It sounds a little overpowered considering air is everywhere and you need air to live, so if they took the air away to make you powerless, you die.
 Plus with air, you could take away the oxygen and change the pressure, which I'm not sure what conduit could avoid that. 

It sounds a little like a conundrum but don't take it from me, I think you should see what Argetlam350 has too say considering it's his RP.
