Abstract: A portable fan with misting nozzles for providing a cooling mist to the air flow of a fan. The portable fan with misting nozzles includes a fan assembly adapted for creating an air flow. A water supply assembly for storing water. A plurality of nozzles adapted for spraying a mist of water into the air flow of the fan assembly. The nozzles are in fluid communication with the water supply assembly. The nozzles are coupled to the fan assembly.

Abstract: To maintain alignment of the lower ends of the multiple electrode panels of an electrostatic precipitator collector electrode, an alignment device is utilized having an elongated bar mounted adjacent its ends in aligned underlying relation with the bottom edges of the electrode panels which are suspended in lateral edge-to-edge, essential coplanar relation. The bar, in turn, mounts a distributed plurality of pairs of opposed wicket-shaped aligning elements in flanking relation with the lower end portion of each panel to resist lateral, swaying movement, while permitting the limited panel motion occurring during normal precipitator operation.
