Not really.For an explosion to do obliterating damage it needs a sort of shrapnel. Causing explosions by air only really causes a massive shockwave that can propel things, or burn them. It's not like harpy girl couldn't put a hole in you with compressed air.

Quote taken directly from the character sheet. Such an explosion, regardless of whether or has shrapnel or not, is still a shockwave capable of tearing a leg apart if it is close enough. It does say "annihilating" after all.
