ABSTRACT:
The present invention is a means and method for powder dusting various manufactured products such as extrusions, sheet materials, thin films, and piece parts. The powder dusting system includes a regenerative compressor which propels an air/dust mixture through a control valve body into a cone shaped filter where a majority of the air is filtered out. The remaining concentrated air/dust mixture enters a head component where head jets direct the air/dust mixture to the item that is being coated. The powder duster of the present invention also provides a method of coating manufactured products on both their interior and exterior surfaces.
