Water Filtration Machine (Subnautica)

The Water Filtration Machine is a Placeable Item and is constructed by the Builder. It can only be built as a wall module in the Room Seabase module. The Water Filtration Machine utilizes Energy from the seabase to desalinate the ocean water. It will slowly produce Salt and Big Filtered Water. The Water Filtration Machine has an internal storage of four items and will stop working once it is filled. When added to a base it will lower the Hull Integrity by 2.0 unit. It is the only non-seabase module known to do this.

You can now find the fragment inside Wrecks.
