SLF-Series – Combined Filtration and UV Water Disinfection for the Home

The SLF-Series is a combined filtration and UV water disinfection treatment system able to remove impurities and safeguard your tank water supplies against bacteria, viruses and pathogens. With 3 models in the range, the SLF-series provides safe, potable water for small, medium and large houses. It can also be used in any other water treatment application where the combination of pre-filtration and UV water disinfection is required.

Complete Water Treatment is achieved in 3 steps

  1. Coarse Filtration – Removes impurities and sediment larger than 20 microns.
  2. Antibacterial Carbon Block Filtration – Improves taste, odour and clarity whilst also removing contaminants greater than 5 microns in size.
  3. UV Disinfection – Inactivates pathogens, bacteria, and viruses.

Standard Features

  • Heavy duty 10” or 20” poly filter housings – depending on the model required.
  • Premium Pleated Filter (20 micron) – provides a high surface area for maximum impurity removal whilst prolonging the filter’s life.
  • Silver Impregnated Antibacterial Carbon Block Filter (5 micron) – improves taste, odour and clarity and prevents bacteria colonisation.
  • High quality 316 grade stainless steel UV reactor – ensures longevity of the system.
  • BSP threaded connections – for ease of connection to plumbing infrastructure.
  • Heavy duty mounting bracket – system permanently mounted securely.
  • Lamp fail alarm – alerts user and prevents untreated water from being consumed.
  • Innovative high output, low pressure UV lamps – target UV dose is maintained throughout lamp life.
  • Pure fused quartz sleeves – allows optimum UV output from the lamp to the water.
  • Lamp parallel to water flow – water disinfected from chamber entry point to exit.

Benefits

  • Convenience – combining filtration and UV disinfection in one unit.
  • No micro-organism is known to be immune to UV – even the chlorine resistant Giardia and Cryptosporidium.
  • Economical and efficient operation – disinfecting at the point of use, no contact time required.
  • No harmful by-products – chemical free, no impact on taste or colour and no corrosion problems.
  • No risk of overdosing – reducing the risks associated with chemical overdosing.
  • Easy installation – units are pre-assembled, only connection to inlet and outlet required.
  • Peace of mind – power supplies show when UV lamp is in operation and audibly alerts any faults.

Options

  • Industrial IP rated outdoor power boxes and indoor power supplies – customised to suit your requirements.
  • Basic indoor controller – lamp on/off LEDs and lamp fail alarm.
