VIQUA VH410/2 UV Light System, 18 GPM, 220V
The VIQUA VH410/2 is an ultraviolet disinfection system that delivers up to 18 GPM of treated flow on a 220V/60Hz supply. It uses high-output UV lamp technology in a compact stainless steel chamber to inactivate bacteria, viruses, and protozoa without adding chemicals. A constant-current ballast maintains stable UV output regardless of line voltage fluctuations.
Designed for whole-home, point-of-entry residential water treatment, cottages, and OEM integration. With 3/4" FNPT connections, it fits a wide range of household and small-commercial installations where microbial protection is required. Replaces the legacy Sterilight S12Q-PA and SC-320 systems.
