DeWalt offers a "jobsite blower" that can work for small jobs. It comes with a long tube attachment for blowing out a workshop AND a small blower/inflator attachment. It is bigger than the other ones discussed in the comment section, like the size of a small circular saw, instead of the pistol grip/drill size.

A suggestion on this sort of thing- try a Cordless Blower. Or if you don't like green you can get Yellow or Red. Same idea.
