Compressed Air Cans

Canned air or compressed air, is a product used to force air through an airtist airbrush, or clean electronic equipment and other sensitive devices that cannot be cleaned using water. Despite the name "canned air," the cans actually contain gases that are much easier to compress into liquids, such as difluoroethane, trifluoroethane, or tetrafluoroethane (the main components of air, which are oxygen and nitrogen, are in fact very rarely used). Hydrocarbons, like butane, were often used in the past, but their flammability forced manufacturers to use fluorocarbons.
