Keep items filtered with this mechanical device. It needs to maintenance and uses a simple valve to get air to move from the container with ease. This works with a second valve that works after the first valve lets old air out. The second valve will let steam come in so items can be sterilized. This will then close itself up to keep the load sterile as soon as the complete process of cleaning the system is maintained the right way. This is useful to help keep items clean and safe for people to work with.
