Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.
Compressed air dryers utilize technologies such as refrigeration, desiccant adsorption, and membrane filtration to remove contaminants, particularly water, from the air.
Gas purifiers, dryers and filters are used to purify gases in a process stream. They are used to reduce or eliminate point-of-use impurities in gases such as helium, hydrogen, methane, nitrogen, and carbon dioxide.
