Oil coalescing device

1. An external oil coalescing adapter configured to fit to a desiccant breather, the adapter comprising:

an adapter housing with a coalescing chamber for receiving an air flow containing oil;

a first end for receiving the air flow containing oil into the coalescing chamber, the first end having a single flow passage configured to receive both air flow and coalesced oil via the air flow containing oil;

a second end located at an opposite side of the external oil coalescing adapter from the first end, the second end parallel to the first end, the second end configured for emitting air from the coalescing chamber; and

a honeycomb material having a plurality of openings for coalescing oil contained in the air flow and positioned between the first end and the second end configured such that coalesced oil accumulates towards the first end, wherein the plurality of openings are sufficiently large to allow coalesced oil to fall into the first end under a force provided by gravity, the first end configured to both provide the air flow containing oil into the coalescing chamber and to receive the coalesced oil.

2. The adapter of claim 1 wherein the honeycomb material comprises a plurality of layers with each layer including a plurality of openings with the openings of at least one layer offset from the openings of another layer.

3. The adapter of claim 1 further comprising:

a first end cap, including a first ring, configured to fit at least partially inside the adapter housing at the first end and a second end cap, including a second ring, configured to fit at least partially inside the adapter housing at the second end;

wherein the honeycomb material is held in place by the first ring and the second ring.

4. The adapter of claim 1 wherein the honeycomb material is formed from material chosen from plastics, polymers, metals, fibrous materials, ceramics, and combinations thereof.

5. The adapter of claim 1 wherein the openings of the honeycomb material are positioned to extend longitudinally from the first end to the second end.

6. The adapter of claim 3 wherein the adapter housing is substantially cylindrical in shape and includes an inner diameter defining the coalescing chamber; and wherein the honeycomb material is substantially cylindrical in shape and includes an outer diameter substantially equal to the inner diameter of the adapter housing.

7. The adapter of claim 6 wherein the adapter housing includes a threaded inner wall; and wherein the first end cap includes first end cap threads and second end cap includes second end cap threads; the first end cap threads and second end cap threads configured to attach to the threaded inner wall of the adapter housing.

8. The adapter of claim 3 further comprising pressure fits configured to join the first end cap and the second end cap to the adapter housing.

9. The adapter of claim 3 wherein the first end cap and second end cap are permanently affixed to the adapter housing.

10. An oil coalescing breather comprising:

a breather housing with a standpipe for receiving an air flow containing oil;

a first end for receiving the air flow containing oil into the standpipe, the first end having a single flow passage configured to receive both air flow and coalesced oil via the air flow containing oil;

a second end located at an opposite side of the standpipe from the first end, the second end parallel to the first end, the second end configured for emitting air from the standpipe; and

a honeycomb material for coalescing oil contained in the standpipe, the honeycomb material comprising a plurality of openings and positioned between the first end and the second end configured such that coalesced oil accumulates towards the first end, wherein the honeycomb material includes honeycomb layers, each layer of the honeycomb layers having a plurality of openings large enough to allow coalesced oil to fall into the first end under a force provided by gravity, the first end configured to both provide the air flow containing oil into the coalescing chamber and to receive the coalesced oil.

11. The breather of claim 10 wherein each layer comprises a plurality of openings offset from the openings of another layer.

12. The breather of claim 10 further comprising lock rings configured to hold the honeycomb material within the standpipe.

13. The breather of claim 10 wherein the honeycomb material is formed from material chosen from plastics, polymers, metals, fibrous materials, ceramics, and combinations thereof.

14. The breather of claim 10 wherein the standpipe is substantially cylindrical in shape and includes an inner diameter; and wherein the honeycomb material is substantially cylindrical and fit to the inner diameter of the standpipe.

15. The breather of claim 10 wherein each layer comprises a plurality of openings extending longitudinally from the first end to the second end.

16. The breather of claim 10 wherein each layer of the honeycomb layers are positioned in fluid series connection.

17. An oil coalescing breather comprising:

a breather housing with a standpipe for receiving an air flow containing oil;

a first end for receiving the air flow containing oil into the standpipe, the first end having a single flow passage configured to receive both air flow and coalesced oil via the air flow containing oil;

a second end located at an opposite side of the standpipe from the first end, the second end parallel to the first end, the second end configured for emitting air from the standpipe; and

a honeycomb material for coalescing oil contained in the standpipe, the honeycomb material comprising a plurality of openings and positioned between the first end and the second end such that coalesced oil may accumulate towards the first end, the honeycomb material comprising a plurality of layers of honeycomb material with each layer comprising a plurality of openings offset from the openings of another layer, each of the plurality of openings configured large enough to allow coalesced oil to fall into the first end under a force provided by gravity, the first end configured to both provide the air flow containing oil into the coalescing chamber and to receive the coalesced oil.
