A powder facility used for spray coating includes at least one injection unit ( ), at least two powder stations ( ) and at least one cleaning unit ( ) which are mutually displaceably in program-controlled manner in order to alternatively convey powder from one of the powder receptacles of the powder stations or to clean the powder-flow itineraries using compressed cleaning air.

Powder facility for spray-coating purposes

A spray booth for use in the spray coating of articles with coating powder. The spray booth forms a coating space which at a bottom is bounded by powder collection means. The powder collection means is divided into an inner collection means and a surrounding outer collection means for the separate collection of surplus powder and the separate removal of the entire surplus powder from the booth. The outer collection means collects surplus coating powder dropping off the inside surfaces of the booth walls. Since this powder may be contaminated with different color or different types of powder from previous spraying operations, it is discarded as waste. The inner collection means collects pure surplus powder which has not touched the booth wall surfaces. This pure surplus powder is recycled.
