This design is used to control water pressure levels for all types of water including city-piped water. It uses a vacuum filter and distiller to keep reflux from developing and can work with two aspirators. It has a cooling coil that works to keep the vacuum effect from being lost due to the increase in the temperature of the water. The vacuum controller can also be designed with a material used to help check on how functional it is. The bath is also made with a sturdy polypropylene body to keep it strong for an extensive period of time.
