ELECOM Air Use 350ml ECO Dust Blower 3 Bottles Duster, Upside-Down OK, (CFC-Free), AD-ECOMT,

Non-CFC type No CFCs are used. The global warming potential (a numerical value indicating the degree of impact on global warming) is 1 or less. We do not use ozone-depleting substances or hydrofluorocarbons (so-called alternative chlorofluorocarbons). Can be used upside down! A safe design that prevents coolant from spraying out no matter what angle it's used at. * The coolant can cause deterioration of plastic products and damage to equipment, and is dangerous as it can cause frostbite if touched. Furthermore, it increases the concentration of gas in the air, making it more susceptible to ignition from nearby flames.
