US Water Systems Flexx Oxi-Gen FX-250 Owner's manual

Brand: US Water Systems

Model: Flexx Oxi-Gen FX-250

Type: Owner's manual

This manual is also suitable for

Flexx Oxi-Gen FX-150

US Water Systems Flexx Oxi-Gen FX-250 uses air injection to change the ferrous iron to ferric iron and oxidize sulfur, eliminating the need for harsh chemicals. Controlled by a simple-to-use app, the system includes a meter to track water usage and a 9-volt battery backup to ensure uninterrupted operation during power outages. With fully adjustable cycle times and NSF-approved components, the FX-250 effectively removes iron (up to 12 ppm), hydrogen sulfide (up to 20 ppm), and manganese (up to .7 ppm) from water sources with pH levels ranging from 6 to 9.
