canned air : Computer Hardware Buyers’ Glossary

canned air
A metal can containing “compressed air’. You use a blast of it to clean crumbs out of a keyboard, dust out of a fan, clean a CD/DVD (Compact Disc/Digital Video Disc) player, or dust off a computer component. It is a misnomer since it actually contains gases more easily compressed than air, e.g. difluoroethane, trifluoroethane, or tetrafluoroethane. My can of Certified Data Ultra Duster contains diflourothane, a refrigerant related to freon. I checked up on it. It has low toxicity and is not a greenhouse gas. It is ozone friendly. However the label warns you that deliberately inhaling it is dangerous and can kill you. It has a faint hospital aroma.
