The present invention is a nozzle assembly having a nozzle main body including an ejection material suction port and an ejection port which ejects the ejection material with the compressed air, and an air nozzle which jets the compressed air into the nozzle main body. The nozzle main body includes a mixing chamber which mixes the ejection material with the compressed air, a first pathway directed from the ejection material suction port toward the mixing chamber, and a second pathway directed from the mixing chamber toward the ejection port. The air nozzle includes a compressed air jet portion and a third pathway directed to the compressed air jet portion, and the third pathway is inserted into the nozzle main body. The compressed air jet portion of the air nozzle is provided with a flow contracting portion having an opening.

A robotic system is provided for repeatedly and reproducibly applying a sealant to a seam in an assembled HVAC duct component. The applied sealant has a predetermined location on the assembled HVAC duct component to seal the seam. An assembled HVAC duct component is thus provided having a robot applied sealant on at least one seam in the assembled HVAC duct component, wherein the applied sealant has at least one of a predetermined location, thickness or coverage. The robotically applied sealant can be applied to a blank for forming the assembled HVAC duct component, wherein the sealant is located at locations forming a seam in the assembled HVAC duct component.

The objective of this invention is to provide a filter module for coating equipment that can improve the efficiency in removing coating-material mist and preventing the outflow of such coating-material mist to the outside. The filter module of this invention is made of a flammable material and includes an outer box, an eliminator and a baffle plate. Of the outer box, the air A2 containing the coating-material mist flows into the outer box from the outer-box inlet and is discharged from the outer-box outlet. The eliminator is formed by arranging zigzag-shaped eliminator elements in parallel to separate the coating-material mist from the air A2. The baffle plate is formed by arranging baffle-plate elements having an inclined surface for guiding the air A2 in parallel into the inflow-side space S2 of the eliminator, and guides the air A2 that has been introduced from the outer-box inlet to the inflow-side space S2.

A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is in fluid communication with a fluidizing pressure source. The extraction duct is in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.

The powder coating system according to the invention for coating workpieces with coating powder has a coating cubicle (3) and a cyclone separator (5), the coating cubicle (3) being connected to the cyclone separator (5) via a residual powder pipe (4). The cyclone separator (5) comprises in its inlet region an outlet tube (23) in which there is disposed a guide apparatus (50) that has multiple blades (51). These are designed so that the air vortex (28) impinging on the blades (51) can be deflected into a vertical air stream (30).

A cyclone is disclosed that includes an enclosure that encloses at least a portion of the cyclone. The enclosure delimits an enclosed volume between an interior surface of the enclosure and the exterior surface of the body. The enclosure retains a gas coolant or liquid coolant in thermal exchange with the enclosed exterior surface of the cyclone. A powder coating system is disclosed that includes a spray booth and a cyclone, where ambient air is added to process air that is drawn from the spray booth into the cyclone. The ambient air may be added to the process air to cool the process air to a temperature that is lower than the process air would be if ambient air were not added, and also may be used to dilute the powder overspray entrained process air.
