A plenum chamber is formed in the first member. The plenum chamber is in fluid communication with and downstream of the plurality of filter passageways. A second set of channels is formed in the generally planar surface of the first member to form, in cooperation with the generally planar surface of the second member, a plurality of nozzle outlet passageways. These nozzle outlet passageways are in fluid communication with the plenum chamber. The nozzle outlet passageways include a plurality of nozzle outlets which are adapted to discharge a plurality of fluid jets that impinge on one another to thereby atomize a flow of fluid.
