UV Guard SLT-12 Under Sink UV Water Disinfection System
The UV Guard SLT-12 is a compact under sink UV water disinfection system designed to help make drinking water safer by destroying harmful microorganisms using high-performance ultraviolet light.
Part of UV Guard’s trusted SLT-Series, the SLT-12 is ideal for point-of-use drinking water applications where reliable, chemical-free UV disinfection is required after suitable filtration.
Why Choose the UV Guard SLT-12?
- Destroys 99.99% of pathogens to help make water safe for drinking
- Australian WaterMark certified for safe, fit-for-purpose performance
- Durable 316L grade stainless steel UV reactor
- Compact under sink design for point-of-use drinking water protection
- Easy to install and maintain
- 1/4" Tube Push Fit inlet and outlet connections
- Uses UV-C disinfection technology, with no chemical dosing required
How It Works
The SLT-Series uses ultra-violet light in the germicidal wavelength range between 200 and 300 nanometres. The optimum wavelength for UV disinfection is around 264 nanometres, which sits within the UV-C spectrum.
As water passes through the stainless steel UV reactor, microorganisms are exposed to UV-C light. This high-energy light is absorbed by the DNA of bacteria, viruses, spores and other pathogens, damaging them so they are destroyed or unable to reproduce.
