So where exactly did compressed air come from? How did it become so widely used and where will it go? Both of these are great questions and the answers lie below.
Compressed air can be traced all the way back to the classic bellows that were used to fuel blacksmith fires and forges. These started as hand pumped bellows, they then scaled up to foot pumped, multiple person pumped, oxen or horse driven and then eventually waterwheel driven. All of these methods came about due to the demand for more and more compressed air. These bellows did not generate near the amount of air pressure or volume needed for modern day practices yet they worked in the times. These early bellows pumps would even supply miners with air.
With the evolution of metallurgy and industry these bellows were replaced by wheel driven fans, then steam came about and began generating more industrial sources of power. The main issue with steam was that it would lose its power over longer runs of pipe due to condensing in the pipes. Thus the birth of the air compressor was born. One of the largest projects that is noted to first use compressed air was in 1861 during the build of the Mont Cenis Tunnel in Switzerland in which they used compressed air machinery. From here the constant need and evolution for on-demand compressed air expanded. The picture below showcases two air compressors from 1896.
The compressors evolved over time from single stage, to two-stage reciprocating, on to compound, rotary-screw compressors, rotary vane, scroll, turbo, and centrifugal compressors with variable frequency drives. The efficiency of each evolution has continued to increase. More output for the same amount of input. Now we see a two-stage compressor, considered old technology, and wonder how the company can get any work done.
All of the technological advances in compressor technology were driven by the demand sides of the compressed air systems. Companies needed to power more, go further, get more from less, ultimately increase production. With this constant increase in demand, the supply of compressed air increased and more efficient products for using compressed air began to evolve so the air was used more efficiently.
Enter EXAIR, we evolved the blowoff to meet the increasing demands of industrial companies to get the same amount of work done with less compressed air. We have continually evolved our product offering since 1983. It all started with just a few typed pages of part numbers and has evolved to a 208 page catalog offering of Intelligent Compressed Air Products® for industry. We will also continue to evolve our product designs for continued improvement of compressed air usage. This is all to better help companies retain their resources.
If your company uses compressed air and you aren’t sure if it is efficiently being utilized, contact an Application Engineer. Thanks for joining us for the brief history lesson, we look forward to hearing from you and seeing what the future brings.
