GENERAL DESCRIPTION

HFC**4a is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using HFC**4a in the early ***0s as a replacement for the more environmentally harmful R**2, and retrofit kits are available to convert units that were originally R***-equipped. Other uses include plastic foam blowing, as a cleaning solvent, a propellant for the delivery of pharmaceuticals (e. G. Bronchodilators), gas dusters, and in air driers for removing the moisture from compressed air. HFC**4a has also been used to cool computers in some overclocking attempts. It is also commonly used as a propellant for airsoft airguns.
