Where It Works
The FPMB series fits standard 10" x 2.5" filter housings and works across potable water systems, beverage equipment, RO pre-filtration stages, fine chemical processing, electronics manufacturing, and plating applications. The food-grade polypropylene construction resists a wide range of chemicals and won't introduce leachables into filtered water. Available model numbers include FPMB1-978, FPMB5-978, FPMB20-978, and FPMB50-978 for different micron grades.
