Abstract

Solutions for improving efficiency of a filter device for use with a machine requiring clean airflow are disclosed. In one embodiment, the filter device includes: a filter housing about an airflow inlet of the machine, wherein the filter housing comprises an air-permeable filter media configured to filter particles from multi-directional airflow moving through a substantial portion of the filter housing into the airflow inlet.

Claims (23)

1. A filter device for use with a machine, the filter device comprising:

a filter housing about an airflow inlet of the machine, wherein the filter housing substantially comprises an air-permeable filter media configured to filter particles from a multidirectional airflow moving through a substantial portion of the filter housing into the airflow inlet, wherein a portion of the filter housing directly contacts a ground surface.

2. The filter device of claim 1 , wherein the filter housing has a substantially semi-spherical shape.

3. The filter device of claim 1 , wherein the filter housing has a substantially geodesic dome shape.

4. The filter device of claim 1 , wherein the filter housing is flexible.

5. The filter device of claim 1 , further comprising a vibration device for vibrating the filter device and removing particles on the air-permeable filter media.

6. The filter device of claim 1 , wherein the air-permeable filter media includes at least one of: a glass-fiber material or a polymer-synthetic material.

7. The filter device of claim 1 , wherein the air-permeable filter media includes a hydrophobic membrane material.

8. The filter device of claim 1 , wherein the air-permeable filter media further includes a hydrophobic coating.

9. The filter device of claim 1 , wherein the air-permeable filter media includes a multi-layered fabric.

10. A machine, the machine comprising:

an airflow inlet; and

a filter housing about the airflow inlet of the machine, wherein the filter housing substantially comprises an air-permeable filter media configured to filter particles from a multidirectional airflow moving through a substantial portion of the filter housing into the airflow inlet, wherein a portion of the filter housing directly contacts a ground surface.

11. The machine of claim 10 , wherein the filter housing has a substantially semi-spherical shape.

12. The machine of claim 10 , wherein the filter housing has a substantially geodesic dome shape.

13. The machine of claim 10 , wherein the filter housing is flexible.

14. The machine of claim 10 , further including a vibration device for vibrating the filter housing and removing particles on the air-permeable filter media.

15. The machine of claim 10 , wherein the air-permeable filter media includes at least one of: a glass-fiber material and a polymer-synthetic material.

16. The machine of claim 10 , wherein the air-permeable filter media includes a hydrophobic membrane material.

17. The machine of claim 10 , wherein the air-permeable filter media further includes a hydrophobic coating.

18. The machine of claim 10 , wherein the air-permeable filter media includes a multi-layered fabric.

19. The filter device of claim 1 , wherein the portion of the filter housing includes supporting structures for directly contacting the ground surface.

20. The machine of claim 10 , wherein the portion of the filter housing includes supporting structures for directly contacting the ground surface.
