Abstract
Air enters the contamination control breather through openings in the top cap of the breather. Air then passes through air channels in the top cap. Dust particles are filtered by a filter assembly near the top of the breather, which also diffuses the air. The diffused air then passes through material which removes moisture, other gases, and liquids from the air. The air is then passed through another filtration layer to remove the desiccant particles from the air. The clean and dry air ultimately passes to a container or machinery, that uses filtered air, through an aperture in the bottom cap of the breather. The bottom cap can be permanently attached to the container so that only the elongated body and the filter assemblies need to be replaced when the desiccant reaches its maximum adsorption capacity.
Claims16
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- wherein said aperture in said first cap connects to a neck, said neck being air impermeably attached to a container that uses filtered air;
- and
- wherein said first cap further comprises a metal plate with an aperture therethrough, for reinforcing said first cap, wherein said aperture of said metal plate is collocated with said aperture of said first cap.
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- and
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- wherein said first cap further comprises a rim that is threaded on an inside surface.
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- and
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- wherein said second cap comprises
- a rim;
- and
- at least one ridge located along an inside of said rim, wherein said at least one ridge has a plurality of openings to facilitate air to pass through.
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- wherein said aperture in said first cap connects to a neck, said neck being air impermeably attached to a container that uses filtered air;
- and
- wherein said first cap further comprises a metal plate with an aperture therethrough, for reinforcing said first cap, wherein said metal plate is secured to a lower inside surface of said first cap.
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- and
- a filter cloth having a first side that is knitted differently from a second side, such that the filter cloth allows particles to pass through in one direction, but does not allow said particles to pass through in an opposite direction, wherein said filter cloth is positioned across an internal cross-section of the elongated body proximal to the first end.
A contamination control breather that processes unfiltered air into filtered air, the breather comprising:
- an air impervious elongated body open at a first distal end of the body and a second distal end of the body;
- a first cap attached to said first end for allowing the filtered air to exit the elongated body through an aperture in said first cap;
- a second cap attached to said second end for allowing the unfiltered air to enter said elongated body to pass through said elongated body to said first cap;
- and
- a filter assembly that is attached inside the body proximal to the second end, and said filter assembly seals tightly against the inside of the elongated body, thereby preventing air from bypassing said filter assembly;
- wherein said filter assembly comprises a wiper ring having an edge on a peripheral portion.
