[Name]: high-quality 10-inch embossed PP cotton filter filter pore size is 5 m and 1 m. Delivery upon request, if no request, the default will be shipped randomly ~ - ~! [Description]: Dimensions: length 25.4CM, outer diameter: 6CM, inner diameter 3CM Weight: about 120 grams [Filter introduction]: PP filter (polypropylene meltblown filter): ★ The PP cotton brand water purifier filter support ( can be used for most domestic, commercial water purifier such as Angel, the United States, Patio, and other domestic brands purifier) ??★ PP high fiber material hardness, deformation after filtration, by no means comparable to some of the soft PP cotton. ★ This product PP fiber material with high hardness, no deformation after filtration, by no means comparable to some of the soft PP cotton. ★★★ Note: Some PP cotton filter to intercept too soft will not achieve the role, but also because of the pressure and deformation, resulting in incomplete filtering effect filters and water purifiers behind life. The melt-blown PP filter: resistance to weak acid and most organic solvents and inorganic solvents. Mainly to remove: suspended solids, sediment, rust, colloid, hair and other impurities. Operating Pressure drop characteristic parameters: 0.1kgf / cm2 maximum pressure: 4kgf / cm2 maximum voltage drop: 2 kgf / cm2 maximum operating temperature: 60 ℃ using odorless, non-toxic polypropylene as raw material, melt, injection, traction, receiving a forming a tubular filter.
