The principles of its separation function, like Vane, are based on Impingement Separation and Interception Separation. Its structure consists of a series of knitted wire mesh. The diameter of the wires is in the range of 0.1mm-0.28mm and the suggested material for them is SS-304L and SS-316L. Since the type of wires and the wettability characteristics of its surface are very important, therefore, in order to catch very small drops (less than 5 microns) of natural gas with high pressure, special fibers are also woven together with steel wires. (Co-Knitted Type).
