Vacuum technology involves the creation and maintenance of a space with significantly reduced pressure, often referred to as a vacuum. This technology is essential in various applications, including semiconductor manufacturing, scientific research, and medical equipment. By removing air and other gases, vacuum systems can prevent contamination and improve the efficiency of processes. There are different types of vacuum systems, such as mechanical pumps and cryopumps, each designed for specific pressure ranges and applications. Vacuum technology plays a crucial role in industries like pharmaceuticals and aerospace, where precise control of the environment is necessary for product quality and safety.
