A method for operating a surface treatment plant, resulting overspray in a coating booth is taken up by an air flow. The air flow loaded with overspray is conveyed as exhaust air flow to at least one separation unit in which overspray is separated out. In a supply region upstream of the at least one separation unit and/or in an internal space of the at least one separation unit, a filter aid having a separation aggregate state is added to the exhaust air flow and forms, with the overspray, a separation mixture which is separated in or at the at least one separation unit. The filter aid used is solid or liquid in the separation aggregate state. In the at least one separation unit, conditions are established in which the filter aid transitions from the separation aggregate state into a gaseous aggregate state such that the gaseous filter air can separate from the separation mixture.

A particulate spray booth having a sealed particulate spray device booth wall opening is disclosed. The powder coating material spray system may include a booth comprising a ceiling, a floor, and side walls defining an interior of the booth, wherein the booth defines an opening from the interior of the booth to an exterior of the booth. The system may further include a powder spray device received through the opening, the powder spray device comprising a body and a nozzle through which powder coating material is sprayed into the interior of the booth, wherein the nozzle and at least part of the body are disposed in the interior of the booth. The system may further include a flexible boot element having a proximal end and a distal end opposite the proximal end, the proximal end attached to a periphery of the opening to form a first seal and the distal end attached to the at least part of the body of the powder spray device disposed in the interior of the booth to form a second seal.

A lotion application machine for allowing automatic application of a lotion to the body of a user is provided. The lotion application machine has a rotatable platform, on which the user can stand and be rotated while the lotion is being applied. The lotion can be applied evenly to the entire body of the user.

In a method for operating a surface treatment installation, overspray produced in a coating booth is taken up by an air stream and carried to one or more one-way filter modules, in which overspray is separated. Once a limit loading with overspray is reached, a one-way filter module is exchanged for an empty one-way filter module. Depending on the nature and characteristics of the overspray, the one or more one-way filter module(s) may be chosen from a set of different one-way filter modules. A set of filter modules for use in a surface treatment installation is provided having various filter modules formed as exchangeable one-way structural units with a module housing and a filter unit. The module housings of the various filter modules have the same-connection module inlets and the same-connection module outlets and at least the filter units of two different filter modules are formed differently.

A workpiece processing arrangement comprises a spray booth (2) defining a work space (21), and operable to provide a controlled environment for spraying of material, a first oven (4) located adjacent a first end of the spray booth, the first oven defining an internal zone, and a second oven (5) located adjacent a second end of the spray booth, the second oven defining an internal zone (51). The arrangement also includes a transport rail (6) which extends from the internal zone (41) of the first oven (4), through the work space (21) of the spray booth (2) into the internal zone (51) of the second oven (5), the transport rail (6) being adapted for transport of a workpiece (10) between the work space (21) of the spray booth (2) to the internal zone of the first or second oven (4, 5). A corresponding method of processing a work piece in such an arrangement indicates the steps to be used when processing a first and a second workpiece The ovens may have both a baking and a curing zone. A ventilation system with an air curtain (23) may be included.

An electrical field is generated between an application device and an object to be coated. At least one corona electrode associated with the application device is connected to ground, and at least one counter electrode associated with the object is connected at least at intervals to a positive potential. A system for electrostatically coating objects having an application device coating material, and an electrical field device having a high-voltage source which generates an electrical field between the application device and an object to be coated. The field device comprises at least one corona electrode associated with the application device, and at least one counter electrode associated with the object, wherein, during the operation of the device, the at least one corona electrode is connected to ground, and the at least one counter electrode is connected at least at intervals to a positive potential.

The disclosure provides a multi-function ductless enclosure apparatus. Its main purpose is to be used as a paint spray booth to capture excess paint, pass it through filters with the use of a fan and then exhaust the ensuing clean air out, back into the room air. This booth is foldable and light weight and can be moved to a different location in minutes. It can also be transformed to serve many other applications with the use of a few accessories thereby saving the end user from having to have several booths (saving counter space) and also saving him from having to spend a lot of money buying many booths for different applications.

A recirculating powder applicator includes an applicator body having an inlet on an upstream surface and an outlet on a downstream surface, wherein the inlet and outlet define a passage that extends transversely through the thickness of the applicator body, a powder conduit, an air inlet, an exhaust aperture located on one of the upstream or downstream surfaces, and a circulation chamber located on the interior of the applicator body. The powder conduit and air inlet are in fluid communication with the passage and the passage is in fluid communication with the circulation chamber. A method of applying powder to a substrate during a continuous process includes using a recirculating powder applicator.

A transportable vehicle enclosure for painting vehicles includes side, front, rear, ceiling and floor portions, one of the portions being configured to allow vehicular access. In use, a vehicle may be placed within the enclosure. The enclosure further includes an air handling unit for respectively producing a first temperature level within the enclosure suitable for a spray mode of operation and a second temperature level within the enclosure suitable for a baking mode of operation.

A transportable body (10) suitable for spraying vehicles comprising a main body having a spray compartment (12) with a floor, a ceiling, opposed side walls (16, 18), and a vehicle entry door (20) an upper air inlet plenum for introducing air through the ceiling and an air exhaust in the floor wherein the air inlet and air exhaust are configured to provide a downdraft ventilation system the opposed side walls of the spray compartment are outwardly moveable from a transport position in which the main body can be loaded onto a transporter and a spray position a utility compartment (14) housing an air inlet handling unit (24) with an air inlet fan for supplying air to the air inlet and an air exhaust handling unit (26) with an air exhaust fan for drawing exhaust air from the air exhaust in the floor, the compartments being arranged end to end and a wall separating the compartments.
