Automatic backwashing screen water filters.

Product Information

The ABW-Series is a range of reverse rinsing or automatic back wash screen filters that ensure a continuous supply of filtered water.

  • Filtered water supplied even during reverse rinsing
  • Patented reverse rinsing system – fast and thorough cleaning of the filter with small amount of water

It also protects downstream pipes, appliances and fixtures from damage caused by sediment and rust.

UV Guard Applications

Our market-leading UV disinfection systems deliver outstanding results across an extensive range of industrial, commercial and domestic applications.


The HWC-Series took a few weeks to clean the calcium build-up from the pipes and the results were astonishing. I honestly cannot speak more highly of the product and installation was so easy.

Since installing the water conditioner we are using less washing powder, soap and shampoo. The life of our hot water element also appears to have been extended.

Sally, WA

Since installing our Shower Water Conditioner, the whole family has noticed the difference. We all have softer, more manageable hair and my son no longer has as many skin irritations.

Allison, NSW

Before installing UV-Guard’s Hard Water Conditioner, Calcium used to build-up on every surface, Iron was also staining our toilets and basins. Now there is no Calcium build-up and the Iron staining is easily wiped away.
