Filtration is an essential part of air purification. Air naturally contains various wastes like dust, moisture or various forms of hydrocarbons. These polluting agents from compressed air interact with each other and generate possible abrasive and corrosive emulsions which can accelerate the wear of downstream equipment. Line filters thus have to remove dusty and oily contaminants carried in compressed air. Through filtration air becomes clean and of the highest quality, thus meeting the requirements of the most sensitive applications.
