I install the ionizing guns with a large silica gel moisture trap right next to them to guarantee the dryness. Compressed air lines are notorius for containing all sorts of contaminants and air blow off guns usually require safety precautions as they may exceed noise limits as well, besides the ESD hazard.

In any case, most compressed air is too dirty for using on electronic assemblies. Brian Barbara J.
