Powder collectors for the automatic collection and recycling of powders such as in a powder coating booth are disclosed. The collectors utilize a rollaway collection assembly having one or more cartridge filters therein so as to allow the quick change of vector assemblies on the coating booth for color change convenience. The cartridges themselves may also be readily changed as they preferably are not rigidly mounted to the collection assembly but instead merely sole positioned therein as to become functional upon turning on the air flow for the collection system. Continuous operation is provided by periodic blow-down of the cartridges with a fluidized bed providing automatic recycling (or disposal in the case of dust collection systems) of the collected powder. Various embodiments are disclosed including one embodiment utilizing envelope filters with an automatic blow-down provision.

A collector comprising: a housing defining a first chamber having means for coupling to an exhaust duct, said housing including support structure and having therein at least one velocity stack means disposed adjacent a first chamber intake opening in said housing, said housing also having high pressure means for controllably directing a blast of air through said at least one velocity stack means and out said first chamber intake opening; a collector assembly structurally independent of said housing and defining a second chamber having disposed therein at least one filter element which is structurally supported entirely by said collector assembly, said second chamber having a first opening for cooperating with a mating opening in a housing structure containing particulate laden air to be filtered, and at least one second opening adjacent said at least one filter element and cooperatively disposed with respect to said first chamber intake opening, so that air must pass through said at least one filter element to pass through said at least one second opening, said second chamber being mobile so as to be readily moveable with respect to said first chamber; and a manually operable means for coupling said collector assembly to said first chamber and simultaneously therewith sealingly engaging said at least one filter element with said at least one first chamber intake opening for communication with said at least one velocity stack means.
