The VIQUA D4-V UV treatment system is third-party certified by the NSF to treat flow rates of up to 8.9 GPM. Common situations with this flow rate include small house (1-3 Bedroom) treatment and some light commercial applications. Capable of 100-240V, 50-60Hz.

If you're looking for a reliable UV system, the ultraviolet light of the VIQUA D4-V deactivates the DNA of microorganisms in the water so they are unable to reproduce. This reduces microbial contaminants ranging from bacteria to viruses.
