The AFW Filters Air Injection Platinum system creates a bubble of compressed air at the top of the tank. As water flows through the system the contaminates are forced into contact with oxygen. This causes them to oxidize into a larger form which is then trapped by the Filox/Mangox media. By using a combination of a highly capable filter media and air injection, the Platinum system Controlled by the Fleck 2510SXT control head, this system automatically backwashes. The backwash process uses no chemicals, simply using the force of water to clean the media and flush the contaminates down the drain while replenishing the air bubble. Made by Fleck, the #1 manufacturer of control heads in the US, the digital control head allows for easy user interaction, automatic backwashing, a professional look. The advanced air injection design allows for air injection in a single tank, which is a significant advantage over two tank or venturi (inline) injection systems. By containing the oxidation process to a single tank routine maintenance is reduced, part replacement and associated costs are decreased, and less space is required.
