*****NEW!! 2019/20 MODEL*****

This clever and stylish RO unit is suitable for larger practices with between 5-8 chairs (surgeries) and up to 4 autoclaves in softer water areas – where the mains (potable) water quality is under 250ppm CaCO3 (if unsure, you can check your water hardness on your local water utility company’s website).


* unique ‘bayonet’ connections on ALL 5 catridge stages: which means any of your staff can change them in seconds without any tools, thus avoiding stressful and costly downtime associated with changing cartridges in other RO systems.

* built-in TDS meter after the 5th stage, to give you an accurate live water quality reading, which ensures water quality is always ‘fit for purpose’ in autoclaves and dental chairs.

* proprietary biofilm cleaning kit means users can address both ‘organic’ (eg bacteria) and ‘inorganic’ (eg limescale) issues quickly and easily, often without needing to call out an engineer.

In addition, the Eau Flow 505 includes:

  • a 5 stage RO water filter with easy maintenance ‘quick release’ cartridges, including ALL connection components  (non-return valve, washing machine valve, 1/4″ to 3/4″ BSP)
  • choice of dispensing valve or counter-top tap
  • 8m of plastic tubing (1/4″/ 6.2mm)
  • Larger 20L storage tank.

NB – Water hardness and its impact on RO performance for your autoclave and dental chairs: The most important issues that affects the quality of water coming out of your RO system and hence when you need to change cartridges,  is the water quality in your area (normally determined by limescale and nitrates), plus your RO water consumption. If you fit this unit in a hard water area, you will need to change cartridges every few months.  If your water hardness is higher than 250ppm, we recommend you add the high capacity Di cartridge (EY30810) plus the inline TDS meter (EY20155), which should ensure you do not need to change any cartridges on your RO for 1 year, under normal conditions.  If unsure, you can email us for help.
