Product Features
The new Universal Water
backwashing KDF/GAC whole house filter provides chlorine-free
and chemical-free water to the whole house for up to 700,000
gallons or 7 years! The "reverse flow" backwashing (done
automatically) keeps the media free of fine sediment and silt,
prolonging its life and enabling it to function at peak
performance. The media can filter chlorine and chemicals
effectively with flow rates up to 10 gallons per minute (the
system can accommodate flow up to 20 gpm), with minimal pressure
loss (less than 2 psi loss at 60 psi). All components are NSF
certified.
Two medias are used -
KDF-55 for de-chlorination and heavy metal removal and
coconut shell Granulated Activated Carbon (or 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 (including lead),
and makes the entire filter system bacteriostatic (prevents
bacterial growth). Upon exiting the KDF chamber, it enters the
activated coconut shell carbon to remove bad tastes and odors,
chlorine by-products, and chemicals.
 The
new Autotrol Performa 263/740 Logix control valve, with
solid-state electronics, automatically backwashes the KDF and
GAC (once a week in most conditions) to remove dirt and sediment
and keep it in peak condition throughout its life. Sediment is
also removed down to about 20 microns, and then is backwashed
down the drain. For ultra clear water, add our
SPF-1 high-flow sediment filter as a post filter to go down
to 1 micron! The valve is a true 1" valve but can also connect
to 3/4" plumbing (choose 1" or 3/4" copper or PVC tail pieces to
connect to). An integrated by-pass switch is included to allow
by-passing the unit for uses not requiring filtered water (such
as lawn watering). The unit stands about 60" tall and is 10" in
diameter. Requires drain near by (floor, wash basin, overhead,
etc.) and standard 110V outlet (uses less electricity than a
night light). Since it requires cutting the main water line, a
professional plumber may be needed.
Note on chloramines: To
reduce the potential for the formation of THMs, some US municipal
supplies are converting their chlorine (Cl2) disinfection method to
chloramine addition. Chloramines are chemical complexes formed from the
reaction between ammonia and chlorine. They are more attractive to some
municipal water suppliers because unlike chlorine, chloramines do not
combine with organics in water to form THMs. While our standard KDF/GAC
whole house water filter can effectively remove chlorine and much of the
chloramine, chloramines require a greater contact time with regular
carbon and so may not be entirely removed. Calgon Carbon manufactures a
catalytic carbon called Centaur Catalytic Carbon, specifically made for chloramine removal, and it is highly effective. In addition to
chloramine removal, it is also highly effective at VOC, taste and odor
removal, and even hydrogen sulfide and iron removal in well water
applications. If your water supplier is using chloramines as a
disinfectant, you should consider our WH-EXL-CC option - it uses the
catalytic carbon in place of the standard coconut shell carbon. If you
are uncertain, simply call your water department.
NOTE: The WH-EXL is designed for
primarily for municipal water that is free of iron and sulphur.
We do offer whole house water filters for private wells to solve
a wide variety of problems - click
