Abstract: A humidifier comprises a conduit (20), a rotatable fan assembly (30) mounted in the conduit (20) for causing an air stream to flow through the conduit (20), and a counter-rotatable water slinger assembly (40) mounted coaxially with and downstream of the fan assembly (30) for centrifugally ejecting water into the conduit (20). A cylindrical mist-forming member (60) affixed to the fan assembly (30) for rotation therewith extends downstream therefrom so as to surround the water slinger assembly (40). Water ejected centrifugally from the water slinger assembly (40) is sheared by the mist-forming member (60) into a mist of fine water droplets, which become entrained in the air stream passing through the conduit (20).

Abstract: A duct system for distributing humidified air from a humidifier has a duct and an eliminator sheet assembly mounted at an outlet of the duct. The eliminator sheet assembly includes eliminator sheets movably mounted in the outlet of the duct, and means for securing the eliminator sheets in a plurality of positions so that the direction of air discharged from the outlet can be changed. A structural member for mounting the eliminator sheet assembly at the duct includes a track defined by sidewalls, one of which sidewalls extends upward of the other to capture droplets emitted from the eliminator sheet assembly, and a drain plate assembly for catching condensation falling from the duct. The drain plate assembly includes an elongated trough for attachment to the duct, the trough having two sidewalls and a flexible partition. The partition has an inverted V-shaped cross section and divides the trough into two compartments extending side-by-side.

Abstract: A humidification apparatus including a housing, a fan assembly mounted in the housing and having conduits extending therein, a slinger assembly rotatably mounted in the housing adjacent to and coaxial with the fan assembly and having vanes on a surface thereof, and water feed means for delivering water through the conduits in the fan assembly to the surface of the slinger assembly.
