Hollow and flat glass production, like the manufacture of special glass, faces major challenges such as efficiency improvements and the reduction of CO2 emissions. Energy management in compressed air supply and the high demands on compressed air quality is among the central tasks. It is Donaldson components of filtration technology and adsorption technology that contribute worldwide to ensuring that compressed air and gases, as well as process water, are available for glass production in defined quality and in compliance with economic and ecological specifications.
