The short answer is, many things. Vacuum pump solutions save energy, money and time. They also improve product quality, extend shelf life, make processes safer, speedier and smoother, cut pollution, and even help save lives. The range of vacuum technology is quite breath-taking. It plays a role in the production of food, medicines, explosives, wind turbines, district heating, stainless steel, and much more. It also contributes to game-changing high vacuum research in physics and chemistry. However, the fundamental role of a vacuum system, its science, still remains the same: reduce the number of gas particles in a system which, at constant temperature, corresponds to a reduction in gas pressure. And this is a process that continues to affect our lives every single day.
