Abstract:
1. A method of sealing a filter with respect to a base and sealingly separating a first fluid flow from a second fluid flow radially outward of the first fluid flow, the method comprising: engaging a first radially facing surface of the base with a first portion of a first seal member; establishing a first radially facing seal interface radially between the first and second fluid flows via the first portion of the first seal member; establishing a second radially facing seal interface radially outward of the second fluid flow via a second seal member; and directing the first fluid flow from a central interior space of the filter to the base via an anti-prefill device associated with an opening of the central interior space, wherein the anti-prefill device includes a plurality of wall portions establishing a radially facing wall including apertures, wherein the first fluid flow passes to the base via at least one aperture of the plurality of apertures, and wherein at least part of the first seal member is spaced a first axial distance from the filter and at least part of the second seal member is spaced a second axial distance from the filter, the first axial distance being greater than the second axial distance.
