Abstract: A filtering media member is formed of porous material. A first edge portion includes an upstream edge. A second edge portion is spaced apart from the first edge portion and includes a downstream edge. A main portion is arranged intermediate the first and second edge portions. The edge portions and the main portion together define a generally planar first surface. A plurality of channels is formed on the first surface. Each of the channels is arranged adjacent to one another and has a length. Each of the channels includes an inlet disposed proximate to the first edge portion so that, in use, fluid flows from the upstream edge through the inlet to the respective channel, and each of the channels has a width in the lateral direction that decreases across its length so that the channels taper between the first and second edge portions.

Abstract: A filtration apparatus for filtering a fluid stream includes a vessel housing. At least one cartridge assembly is arranged within the vessel housing. The cartridge assembly includes filtration material arranged between at least one inlet and at least one outlet. The filtration material treats the fluid stream to form a filtered fluid stream. In use, the fluid stream is received a feed port of the vessel housing, flows through the filtration material in the cartridge assembly between the inlet and the outlet, and the filtered fluid stream is discharged from a discharge port of the vessel housing. The filtration apparatus can be used to remove siloxanes from the fluid stream.

Abstract: A silencer and catalytic converter apparatus includes a housing and a frame assembly arranged in the housing. The frame assembly may receive at least one catalyst panel and support the catalyst panel to occupy an area of a flow passage between upstream and downstream chamber sections of the housing. A blocking panel may be supported by the frame assembly to obstruct a remaining area of the flow passage so that fluid flowing between the upstream and downstream chamber sections is directed to flow through the catalyst panel. The blocking panel may be adjustable to accommodate catalyst panels of different sizes.

Abstract: A catalytic converter apparatus includes a housing having an inlet port, an outlet port, a chamber, an access opening, and an interior sealing surface generally encompassing a periphery of one of the inlet and outlet ports in the chamber. A substrate assembly is insertable into the chamber and removable from the chamber through the access opening, and includes a catalyst matrix for treating fluid. A positioning mechanism removably supports the substrate assembly within the chamber so that movement of the substrate assembly in a lateral direction generally parallel to the interior sealing surface moves the substrate assembly in an axial direction generally perpendicular to the interior sealing surface. The positioning mechanism may guide the substrate assembly in the axial direction into sealing engagement with the one of the inlet and outlet ports to provide a fluid flow path through the catalyst matrix between the inlet and outlet ports.

Abstract: A catalyst substrate support is provided for a corrugated foil honeycomb matrix defining a plurality of passages extending therethrough which are generally parallel to an axis. A peripheral mantle extends about an outer perimeter of the matrix and has inwardly extending flanges which extend across an outer periphery of the opposite end faces to cover outermost of the passages and restrict fluid flow between the peripheral mantle and the matrix. The outer perimeter of the matrix and the peripheral mantle may be spaced apart to define a gap for accommodating differential thermal expansions of the matrix and the peripheral mantle, the gap being smaller than a height of the inwardly extending flanges. Cross members secured to each of the opposite end faces of the matrix may transfer at least part of the gravitational load of the matrix to the mantle.

Abstract: According to the present invention a catalyst substrate is provided with a peripheral mantle extending thereabout and having opposite end walls between which the substrate is disposed. At least one of the end walls acts as a forward seal which is maintained in close proximity with a corresponding sealing surface toward an inlet end of the catalytic converter housing. A retaining member is provided which maintains the sealing surfaces In close proximity to define a labyrinth seal therebetween.
