Air compressor from fire extinguisher - video

Is that a Kinder Surprise Egg air filter?

I'm a bit worried about that fire extinguisher as an air tank. Doubt there's much corrosion allowance on that stamped carbon steel tank that's meant to hold a dry chemical. There's no easy way to drain it because all the fittings are on top. Don't know how long it'll hold up to condensation when in use. I just don't want to die due to ruptured air tank.
