A vacuum system is a technology designed to create a space devoid of matter, including air. This is achieved by using pumps to remove air and other gases from a sealed environment, resulting in a vacuum. Vacuum systems are commonly used in various applications, such as in laboratories, manufacturing processes, and even in household appliances like vacuum cleaners. These systems can be classified into different types, including mechanical pumps, diffusion pumps, and turbo pumps, each serving specific purposes. The effectiveness of a vacuum system is often measured in terms of pressure, with lower pressures indicating a better vacuum. Proper maintenance and monitoring are essential for optimal performance.
