Abstract
A cleaning device for use with an atomizer that applies paint to the surface of a component in a spray booth includes an external and internal surface in which a least a portion of one or more of the surfaces are coated with a conductive coating. This conductive coating comprises one or more fluoropolymers and may be static dissipative. The cleaning device further includes an exit port that has an aperture between about 2.54-7.62 cm located in the shroud of the device opposite the opening that receives the atomizer and near a bottom corner of the shroud. A kit used to retrofit existing paint spraying systems includes a fully assembled cleaning device and optionally, a regulator assembly capable of reducing the pressure of a cleaning fluid to about 80 psi. During installation, the regulator assembly is mounted external to the spray booth.
