Durable construction and an economical solution to fluoropolymer, stainless steel or Teflon housings. Pure polypropylene components with no fillers, colorants, plasticizers or lubricants. Ultra-smooth contact surfaces prevent bacterial adhesion and buildup. Resists DI water and other inorganic solutions. Resists stress cracking. All components are pure polypropylene (except o-rings) to prevent contamination from the housing after going through the filter. This All Natural filter housing will help maintain a high standard of purity and performance required in critical contamination control systems and processes. This Pure Polypropylene housing can be used for a variety of applications where purity, quality, filtration and economy are required. Commercial and Industrial Applications for All Natural Housings include: Deionized and reagent grade water. Electronic grade chemicals. Reagent grade chemicals. Reaction solvents for cosmetic, pharmaceutical, or polyester production. Freons (TF, 113). Electronic etching solutions. Magnetic coatings (tape, disc, or card). Reverse osmosis or ultrafiltration final filters.
