The Electrolyser Multiblock - Obtaining Oxygen
This guide was written by therobbie72 in official wiki
You will need to produce oxygen to breathe while on the moon. Oxygen is produced by the Electrolyser multiblock.
The Oxygen Loader from Ad Astra will NOT produce oxygen from water. The Oxygen Loader is used to transfer oxygen into space suits and oxygen tanks. Oxygen must be pumped into the Oxygen Loader using Create pipes
NOTE: Because the Oxygen Loader only transfers oxygen, it does NOT require power. The Electrolyser multiblock takes a 3x3x3 space and consists of 3 different blocks: Electrolyser (Custom Machinery), Copper Casing (Create), and Copper Coil Block (createastral). These blocks are built into the following configuration:

The Electrolyser block will have two visible holes; one in front, and one below. Water can be pumped into one of these holes, and the oxygen produced can be pumped out of the other.
