    • A spray booth for applying a coating to a substrate includes an outer chamber (12) containing a fluid therein having a predetermined first temperature and/or humidity and an inner chamber (14) in fluid communication with the outer chamber (12). The inner chamber (14) contains the fluid therein at a higher predetermined second humidity and/or temperature. The inner chamber (14) includes a fan (42) for recirculating a flow of the fluid at the second predetermined temperature and/or humidity therethrough and filters (34,36,44,46) for removing airborne comtaminants. A temperature and/or humidity control device (58) exhausts a predetermined amount of the fluid from the inner chamber (14) out of the inner (14) and outer chambers (12) said exhausted fluid being essentially free of toxic contaminants, the exhaust of the fluid drawing fluid from the outer chamber (22) into the inner chamber (14) to lower the temperature and/or humidity in the inner chamber (14).
    • 用于将涂层施加到基底上的喷涂室包括在其中容纳预定的第一温度和/或湿度的流体的外部腔室(12)和与外部腔室(12)流体连通的内部腔室(14)。 内室(14)在更高的预定的第二湿度和/或温度下容纳流体。 内室(14)包括用于使第二预定温度和/或湿度下的流体流再循环的风扇(42),以及用于去除空气传播的污染物的过滤器(34,36,44,46)。 温度和/或湿度控制装置(58)将来自内室(14)的预定量的流体从内部(14)和外室(12)排出,所述排出的流体基本上没有有毒污染物,排气 的流体引导流体从外室(22)进入内室(14)以降低内室(14)中的温度和/或湿度。
