The unversal atmospheric element compesator is a sort of gas mask. It compensates for the elements in the atmosphere. Something similar to what the Benzite breathe in to. Those blue guys with the cat ears that breathe with that device mounted on the chest of ther uniform.
Do you have any canon evidence to support that claim? --OuroborosCobratalk 00:33, 28 March 2007 (UTC)
It is unknown what exactly this device does, but it was significant enough to be known by Spock. It can logically be deduced, however, that this device plays a role in terraforming and that it has something to do with the atmosphere.
We do not state what is unknown (as 31dot likes to say) - and behind that is just speculation. -- Capricorn (talk) 18:39, June 28, 2014 (UTC)
