Abstract
Official abstract text for this publication.
The present disclosure relates to a filter apparatus for filtering liquid from a gas, the apparatus having a first housing having a gas inlet and a gas outlet; a first filter media disposed in the first housing; a second filter media disposed in the housing; and a second housing forming a first collection basin disposed in the flow path between the first filter media and the second filter media, so that a path is defined for the gas flowing from the inlet, through the first filter media, past the collection basin, through the second filter media, and to the outlet. The present disclosure also relates to a method of passing a gas through a coalescing filter media and through a hydrophobic filter media.
First claim
Opening claim text (preview).
What is claimed is: 1. A filter apparatus for filtering liquid from a gas, comprising: a housing having a gas inlet and a gas outlet; a first filter media disposed in the housing; a second filter media disposed in the housing; a first collection basin and a second collection basin disposed in a flow path between the first filter media and the second filter media, wherein a path is defined for enabling the gas to flow from the gas inlet, through the first filter media, past the first collection basin, through the second filter media, and to the gas outlet, and wherein droplets of liquid collected by the second filter media may fall via gravity into the second collection basin. 2. The apparatus of claim 1 , wherein the second collection basin is defined by the housing, separate from the first collection basin. 3. The apparatus of claim 1 , wherein the first filter media is a coalescing media. 4. The apparatus of claim 3 , wherein the second filter media is a hydrophobic media. 5. The apparatus of claim 1 , wherein the second filter media is a hydrophobic media. 6. The apparatus of claim 1 , wherein the first filter media and the second filter media are both mounted, respectively, to the housing. 7. The apparatus of claim 1 , wherein the first filter media is configured so that droplets of liquid collected by the first filter media may fall via gravity into the first collection basin. 8. The apparatus of claim 7 , wherein the second filter media is configured so that droplets of liquid collected by the second filter media may fall via gravity into the first collection basin. 9. The apparatus of claim 1 , wherein the second filter media is configured so that droplets of liquid collected by the second filter media may fall via gravity into the first collection basin.
