An apparatus for treating air having a housing with a passageway extending therethrough for interconnecting a source of the air and a space to be conditioned; two air movers mounted in the housing for creating two reduced pressure zones internally of the chamber; a pivotally positionable damper mounted in the passageway for selectively directing air received from the source along predetermined paths of travel internally of the chamber; and a counter-flow heat exchanger and cooling pad mounted in predetermined positions in the path of travel extending to the space to be conditioned to absorb heat energy and evaporatively cool the air passing to the space to be conditioned.
