Coalescing separator insert, coalescing separator, and process for manufacturing a coalescing separator insert

A coalescing separator insert for separating liquid from a gas flow that flows through the coalescing separator insert in a flow direction from an exterior to an interior of the coalescing separator insert or from the interior to the exterior of the coalescing separator insert, the coalescing separator insert comprising:

• at least one first coalescing separator body comprising at least one first coalescing separator medium configured to separate liquid from the gas flow by coalescence;
• an air-permeable, cylindrical first support tube configured to support the at least one first coalescing separator body, wherein the at least one first coalescing separator medium is arranged around the air-permeable, cylindrical first support tube;
• at least one second coalescing separator body comprising at least one second coalescing separator medium configured to separate liquid from the gas flow by coalescence, wherein the at least one second coalescing separator medium is arranged downstream of the at least one first coalescing separator body in the flow direction of the gas flow and is arranged concentrically to the at least one first coalescing separator body;
• wherein the at least one second coalescing separator medium is wound, at least in sections, into a multi-layer winding;
• wherein the at least one second coalescing separator body comprises, at least in sections, at least two layers of the at least one second coalescing separator medium arranged overlappingly relative to each other in the flow direction of the gas flow;
• wherein the at least two layers of the at least one second coalescing separator medium arranged overlappingly relative to each other are connected to each other at least in sections for fixation of the multi-layer winding.
