Iron stains? AFWFilters it! A pressurized pocket of air at the top of the tank super-oxidizes contaminants which are then passed through a catalytic carbon media to remove them along with a wide range of tastes, odors, and chemicals. Vortech tank improves backwash flow, improving performance and increasing media life. Over 35 years of experience ensures every AFWFilters system provides the results it was designed for, and high quality components mean less maintenance, so you can enjoy YOUR water. Complete AFWFilters Air Injection Gold Series with Fleck 2510SXT Digital Air Injection Control Air Injection Gold System by AFWFilters Fleck 2510SXT digital air injection control Black Vortech resin tank Catalytic carbon media Bypass valve included Single tank design for reduced maintenance Fleck 2510SXT digital air injection control Black Vortech resin tank Catalytic carbon media Bypass valve included Single tank design for reduced maintenance The catalytic carbon media used in this system offers good iron and hydrogen sulfide capabilities. By adding air injection on top of it, the capabilities of the media alone are increased, providing removal of iron up to 15 ppm, hydrogen sulfide up to 15 ppm, and manganese up to 2 ppm. Additionally, unlike most iron filters that only treat iron, hydrogen sulfide, and manganese, the carbon based media reduces a wide range of tastes, odors, herbicides, pesticides, and chemicals. AFWFilters Gold Series Air Injection Specialized control head creates a pocket of air at the top of the tank to oxidize contaminants for easy removal. Vortech tank improves backwash and increases media life. Digital display is easy to setup and offers system status at a glance. AFWFilters designed system is backed by a friendly knowledgable support staff that can help answer any questions you may have. Installation instructions provide guidelines that allow most homeowners to install the system themselves, and video installation tips are available as well. Upgraded Vortech Tank Replacing traditional distributor baskets that are confined to the center of the tank with an edge-to-edge Vortech plate ensure a more effective backwash that prolongs media life. Air Injection 2510SXT Control Head Specialized digital control head creates a pocket of air INSIDE the tank during the backwash cycle, eliminating the separate air tank and expensive pumps of traditional systems. Oxidation and removal inside a single tank reduces wear and tear on the control head at the same time.
