The raw gas flows through the inlet pipe 5. At a meeting of the gas flow from the outlet 6 e.g. the free movement of gas is changed from horizontal to vertical, and at the outlet 6 of the first branch of a large liquid droplets and solids, which under the action of gravitational forces fall into the cavity I. Then the gas goes through the pipe 7 and the output from it falls on the reflector 8, where the second branch of the large impurities that fall into the cavity I. Gas containing mainly small particles, changes direction by 180°, rises up and the pipe 10 enters the annular gap 25. As the pipeline 10 is oriented along the tangent to the generatrix of the surface of the housing 4 and at an angle thereto, the gas gets swirling movement in the annular gap 25 and up, enters the space between the first 45 and second 46 plates of the cassette 21. Impurities deposited on the partition wall 23, through the drain pipe 29 are received in the cavity II. Next, the gas passes through a tangential slot grooves 53 and receives a twist in the gap between the filter element 47 and the inner surface of the casing 48. Under the action of centrifugal force, there is a further separation of the phases of the purified gas. Weighted phase, moving spiral thread on the periphery of the inner surface of the casing 48, enters the annular gap 55 and through the window 56 is deposited in the cavity II. The phase with the smaller impurities revolves around the filter element 47. The gas passes through the filter mesh filter inside the ith element 47, through the outlet 59 of the filter element enters the collector under the cover 19, and then through the outlet 9 purified gas is delivered to the consumer. Smaller particles settling on the filter grid, under the action of the swirling flow moving in a spiral down, fall on a perforated partition wall 50, and it is deposited in the cavity II. A minor part of the gas which has passed through the septum 50 and the window 56 in the cavity II bunker 1, under the effect of dilution arising under the G-shaped wall 27, is sucked through the holes 26 and connects with the gas flowing through the pipeline 10.

Impurities deposited in the cavities I and II, due to the large amount of moisture in the treated gas, have a liquid phase. Upon reaching the liquid phase level sensor upper position 15 or 16, respectively, are included discharge valve 13 or 14, the drain in the drain line. Upon reaching the liquid phase level sensor lower position 17 or 18, respectively, is cut off discharge valve 13 or 14.
