Drop Shield filters serve as an excellent pre and final filter for application in Gas turbines and compressors. They efficiently remove airborne particulate matter, snow, mist and fog, acting as a filter and a cleanser in one. DS rigid filters are specially designed for the elimination and drainage of free water and airborne salt crystals. Wherever placed, subsequent final filters protect not only from coarse dust but also from running in wet conditions, thus significantly prolonging their life and increasing their operational safety.
