Vacuum Systems Use Air Pumps

I remember when I was eight one summer ago, waking up to a jackhammer splitting up and breaking down the black surface that covered our roads in front of the house. The noise was deafening, the rumblings shook from the inside, and once I was awakened by the racket, I could never get back to sleeping again. How was the ear-splitting noise made, and how could the man operating the jackhammer tolerate it? I have learned since then that air pumps are part of what makes that awful sound and the guy who was operating it was wearing heavy-duty ear plugs. 

Air pumps force the air out of a machine in moderate to high pressures. They are different from fans because fans just move air and they do not generate a force of air, or any gas in between two spaces at lower pressures. Air pumps are especially important in vacuum systems. The air pumps have to be specifically made to take out the atmosphere from an enclosure, and keep it from coming back. One or more intake fans with outlet pipes, a power source and seals make up the air pump that equalizes the differing air pressures' natural tendency

Vacuum systems can be different in construction, degree of vacuum, size, etc., and the air pump must fit the exact specifications in order to maximize its effectiveness. It ranges from small, single fans to multiple fans made with thick steel or a similar enclosure. Air pumps are vital in many types of industrial applications and manufacturing, including medical technology and research, medical instruction, instrumentation design, dentistry, surgery, and chemical and biological laboratories.

Vacuum pumps are useful and versatile devices that can be applied in a wide spectrum of industries. They are often life-savers when used in biological or chemical researches, or in medical settings.
