A spray booth for providing a controlled environment for spraying of material comprises a roof portion (31), a side portion which extends from the roof portion to a floor, first and second end portions which extend from respective opposing ends of the roof portion to the floor, the roof portion, side portion and first and second end portions thereby defining a work space (21) having a substantially closed side, a pair of substantially closed ends, and a substantially open side, air input equipment (34) operable to provide an input airflow into the work space via the roof portion (31), and air extraction equipment (32,37,38,33) operable to produce an output airflow to extract air from the work space. In use, the volume flow rate of the input airflow is larger than the volume flow rate of the output airflow, creating an outpour of excess oof input air acting as an air curtain (23) on the open side. |
