Gas containing entrained liquid mist or fog, dust, rust, or scale (singly or in combination) enters the vessel through the inlet connection into the large inlet chamber ahead of the coalescing elements. This allows the gas to distribute around the coalescing elements for efficient use of the available filter surface area. Solid particulate materials are trapped by the filter element fibers as the gas and liquids pass through. The liquid mist or fog is retained by the fibers of the filter element until enough liquid accumulates to form a large drop. The gas then forces the large drops through the filter element. These large drops are then separated from the gas by gravity or by the action of the mist extractor section.
The liquid accumulates in the liquid chamber where it is removed by the action of the liquid level controller and dump valve. The gas, free from its particulate contaminants and liquids, leaves the vessel through the gas outlet.
