Abstract: The apparatus for coating systems comprises: a first feeding unit provided with first loading and unloading means of a first coating powder; a second feeding unit provided with second loading and unloading means of a second coating powder; a pump assembly associated with a spraying system for sending the first powder and the second powder into a coating booth; connecting means of the pump assembly to the first feeding unit and to the second feeding unit, variable between: a first configuration, in which the pump assembly is operatively connected to the first feeding unit for sending the first powder into the booth; and a second configuration, in which the pump assembly is operatively connected to the second feeding unit for sending the second powder into said booth.

Abstract: A powder coating booth having a bottom surface, defining an inner space in which is insertable an element to be coated. The powder coating booth having at least one spraying device adapted to spray coating powder on said element to be coated and at least one collecting area defined in said inner space, on top of which said element to be coated passes to be coated with coating powder and in which the excess powder falls down. The powder coating booth being associated with first suction device for sucking and conveying air exiting said inner space, wherein said collecting area is associated with second suction device adapted to suck and convey said excess powder exiting said inner space.
