Abstract: A paint system including at least one spray gun located, a paint line changing assembly and a plurality of differently colored paint sources. The paint line changing assembly is configured to selectively connect the at least one spray gun with one of the plurality of differently colored paint sources. The paint system further includes a controller for maintaining at least one of the plurality of differently colored paint sources in a partially fluidized state when not connected to the at least one spray gun and for maintaining the one of the plurality of differently colored paint sources in an operative fluidized state when connected to the at least one spray gun.

Abstract: A system for monitoring the emission of VOCs in a workstation is disclosed including a sensor to obtain a signal representative of the amount of coating discharged in the workstation, a database for storing data values representative of the signal, a network configured for allowing access to the database and at least one computing device for access to the database over the network and providing a user interface for presenting information representative of at least a portion of the data values. A method for monitoring the emission of VOCs in a workstation is disclosed.

Abstract: A method includes providing a paint system having a plurality of supply tanks that can be selected for supplying powder paint to a spray site, each having a supply line connected to the supply tank and having an end section, a spray gun, and a purge air supply. Each end section is configured for selective connection to the spray gun to spray powder paint from the supply tank and also for connection to the purge air supply to blow residue powder paint in the supply line back into the supply tank. A control device operably connects a fluidizing air supply to each supply tank. The control device is configured to fluidize the powder paint in each tank at a low standby pressure when the supply tank is not in use, and to fluidize the powder paint in the tank at a higher operating pressure when the supply tank is selected for use. Methods related to the above cause the color change to be very efficient and quick, with low waste of powder paint.
