Description
The MicroFilter OPP-UV6W 1.0 GPM UV System (without ballast) is a point-of-use ultraviolet water disinfection unit designed to reduce harmful microorganisms — including bacteria, viruses, and cysts — in drinking water. With a compact chamber and 6 W UV lamp, this unit treats water up to 1 gallon per minute, making it ideal for under-sink installations, integration with reverse osmosis (RO) systems, or as a final disinfection stage in small-flow water treatment setups.
※ Ballast / power supply sold separately — this variation comes without the transformer, allowing you to select the appropriate voltage/power option for your installation (110 V or 220 V).
Key Features
