PureFlo reverse osmosis water filter system <500 l/hr


The PureFlo RO filter is an all-in-one water treatment system, requiring no associated pumps or tanks to operate. Three models supply up to 100, 250 or 500 litres of RO water per hour at a supply pressure of up to 3bar.

The system has a typical total dissolved solids rejection rate of up to 95% and a very high recovery rate, delivering up to 50% of the supply water as RO water.

The unit comes complete with a 3-stage pre-filtration assembly that removes chlorine and any non-dissolved particles down to one micron.

The unit has a 23 litre water tank providing a large quantity of RO water on demand and four pressure gauges showing inlet water pressure, filtration pressure, pump pressure and outgoing water pressure.

These allow for easy commissioning and trouble-shooting.

An optional blend feature allows the quality of the product water to be adjusted.

 Benefits

  • Virtually eliminates scale build-up

  • Reduces maintenance time & cost

  • Reduces energy consumption

  • Provides precise humidity control

  • Extends humidifier life


  •  How it works?

    A PureFlo RO filter uses water pressure to reverse a natural physical process called osmosis. Water, under pressure, is forced through a semi-permeable membrane to filter out minerals and impurities.

    The water entering the system firstly passes through a five then one micron sediment filter to remove any non-dissolved particles. It also passes through a carbon filter to remove chlorine. The filtered water is then boosted to 90-130psi and forced through parallel semi-permeable hyper-filtration membranes.

    These membranes remove on average 95% of the total dissolved solids. These removed dissolved solids are washed away by a constant flow of water to drain.

    The product water is then either delivered direct to the application or is stored in the pressurised storage vessel.

  • Carbon filtration included


  • LED status indication


  • No additional tanks or pumps required


  • 23 litre integral water tank
  •  Why use RO water in humidifiers?

    By removing the minerals from a humidifier’s supply water the limescale that builds up in the system is significantly reduced. This results in a much lower level of required maintenance in all types of humidifier and reduced energy consumption in steam humidifiers. These cost savings can lead to a payback on the initial purchase of the RO (reverse osmosis) unit in under one year.

    Steam humidifiers that run on mains water need to drain their boiling chambers occasionally to maintain a low mineral content and reduce internal limescale build-up. By using pure RO supply water, the steam humidifier’s boiling chamber does not require this regular drain. Therefore it uses less energy to maintain the temperature in the boiling chamber.

    As the temperature within the boiling chamber is consistent, the steam output is also consistent and the humidity control improved. By using resistive steam humidifiers fed by RO water ±1%rH control can be achieved.

    Other benefits of using RO water with humidifiers include increasing the life of the matrices in evaporative humidifiers and preventing dust carry-over in spray humidifiers.
