3M PPS 2. 0 Refill Kit keeps you stocked for using the PPS 2. 0 spray gun system, our all-in-one solution for measuring, mixing, filtering and spraying paint materials. Our latest and greatest PPS system features improvements like a quarter-turn locking collar with each lid, domed lid design for better spray performance, wider lid fluid spout and redesigned adapter for a more stable lid-to-gun connection. Each lid strains paint material with a built-in 200-micron filter, commonly used for solvent-based paint materials. Each paint cup (not included) has convenient printed-on universal mix ratios for accurate mixing and a clear access window for easy visibility. Unlike conventional aluminum or other metal paint cup systems, with PPS you don’t have to mix paint in extra cups and filter it into a paint reservoir, so you waste less paint. And with a fresh lid and liner for each mix, there’s less risk of outside contamination. By using this system, you can increase productivity in prep and cleanup time by as much as 50% and use up to 70% less cleaning solvent vs. conventional paint cup systems. Specially designed PPS stainless steel metal adapters let you use the PPS 2. 0 system with virtually any spray gun. Kit contains 16 sealing plugs, 12 disposable liners and 12 disposable lids with locking collar and 200-micron filter.
