|SWT's Non-Backwash Filters are available by customer design (see Part Number
Matrixes below) or by SWT design. To get you started, here are some basic descriptions
of SWT's most popular non-backwash filters and the part number matrix used to
create your own part numbers and impress us with your know-how.
|Non-Backwash Carbon Filters (CFN) are built utilizing SWT's ProActive™ carbon—
the best grade of non-viscous, coal/coconut based, virgin, steam activated carbon
available. These units are designed to be taste, odor, chlorine, color, and chemical
|Non-Backwash SuperCat™ Carbon Filters (SCFN) are built utilizing SWT's
ProActive SuperCat carbon—the best grade of highly reactive, steam activated,
coconut shell carbon available. These units are designed to be 30% more reactive
than other catalyzing carbon filters. They are specially designed to break down
monochloramines that pass through standard carbon filters.
|Non-Backwash Sediment Filters (FFN) are built utilizing SWT's FilterEase™
filtration media. These units are designed to remove ferric iron, silt, and turbidity, and
are preferred when water flow rates and pressures are limited. Sediment filtration as
low as 10 to 20 micron is common.
|Non-Backwash Iron, Hydrogen Sulfide, Manganese Filters (MFN) are built utilizing
SWT's MetalEase™ filtration media as the primary layer. These chemical-free filters
are designed to remove dissolved metals (such as iron), silt, and turbidity from water.
|Non-Backwash Arsenic Filters (MFN-AS) are built utilizing SWT's MetalEase-AS™
(Advanced Structure) filtration media as the primary layer. These chemical-free
filters are designed to remove arsenic and additional dissolved metals from water.
|Empty Non-Backwash Filters (EFN) are built with all of the same great features as
the above systems, but with none of the media inside.
