We offer high-quality gas transfer pumps used to pump large gas streams, which compress the gas entering the vacuum object to another pump or release it into the atmosphere, thus removing it. You can also choose gas trap pumps (oil-free), which trap the gas using various physical principles, such as by freezing to a solid state on the surface, chemically bonding gas with specially designed materials, absorbing, or otherwise, and are used to extract ultra-high vacuum.
