A recently granted patent (Publication Number: US11918742B2) discloses a filter apparatus designed for filtering liquid from gas. The apparatus includes a first housing with a gas inlet and outlet, first and second filter media mounted in the housing, and a collection basin between the filters. The first filter media is hydrophobic, allowing droplets of liquid to fall into the collection basin via gravity. An overmolded outer structural support holds sealing rings that secure the filter media to the housing, ensuring efficient filtration.

The patent claims detail various configurations and features of the filter apparatus, such as the use of coalescing media in the first filter, the removable attachment of the second housing to the first housing, and the materials used in the second filter media. Additionally, the apparatus is designed to filter humidity, water vapor, nebulized liquid, and nitric oxide from the gas. The transparent or translucent second housing aids in monitoring the liquid level for timely removal and emptying. Overall, the patented filter apparatus offers a comprehensive solution for effectively filtering liquid from gas in various applications.
