Yep, I have a 5 lb. straight CO2 tank for my beer keg, but I 
never considered using it to blow dust out of machines. Anyway, 
I'd have to figure out some type of fitting to interface with 
the ball-lock keg fitting. As you said, though, the nitrogen 
blend would be slightly safer than pure CO2.

p.s. - I think nitrogen serving gas has become over-used. It's 
fine for Guinness, Murphy's, Beamish, etc. But personally I 
think it's nasty for lighter ales and session beers.
