Vacuum technology involves creating and maintaining a space with very low pressure, where the number of air molecules is significantly reduced. This technology is essential in various fields, including electronics, pharmaceuticals, and space exploration, as it allows for processes that cannot occur in normal atmospheric conditions. In vacuum systems, pumps are used to remove air and other gases from a sealed environment. Common types of vacuum pumps include rotary vane pumps and turbo molecular pumps. These systems enable applications such as vacuum packaging, thin film deposition, and electron microscopy, enhancing product quality and performance.
