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.

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.

A mixing and dispensing head is designed for use in a two component foam system. The head includes a body having a mixing chamber formed therein along a longitudinal axis and having a dispensing channel downstream of the mixing chamber. At least two supply portions are connected to the body, with each of the supply portions for supplying one of the components to the mixing chamber at a component entry location. Each of the component entry locations is longitudinally offset from each other. A rotating mixing member within the mixing chamber for mixing the components together to form the foam product. The mixing member includes a cylindrical core having indentations in the core and having angled vanes extending from the core. A shutoff portion is provided for stopping the flow of product from the dispensing channel.
