A paint booth assembly includes a dry filtration system for filtering paint particles from a downdraft of air. The dry filtration system includes at least one filter module disposed in a paint filtration portion of a paint booth for receiving the downdraft of air. The filter module includes a plurality of filter drawers sequentially arranged relative to one another along a flow path of the downdraft of air, with each of the filter drawers slideable relative to a side wall between filtering and cleaning positions. In the filtering position, a disposable filter within the respective filter drawer is disposed within the paint filtration portion for filtering paint particles from the downdraft of process air. In the cleaning position, the respective filter drawer is slid out into an external environment of the paint booth for allowing the disposable filter to be removed and replaced by an operator.

A portable variable volume paint spray enclosure or booth includes a frame assembled from longitudinal members and detachable clamps. The clamps secure together adjacent ends of the longitudinal members. The paint spray enclosure further includes a flexible cover disposed upon the frame such that a relatively air tight enclosure having a predetermined configuration is formed. The assembled frame and flexible cover extends from grade level to a predetermined elevation to encase an object to be painted. The paint spray enclosure also includes an air flow input apparatus for allowing air flow into the enclosure, and an air extraction apparatus/air scrubber for removing air from the enclosure, such that air mixed with vaporized paint inside the enclosure is removed from the enclosure before the paint vapor and air combine to form an explosive mixture, thereby preventing an explosion and/or fire from occurring inside the enclosure, and preventing operators from being exposed to harmful fumes. The air scrubber removes the paint vapor from the air as the combination exits the enclosure, thereby allowing only “clean” air back into the atmosphere.

A powder conveying device for coating powder includes a powder conveyor having a powder outlet duct and a powder outlet valve for opening or for closing the powder outlet duct. Additionally, a setpoint value generator for specify a setpoint opening period of the powder outlet valve, and a sensor for determining the actual opening period of the powder outlet valve are provided. The powder conveying device furthermore includes an evaluation unit for determining the deviation between the setpoint opening period and the actual opening period.

In order to provide a filter system for separating off contaminants from a stream of untreated gas that contains contaminants that is of simple construction and is operable efficiently, it is proposed that the filter system should include the following: a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom, wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements.

A mobile automotive spray booth having a collapsible enclosure and a fire suppression system. The fire suppression system includes a control unit, a fire detection cable or cable assembly in communication with the control unit, and a fire extinguisher assembly in communication with the control unit. The fire detection cable or cable assembly extends across at least a portion of the collapsible enclosure, and is configured to detect a fire within the collapsible enclosure. The control unit is configured to activate the fire extinguisher assembly to extinguish the fire upon detection of the fire by the fire detection cable or cable assembly. The fire detection cable or cable assembly is configured to bend to allow the collapsible enclosure to collapse from an expanded configuration to a collapsed configuration without removal or disassembly of the fire detection cable or cable assembly.

The invention relates to a filter module for trapping overspray from booth air laden with overspray from coating facilities, particularly from painting facilities, having a module housing, in which a filter structure (88) is accommodated and which has a module inlet (74) and a module outlet (76), wherein the filter module (40) is designed in such a manner that it is swapped for an empty filter module (40) once a limit loading of overspray is reached. The filter module (40) comprises a recyclable reusable structure (112) of one or more reusable components that can be thermally regenerated and therefore the filter module (40) can at least partially be thermally regenerated. The invention also relates to a trap having one or more filter modules of this kind, a coating facility for coating objects (14) and to a method for operating a coating facility.
