How do I fill a canister with oxygen?

[ZaneYates]

I’m very confused about this. I have an oxygen compressor, and many other oxygen type blocks, as well as the canisters. I’m trying to fill these canisters with oxygen so that I can fill up my oxygen tanks before going to the moon. I’m on the newest version of GC. Thank you

You need an Oxygen Collector, Canisters can only hold liquids (liquid oxygen) so you can only fill O2 Tanks.

Start here and follow the links in/on Step 5 collecting Oxygen

Oxygen Compressor is what fills them up and a Oxygen Collector supplies the Oxygen Compressor with Oxygen
