Felite™ FMB401 is the mixture of Felite™ FC108-H (hydrogen form strong acid cation resin) and Felite™ FA127-OH (hydroxide form type I strong base anion resin) with the ratio 2:3, and is a higher level of Felite™ FMB401-L.

Felite™ FMB401 is designed to produce very high water quality and is intended to use in all mixed bed deionization applications that require high resistivity and high capacity.

Felite™ FMB401 is particularly well suited for portable exchange and other polishing applications. It’s supplied ready to use form, and the resistivity can reach up to 18megohms.
