Edwaru mention that he dont know much about air, since none of the irregulars have been knowledgeable in the subject. But as far as I know air (oxygen) only liquify if very, very cold. And is therefore not to be found natural (needs to be made).

Shinsoo on the other hand seems to liquifi simply when the concentration is high enough.

And just to ad, high concentration will normally mean pressurization which lead to a rise in temperatur. So even though pressurization is one of the parts used in making liquifid oxygen, it only work in combination with cooling and thereafter expansion.
