Air intake filter systems.
Static filter system.
In regions with relatively low dust concentration, a static filter system is the most practical solution. Usually a two-stage arrangement with pre- and fine filter is selected in order to achieve the required filter class and endurance. Customarily, bag filters are employed in the first and compact filter elements in the finefilter stage. For long-sustained periods of high air humidity and mist, a droplet eliminator is additionally integrated. In zones with extremely high open wetness, such as in coastal regions, an additional upstream coalescer filter system is recommended.
