Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator. The powder falls into a transfer pan and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver. The powder is then discharged to the feed hopper in the feed center. The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line cleaned by one or more cleaning elements drawn through the vacuum line.

Powder coating system with improved overspray collection

A system and related methods for configuring and monitoring a material application system for installation and use at a site that is remotely located from the material application system manufacturing site. The system provides a configuration module that allows a customer or purchaser to configure a system electronically based on the customer's spraying needs. The selected configuration may further be linked to a pricing and inventory database module to allow the customer to order the system components, and obtain price and delivery schedules. The configuration module is available to the customer via a secure web site over the Internet provided by a server accessed from a computer such as a personal computer. The system also provides an extranet, for example, via the Internet or other communication link, is used to provide an accessible database for historical data and configuration/installation information.

Apparatus and method for configuring, installing and monitoring spray coating application systems

A powder spray booth includes a booth canopy wall arrangement to contain powder during a spraying operation; and a booth floor that is rotatable relative to the booth wall during a spraying operation. The floor can be rotated about an axis that is also the longitudinal axis of the spray booth. The booth may be generally cylindrical in shape with a round floor. The booth canopy and top are supported on a base frame separately from the floor. By this arrangement, the floor can be rotated relative to the booth canopy. A powder extraction apparatus in the form of a low pressure duct suspended off the floor draws up powder that has collected on the floor. The extraction duct is stationary with respect to the rotating floor during a spraying operation. The floor may also be translated along the axis of rotation between a first position in which the floor can rotate and a second position in which the floor is sealed against a lower edge of the booth canopy wall. The booth canopy and floor are made of composite materials that are very low in conductivity to minimize powder adhering to the floor and booth walls. The booth is thus easy to clean with a substantially shorter time period required for color change.
