Comes with instructions by AFW Filters also on USB drive. Iron is a common problem in homes today. It causes red staining on fixtures, turns clothes and sometimes even your hair a reddish orange color. Sulfur is easily detected by the presence of a "rotten egg" odor, and is sometimes associated with yellow staining. Manganese is most often seen as a black slimy substance that builds in standing water, and may impart a metallic taste to the water. All of these problems can be eliminated with our Air Injection System. Using the principle of oxidation, the system forces the contaminates into contact with oxygen. Most older air injection systems consist of either two separate tanks or by using a Venturi valve to inject air into the water. cleaned and/or replaced. By utilizing a patented piston, our Air Injection system is able to put the whole oxidation process inside one tank, keeping maintenance costs and down time to a minimum. This is done by creating a bubble of pressurized air at the top of the tank (done during the backwash cycle). The air in the tank then oxidized the contaminates, with the Filox media trapping them. Then every few days the system automatically backwashes itself, rinsing the contaminates off the media and replenishing the air bubble. This system is chemical free, and is able to remove higher contaminate levels than most other tank systems on the market. Using the new K series media combined with air injection you remove the most iron, sulfur and manganese problems without worrying about dangerous chemicals. Complete system includes tank, riser tube, deflector, control head, media, and bypass valve. Online installation instructions provide detailed steps on filling, installing, setting up, and maintaining your system. New K series air injection, only requires half the backwash flow rate of the regular air injection systems! Saves water!
