Improve the efficiency of your paint gun with 3M PPS Paint Preparation System. These products eliminate the need for traditional mixing cups and filters. A disposable liner bag marries to a direct filter. These disposable parts are mounted on the spray gun by a cup and collar system and a dedicated adapter. Because the liner bag collapses, the spray gun will function at any angle. Liner bag and filter are disposable. That means easy cleanup and less harmful solvents. 3M PPS Paint Preparation System is therefore a cleaner, faster system, safe from outside contamination and offering considerable time and solvent savings on gun and parts
