ABSTRACT:
An inverse flow depth filter assembly includes an elongated, generally elliptical housing with gas inlet and egress means, and a bottom drain. A filter cartridge is suspended from the housing top so that an annular channel is created between the housing and the cartridge. The cartridge has passages at the top, leading to the egress means and an open bottom. Air enters the housing and is channeled downward through the annular channel until it reaches the cartridge bottom, quiets the turns upwardly through the filter. Heat exchange apparatus cools the down-flowing air and promotes condensation of the water. The heat exchange apparatus can include a plurality of fins fixed to the exterior of the housing to promote heat exchange with the surrounding atmosphere. Heat exchange fins disposed internally at the annular channel promote heat exchange between the flowing air and the housing. The fins increase the contact surface area for better heat exchange with the outside air. The at least one, preferably helical fin extends partway into the annular channel, improving surface contact without substantialy resistance to air flow.
