Abstract
A contaminate control device for filtering contaminates from a gas such as air is provided. The device includes a housing having a first inlet and a first outlet. An axial flow filter is fluidly coupled between the first inlet and the first outlet, the axial flow filter has a second inlet and a second outlet. A second filter disposed about the axial flow filter and is fluidly coupled between the first inlet and the first outlet, the second filter having a third inlet on an inner diameter and a third outlet disposed on an outer diameter. A flow restrictor is fluidly coupled between the second inlet and the first inlet.
Claims20
A contaminate control device comprising:
- a housing having a first inlet and a first outlet;
- an axial flow filter fluidly coupled between the first inlet and the first outlet, the axial flow filter having a second inlet and a second outlet;
- a radial flow filter disposed about the axial flow filter and fluidly coupled between the first inlet and the first outlet, the radial flow filter having a third inlet on an inner diameter and a third outlet disposed on an outer diameter;
- and,
- a flow restrictor fluidly coupled between the second inlet and the first inlet.
A contaminate control device comprising:
- a housing having an inlet on a first end and an opening on a second end;
- a first cover sealingly coupled to the opening, the first cover and the housing cooperating to define an interior volume, the first cover having an outlet;
- and,
- a filter member disposed within the interior volume and fluidly coupled between the inlet and the outlet, the filter member having a cylindrical filter portion arranged to receive gas directly from the inlet and configured to filter an axial flow and a tubular filter portion at least partially disposed about the cylindrical filter portion, the tubular filter portion arranged to receive a gas from the inlet and filter a radial flow, the filter member having a flow restrictor disposed between the cylindrical filter portion and the inlet.
A contaminate control device comprising:
- a pressure vessel having a closed first end and an open second end, the first end having a wall having an inlet and a first chamber;
- a first cover removably and sealably coupled to the second end, the first cover having an outlet, the pressure vessel and the first cover cooperating to define an interior volume;
- a member removably coupled within the interior volume, the member comprising:
- an axial flow first filter having a housing and a perforated inlet end and a perforated outlet end, the first filter having a catalyst disposed therein, wherein the perforated inlet end is fluidly coupled to the first chamber and the perforated outlet end is fluidly coupled to the outlet;
- a flow restrictor disposed in the housing adjacent between the perforated inlet end and the first chamber;
- a radial flow second filter having an inner diameter and an outer diameter, the second filter being disposed at least partially around the first filter;
- a first channel defined by the housing and the inner diameter, the first channel being fluidly coupled to the inlet;
- and,
- a second channel defined by the pressure vessel and the outer diameter, the second channel being fluidly coupled to the outlet.
