The MicroCare MCC-DST14A Big Blast™ Canned Air Duster 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.
