Abstract
A first and second housing is joined together by a middle housing rotatable with respect to the first and second housing. The first and second housings have conduits passing through exterior walls and an annular ring on an inside wall together with an annular interior edge rotatably joined to first and second side rim channels of the middle housing. A heat-moisture exchanger material having an annular opening through which a tube passes is mounted within the middle housing so that in a first rotatable position air and moisture passes through the first and second housing conduits directly and in a second rotatable position must pass through the heat-moisture exchange material.
