Since PPS™ uses the same cup for mixing and spraying, there less risk of outside contamination, less time spend mixing and cleaning. PPS™ is a complete painting system from 3M™ which produces cleaner jobs, saves on solvent usage and gun cleaning time and can improve operator efficiency by as much as 15%. Specifically designed adapters allow painters to use the PPS™ system with virtually any spray gun. br/br/PPS™ replaces traditional mixing cups and filters and drastically reduces the amount of solvent required for gun cleaning. The liner, lid and built-in filter are all disposable, leaving only the adapter and spray gun to be cleaned. It is possible to clean your paint gun with as little as 85 grams of solvent. With these disposable parts, shops can see a 70% savings in cleaning solvent use -- meaning less operator exposure to solvents and reduction in VOCs. With PPS™ your spray gun functions at any angle. Many painters mix more paint than they need to reduce the chance of starving the gun. PPS™ allows painters to spray at any angle without starving the paint gun.Kit contains 50 disposable lids with 125 micron filters, 50 disposable liners, and 20 sealing plugs. The 125 micron filters are recommended for water borne paint or primer applications.
