The Viqua VT4-DWS (120v) Copper Series UV System by AMPAC USA is a comprehensive water treatment solution designed to deliver safe, clean drinking water directly to your tap. This system combines ultraviolet disinfection with essential pre-filtration, ensuring your water is free from harmful microorganisms and undesirable tastes or odors. Engineered for point-of-use applications, it provides an effective barrier against waterborne pathogens for households and small businesses.

The VT4-DWS utilizes advanced ultraviolet light technology to neutralize bacteria, viruses, and other microorganisms without chemicals. Operating at 120v, it provides a flow rate of 3.5 gallons per minute (GPM) at a 30 mJ/cm² dose, sufficient for most household needs. For applications requiring a higher level of disinfection, the system can deliver a 40 mJ/cm² dose at a flow rate of 2.5 GPM.

Dual UV dose options: 30 mJ/cm² at 3.5 GPM or 40 mJ/cm² at 2.5 GPM
Two 20" filter housings: 5-micron sediment cartridge plus a taste/odor cartridge
Sediment filter protects the UV lamp from fouling and extends system life
Mounted on a heavy-duty, painted steel bracket
3/8" quick-connect inlet/outlet fittings for simple installation

The system is equipped with two 20-inch filter housings, accommodating a 5-micron sediment cartridge and a taste/odor cartridge. The sediment filter removes particulate matter, protecting the UV lamp from fouling, while the taste/odor cartridge reduces chlorine, chloramines, and other contaminants that can impart unpleasant tastes and smells. The entire system is mounted on a heavy-duty, painted steel bracket for durable, straightforward installation.

The 3/8-inch quick-connect inlet and outlet connections simplify integration into existing plumbing. Typical applications for the VT4-DWS include under kitchen sinks, utility rooms, or wherever a dedicated source of purified drinking water is desired, including homes with private well water sources or municipal supplies where extra protection against residual contaminants is wanted.

Frequently Asked Questions

What flow rates and UV doses does the VT4-DWS offer?

It delivers a 30 mJ/cm² dose at 3.5 GPM, or a higher 40 mJ/cm² dose at 2.5 GPM for applications that need more disinfection.

What do the two filter housings do?

One housing holds a 5-micron sediment cartridge that protects the UV lamp from fouling, and the other holds a taste/odor cartridge that reduces chlorine and chloramines.

Where is the VT4-DWS typically installed?

It's commonly installed under kitchen sinks, in utility rooms, or anywhere a dedicated source of purified drinking water is needed, including homes on well water.

How does the system mount and connect to plumbing?

It's mounted on a heavy-duty, painted steel bracket and uses 3/8-inch quick-connect inlet and outlet fittings for easy integration.

Why does the VT4-DWS include filtration in addition to UV?

The pre-filtration removes sediment and improves the aesthetic qualities of the water before it reaches the UV chamber, protecting the lamp and improving taste and clarity.
