Abstract
An air washer comprises upper and lower plenum chambers which are separated by a panel which carries tubes. A spray nozzle above each tube is oriented to direct the conical spray it forms into the tube to wet the lower half of the bore of the tube. An inlet duct communicates with the lower plenum chamber. A tank is provided below the lower plenum chamber. Filter apparatus is provided in the tank. A fan communicates with the upper plenum chamber and draws air from the inlet duct via the plenum chambers and the parallel paths through the tubes. The air is washed by the spray formed by the nozzles which are fed with liquid drawn from the tank through the filter apparatus.
