Vapor Liquid Separator Tanks

Vapor Liquid Separator (VLS) or Knockout Tanks are used to remove liquids from airstreams in Soil Vapor Extraction and Dual Phase Extraction systems.

MAE2’s VLS tanks are custom designed based on air flow requirements and come in a range of sizes. The tanks can be constructed from marine grade aluminum or stainless steel. Each tank is custom built to your specification and can have inlets, site tubes, pump out and drains arranged in any orientation you choose. A full 3 CAD drawing will be provided to you for approval prior to construction.

Typical options include 2” clear site tube assembly, Single Point High level switch or multi point pump out switch, vacuum relief valve, vacuum gauges, sample ports, sturdy steel reinforced clean out plug and drain valves.
