A painting booth includes a pair of first inner surfaces facing each other in a first horizontal direction with a painting treatment area therebetween and a pair of first inclined ceiling surfaces inclined downward from a position close to a center, in the first horizontal direction, in an upper part of the inside to an upper end part of each of the pair of first inner surfaces. An air supply duct is disposed at a center of the upper part of the inside, and a side air blow-out port is provided on the air supply duct to blow air against the pair of first inclined ceiling surfaces.

A coater includes a chuck, a source of a coating material, a dispensing head, an exhaust system, and a liner. The chuck is configured to support a wafer. The dispensing head is configured to dispense the coating material onto the wafer. The exhaust system is configured to exhaust the excess coating material. The liner is present at least partially on an inner surface of the exhaust system. The liner has a stick resistance to the coating material, and the stick resistance of the liner is greater than a stick resistance of the inner surface of the exhaust system.

A device for the application of a liquid fluid to a peripheral area of a lid using pistols for injecting said liquid fluid. The device includes an articulated mechanical device combined with at least two coaxial tubular shafts: a main supply shaft and a lower shaft, where a lower end of the main supply shaft connects to a first part of the articulated mechanical device, while a second part of the articulated mechanical device connects to a lower end of the lower shaft. The two coaxial tubular shafts rotate independently by means of transmission devices. The main supply shaft is arranged in an inner hole of the lower shaft, which is arranged coaxially around at least one section of the main supply shaft.

A cyclone comprises a second or lower portion that is pivotable with respect to a first or upper portion about an articulation between a first position and a second position; the second portion being aligned with the first portion along a first or vertical axis when the second portion is in the first position, and the second portion being aligned on a second axis that is different from the first axis when the second portion is moved from the first position to the second position. In various additional embodiments, the second axis may be normal to the first axis, for example, in the first position the lower portion is horizontal and in the first position the lower portion is vertical and aligned with the upper portion. The second position may be used as a cleaning position. When the lower portion is pivoted away from the upper portion, the vortex is interrupted. In the second position, the lower portion may also interface with a suction mechanism.

An overspray spray capture structure integrated into a paint spray operation integrates at least one reception surface for receiving an overspray of the spray coating operation. The overspray is communicated through a merging location established between the receiving surfaces and adapted to being removed or recycled. The at least one reception surface further includes first and second oriented reception surfaces not limited to a pair of horizontal and vertical closed loop belt curtains which are traversable supported about a pair of spaced apart rotating shafts. The first and second reception surfaces can include traversing paper rolls for capturing the overspray therebetween at the merging location. Other variants include water curtain or vacuum removal assist assemblies for removing the overspray prior to it setting.

A modular tire spraying system includes a downdraft spray booth for receiving a tire, a fluid delivery system disposed in the spray booth, a robot for transporting the tire to the spray booth, and a platform on which each of the spray booth, the fluid delivery system, and the robot is disposed. The fluid delivery system includes at least one spray gun for delivering a coating to the tire.
