If by "air" you mean Oxygen, yes. All animals (except for that crazy jellyfish they found) needs oxygen to survive. A hermit crab's gills will filter the oxygen (or "air") out of the water.
Even land hermit crabs have modified gills that need to stay moist in order to perforn the same task. If their gills dry up, they suffocate.
