C-Series Black Manganese Stains Filter

The C-Series system that solves it

This is a full C-Series system built on three parts that work together: a C-Series air-injection control valve on top of an air-injection oxidizing tank, filled with the media matched to your water. The valve draws a fresh air charge and backwashes on schedule, flushing the oxidized contaminants to drain automatically. One consistent C-Series platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.

What it does for your home

• Removes black manganese stains from your water
• Clear water with no orange, brown or black staining
• No rotten-egg or metallic smell
• Protects fixtures, laundry and appliances
• Self-cleaning — the system backwashes itself
