Description
Air is primarily used to create breathable, pressurized rooms that eliminate the need for EVA suits for humans. It is, however, ill-fitted for use in an EVA suit's oxygen supply, as the nitrogen will not be filtered out of the helmet, which, over time, lowers oxygen concentration in the helmet to unbreathable concentrations. When filling tanks in a nitrox environment, it is advised to use nitrogen filters alongside carbon dioxide filters in the EVA suit to keep the oxygen concentration high in the helmet.
Breathable atmosphere: composition
For a human player, in order to open the helmet safely, a room atmosphere with at least 21 kPa oxygen (O2) is safe to breatthe and does not generate lungrelated warnings. An enviornment with at least 16 kPa O2 partial pressure is sufficient (will give lung warning but no damage).
The presence of other inert gasses (nitrogen, carbon dioxide, water) is allowed and not harmful for breathing. It mis advisable to add other gasses, to allow plant growth,to increase heat capacity or reduce the risk of ignition.
The presence of some other gas fractions (pollutants, nitrous oxide, volatiles) is harmful for the human player. It will result in warnings in low quantities and damage or loss of consciousness when present in larger quantities.
Breathable atmosphere temperature
Air should be maintained within temperature limits in order to breathe normally as well. If it is too cold or too hot, with open (or without) helmet, it will cause the player to have heavy breathing and/or take lung damage.
A human player can breathe normally with a room air temperature between 15 and 40 degrees? <to check and add:> Colder or hotter air will give heavy breathing and ultimately cause lung damage?

Default air is defined in game as a mixture of 75% nitrogen to 25% oxygen.
