.
The first effective air pump constructed in England for scientific purposes was made in 1658 by Robert Hooke for Robert Boyle.[1]
