A spray booth includes an outer enclosure in which the temperature and humidity of a fluid (such as air) is not controlled and a fluid handling unit within this enclosure, which circulates and controls the temperature and humidity of a smaller volume of the same fluid (air) to develop an environment suitable for application of coatings to desired substrates. In use, fluid is drawn from the outer enclosure into the inner, fluid handling unit in order to clean and modify the temperature and humidity of the fluid being handled, conditioning it to be delivered to the region of limited size which is established for receiving the substrate to be coated.

[ What is claimed is:] [1.] A spray booth for applying a coating to a substrate, the spray booth comprising:a fluid handling unit adapted to be positioned within an enclosure containing a fluid that is unregulated in humidity relative to the humidity of fluid outside of the enclosure, the fluid handling unit defining an open region between an outlet and an inlet of the fluid handling unit, the open region being open on at least one side to the enclosure to allow fluid to flow freely between the open region and the enclosure, wherein the fluid handling unit includes a housing extending from the outlet which draws fluid from the open region to the inlet which delivers fluid to the open region, and wherein the housing includes;a fan which causes circulation of the fluid from the outlet to the inlet,a filter in line with the flow of fluid through the housing, wherein the filter cleans the fluid passing through the fluid handling unit,a humidifier adapted to increase the humidity of fluid passing through the housing, anda dehumidifier adapted to decrease the humidity of fluid passing through the housing and recirculate the dehumidified fluid into the open region of the fluid handling unit via the inlet;wherein the open region is sized to receive at least a portion of the substrate so that the portion of the substrate is maintained within a curtain of the fluid extending between the inlet and the outlet having a humidity regulated so that the coating can be effectively applied to the substrate while positioned within the open region.
