Are there any rebreather systems that operate off of a standard tank of air rather than Nitrox, Heliox etc.? Hoe do these work to be efficient and control the ppo2 levels? Thanks for your help!

Any CCR can use air diluent. Nitrox is frequently used in SCR and air can be used in SCR units but should not be used in shallow water so you won't find it in a single gas rebreather. The Azimuth and other SCRs with gas switching abilities can use air for the deeper parts of the dive.
