Micro•Blast™ is the environmentally progressive answer for dry precision cleaning. This economical "canned air" is ultra pure, double filtered to 0.2 microns for the very best cleaning results. It also uses a special valve which doubles the "pushing power" when compared to old syle dusters. Importantly the cleaner is non-flammable. This means that unlike sophisticated products, it can be safely used on energized equipment, making it ideal for speedy trouble shooting. The cleaner is non-conductive, non-toxic, odor-free, non-corrosive, non-flammable and leaves no residue.
