The “New Backwashing” KDF/GAC whole house water filter provides chlorine-free and chemical-free water to the whole house for up to 700,000 gallons or 7 years!
Two medias are used, KDF-55 media for de-chlorination and heavy metal removal and Granulated Activated Carbon (GAC) to remove taste, odors and chemicals. The KDF media is contained in a special 4-segment chamber that is attached to the riser tube. The water enters here first where the KDF media is swirled, increasing the contact time with the water. The KDF media de-chlorinates the water, removes heavy metals and makes the entire filter system bacteria static (Prevents Bacterial Growth).
Upon exiting the KDF chamber, it enters the activated carbon to remove foul taste, odors and chemicals. The “New Autotrol Performa 263/740 Logix Control Valve” automatically backwashes the KDF and GAC every 6 days in most conditions, using only 15 gallons of water to remove dirt, sediment and keep the media in peak condition through out its life. The valve is 1” valve but can also connect to 3/4” plumbing (connects 1” or 3/4” copper or CPVC tail pieces). An integrated by-pass switch is included to allow by-passing the unit for uses not requiring filtered water.
