I like this mod because it is simple and it works.
I think it would be even better if the only tier of air tank was steel, and the copper/bronze tiers were removed. The copper/bronze tiers just don't add much to the mod. Players typically don't spend much time on the copper/bronze tier of tools before getting to steel.
Resources come and go, and items can get lost on death or in lava, so having alternatives can be useful even after you get access to better resources. But it's also nice when you can give away the lower tier tanks to someone who has none - 10-20 uses are still very useful compared to having no tank. :)
