Air compressors have been around for literally thousands of years. Now granted the devices the ancients used for compressing air bear little similarity to the contemporary air compressor. The basic concept is the very same and without the primitive air compressors, civilization would not have actually progressed as fast it has. One of the main usages 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 heater to stoke up the heat. This allowed ancient tribes to produce more powerful and much better metals for tools and weapons.
Many people today would not equate a bellows as an air compressor, however that is precisely what it is. The blacksmith would pull apart the handles on the bellows and a check valve would allow fresh air to hurry 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. Utilizing this process it ended up being possible to develop a fire hot enough to smelt ores of copper, tin, iron and lead. Bellows are still used today in a Range of applications. The organ at your Local church is probable powered by a bellows that is almost identical to one a thousand years ago. They even appear in medical applications such as breathing machines in operation spaces.
Engines running from steam power ended up being the first technique to power an air compressor. One of the very first uses of a steam powered air compressor was in undersea diving equipment. Steam powered rock drills ultimately offered way to drills powered by air compressors. Today for Commercial use, membrane compressors are quite popular for process gasses.

As the internal combustion engine got popular, they started to be used as a power source for air compressors. Gasoline engines are today typically utilized in piston type air compressors. This would be a typical air compressor you would discover in your garage or on the back of a service truck. The gas engine drives a crankshaft and piston. As the piston moves into the downstroke postion, air streams into the cylinder on the low pressure end.
When the upstroke begins, air moves into the high pressure. This action produces compressed air. In bigger industrial applications, a rotary type air compressor is utilized. Rotary air compressors produce compressed air by turning a vaned rotor within a long enclosed chamber. As the engine spins the rotor, air is drawn inside the chamber. The air is then forced down the vanes into smaller sized and smaller sized locations. This action compresses the air and forces it out the other end. Rotary vane air compressors work very well in commercial applications due to the fact that they can producing large quantities of compressed air for prolonged time periods.
Now given the devices the ancients used for compressing air bear little similarity to the modern-day air compressor. Engines running from steam power became the very first technique to power an air compressor. Steam powered rock drills eventually provided method to drills powered by air compressors.
Rotary air compressors produce compressed air by turning a vaned rotor inside of a long enclosed chamber. Rotary vane air compressors work extremely well in commercial applications since they are capable of producing large quantities of compressed air for extended durations of time.
