<p>According to the invention a gas filtration unit comprises a liquid container (10) and a number of intake gas inlet tubes (32) which extend downwardly into the container (10) and opening just above a high liquid level (24) within the container. A filtered gas outlet (20) is formed above the high liquid (24) level in the container and a displacer (38) connected to a choke vane (36) is adapted automatically to vary the liquid level between the high liquid level (24) and a low liquid level (40), which is below the inlet tube opening, in dependence on the gas flow through the container.</p> |
