POWERCLEAN Gas Dusters by American Recorder Technologies are environmental friendly, high-tech gas dusters that use non-toxic, non-flammable and residue free carbon dioxide and nitrogen gases. These gases are ideal for cleaning all types of delicate electronics and optics, as well as many types of household and office devices. You only need to purchase the precision valve once and simply replace the steel gas cartridges when empty (which by the way are 100% recyclable).
Don't be fooled by aerosols that claim to be "canned air" (there is no such thing - read the label). Those aerosols actually use chemical propellants that emit harmful vapors and can leave a residue. Use genuine POWERCLEAN products for better performance, safety and health.
