The VT4-DWS combines pre-treatment filters with UV purification to provide a system that combats microorganisms, odors, color and particles commonly found in water. As a point-of-use unit, the VT4-DWS is capable of filtering water for low-flow applications (faucets, water fountains, etc.) at 3.5 GPM. Other features include a stainless steel UV chamber, capable of 100-240V, 50-60Hz, and easy installation. Though the VIQUA VT4-DWS comes in various voltages, be aware of which versions meet your requirements since the electrical connections are integrated into the controller making specific models suitable for specific voltages.
