10 inch Filter Bracket Three Stage


The Filter Bracket Three Stage is designed to take three 10 inch filter housings for RO systems and securely month them to a vertical surface.  The bracket is made from heavy duty steel in a “Z” shape and has universal pre-drilled holes for mounting.

75 GPD RO Membrane


The Vontron 75 gpd RO Membrane is designed with a thin layer composite to provide high quality water filtration from a wide range of water sources.

  • Innovative thin layer composite membrane design
  • Provides high rejection stability even with high TDS
  • Less fouling, less frequency cleaning and more consistent
  • 100% dry membrane maximizing shelf life
  • Lower consumption of chemical and longer life
  • Standard dimensions to fit in commonly available housings

Colour Changing DI Resin Refill


Colour Changing DI Resin will physically change colour to yellow as it becomes exhausted, allowing you to monitor the consumption of the DI resin and know when to change it out.  We recommend testing the TDS before and after the DI Resin to ensure its effectiveness and display early signs of the TDS creeping up through the DI resin.

  • Glycerine Filled Pressure Gauge
  • 1/4 inch quick connect Tee
  • In-line installation
  • 1 – 100 PSI

Inline Ball Valve Push Connect 1/4 inch


The Quick Connect Ball Valve allows you to turn off water flow and isolate parts of your RO system or the entire system.  These ball valves connect in-line and most commonly used to switch off the supply water so maintenance can be performed and filters need to be changed.
