Modern production methods make ever increasing demands on the quality of compressed air. However, the ambient air taken in and compressed by the compressor is heavily contaminated by impurities. Moreover, depending on the compressor type, the delivered air will contain oil, which is conveyed with the compressed air in fine aerosols, together with impurieties from the compressed air network, e.g. rust and scale. In addition, any condensate formed must be removed from the system. The function of the ECOCLEAN® compressed air filters is to remove these impurieties and formed condensate, thereby preventing any damage to the downstream equipment.
