An air compressor is a device that converts power
(usually from an electric motor, a diesel engine or a gasoline engine) into
kinetic energy by compressing and pressurizing air, which, on command, can be released
in quick bursts. There are numerous methods of air compression, divided into
either positive-displacement or negative-displacement types
Air compressors
have been around for literally thousands of years. Now granted the devices the
ancients used for compressing air bear little resemblance to the modern air compressor. However, the
basic principle is the same and without the primitive air compressors, civilization
would not have evolved as fast it has. One of the primary uses for compressed
air was to increase the combustion in a furnace. The operator of a forge would use
a bellows to blast compressed air into the furnace to stoke up the heat. This
allowed ancient man to produce stronger and better metals for tools and
weapons. Most people today would not equate a bellows as an air compressor, but
that is exactly what it is. The blacksmith would pull apart the handles on the
bellows and a check valve would allow fresh oxygen to rush into the accordion
like chamber. Then using muscles as the power source, the blacksmith would
squeeze the handles together and the compressed air would shoot out the fitting
on the end. Using this process it became possible to create a fire hot enough
to smelt ores of copper, tin, lead and iron. Bellows are still used today in a
variety of applications. The organ at your local church is probable powered by
a bellows that is practically identical to one a thousand years ago. They even
pop up in medical applications such as breathing machines in operation rooms.
It wasn’t until later in history that it became possible to compress air using mechanical methods. In the past, only human and animal power was possible to power crude air compressors and this severely limited the utility of these primitive devices. With the industrial revolution, the mechanical compressor was born. Engines running from steam power became the first method to power these compressors. One of the first uses of a steam powered pneumaticcompressor was in underwater diving equipment. This opened up whole new methods for under water e
