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: establishing a first radially facing seal interface radially between the first and second fluid flows via a 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, the anti-prefill device having a tubular wall and a cap portion spaced axially from the tubular wall and disposed over the opening of the central interior space, wherein the first fluid flow is directed to the base via the cap portion, such that the fluid flows axially through the tubular wall and thereafter radially around the cap portion.
