A portable paint booth has a floor, roof and walls made of non-porous materials, at least one door, an air inlet adapted to receive air from a mechanical blower, and an exhaust tube that extends from the booth and comprises at least one orifice disposed at a terminal end of the tube, wherein the terminal end of the tube is disposed above a junction of a wall and the roof when the booth is pressurized. The exhaust tube may be supported by a pole to hold the tube upright and maintain a predetermined height. The terminal end of the tube may be propped open by a support element that extends around a perimeter of the exhaust tube.

A method for removing overspray from air flow exiting a painting booth may include passing the air flow through an incoherent mass of cleaning elements, which are kept in a stirred condition, so as to release the overspray onto the cleaning elements of the incoherent mass.

An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part (the AM part) is disclosed. The apparatus may include a chamber, a support surface within the chamber, and one or more nozzles within the chamber. The nozzles may be the same size or different sizes. The support surface may be configured to support the AM part. The support surface may have one or more openings sized and configured to allow the fluid to pass through the opening(s). The nozzles may be configured to spray a fluid at the AM part, and the spray may be an atomized or semi-atomized spray of the fluid.

Provided is a substrate processing apparatus. The substrate processing apparatus includes a swing nozzle that is arranged on one side of the support module, moves in a swing manner, and sprays a chemical solution to the substrate, a sensor arranged on one side of the swing nozzle to sense movement of the swing nozzle, an electromagnet and a magnet installed on the other side of the swing nozzle so as to be able to adjust spacing relative to each other, and a controller for receiving a sensing result of the sensor and performing a damping operation to the swing nozzle by providing power to the electromagnet to generate an attractive force or repulsive force between the electromagnet and the magnet.

A coating booth (101) for elements to be coated. The coating booth (101) comprises a passage between opposing vertical sides (107a, 107b, 108a, 108b) through which elements to be coated are conveyed. There is an entrance (105) at one end of the passage and an exit (106) at the other end of the passage. The coating booth (101) comprises a conveyor line (102) for supporting said elements to be coated and configured to convey said elements from the entrance (105) to the exit (106) along a straight pathway, and, a suction system. The opposing sides of the channel are symmetrical about the pathway. Sets of spray guns (103a, 104a, 103b, 104b) for spraying coating powder at the elements are positioned symmetrically either side of the straight pathway. The suction system comprises vertical suction inlets (109a, 109b) mounted opposite one another on each opposing vertical side of the passage, the suction system being configured to provide equal amounts of suction through each of the opposing vertical suction inlets (109a, 109b).

A painting booth may include: a painting chamber and/or an overspray removal unit. Paint may be sprayed in the painting chamber. The painting chamber may be crossed by an air flow for evacuation of overspray from the painting chamber. When exiting the chamber, the air flow may pass through the overspray removal unit in order to remove the overspray from the air flow. The overspray removal unit may include an incoherent mass of cleaning elements kept in a stirred condition, through which the air flow containing the overspray passes so as to release the overspray onto the cleaning elements. A method for removing overspray from air flow exiting a painting booth may include: passing the air flow through an incoherent mass of cleaning elements which are kept in a stirred condition, so as to release the overspray onto the cleaning elements of the incoherent mass.
