Our 4-stage compact RO system is a new type of aquatic RO filter. Water after it has been passed through an RO system has a reduced pH*. It is an excellent source to prepare appropriate conditions for aquatic application.

This system is equipped with two pre-filtration stages. The first is a sediment cartridge made from spun polyester. It effectively reduces and removes sediments including sand, silt, dirt, rust, etc. The second is an in-line cartridge containing granular activated coconut carbon which is designed to reduce and remove chlorine and dissolved organic substances.

The main filtration takes place on RO membrane, which reduces and removes 96-99% of all impurities from water. Waste water is poured into the drain.

The final 'polishing' stage is provided via mixed-bed ion-exchange resin. It consists of a carefully blended mixture of virgin raw materials, strong acid cation and strong base anion resins. It is widely recommended for all non-regenerable mixed-bed applications where reliable production of the highest quality water is required, and where the resin must have an absolute minimum of ionic and non-ionic contamination before it is used. Any pre-contamination in the resin will reduce its overall lifespan, so a high quality resin will last longer.

Our MB-115 mixed-bed formulation is regarded by all in the water purification industry as the best performing mixed-bed de-ionisation resin available, consistently out-performing every other brand, pound for pound. Colour-change resin turns from green to yellow when it has expired, meaning you have a visual indicator of when your resin will need replacing. Ordinary resin usually requires to be checked with a TDS meter, however colour-change resin means you can tell at a glance when it is time to renew the resin.

This reverse osmosis water filter, like all direct flow reverse osmosis water filters, does rely on you having a strong mains water pressure. Please do not buy this item if you do not have a good water pressure. This unit operates best at input water pressures of between 30psi (2 Bar) and 60psi (4 Bar). We would suggest that this is not suitable for use with gravity-fed cold water systems (where the water is stored in the loft). Normal UK water pressure should start from around 2 bar or above.

Our system is factory tested and ready to use with connection hardware, tubing and instruction manual, all of which is designed to make installation and maintenance quick and easy without the need for a plumber.

It is offered as a complete set with filter cartridges, RO membrane, DI resin, additional accessories and valves to prevent the membrane from becoming dried out.

*pH of water after RO system depends on source water.

  • Ideal also for household use, perfect for small families, kitchen compact and will easily fit into any under counter space
  • This system will improve the aesthetics of water used for drinking and cooking

Complete Package Contains:

  • The 4-Stage Compact is supplied with the following cartridges: PP, T33
  • 1 litre MB-115 mixed-bed colour-change DI resin (provides approximately 2 fills of the resin chamber)
  • Feed water connector (can be fitted to copper mains water pipe)
  • RO membrane element type: RO-1812-50 thin film composite
  • Outside tap connector and spanner for RO housing
  • 10" transparent housing for DI resin chamber
  • 1/4" tubing for system connection (5 metres)
  • 300cc flow restrictor and manual flush switch
  • Instructions manual

STAGE, PART#, COMPONENT, FUNCTION:

  1. Inline PP - 10" in-line sediment cartridge (pre-filter) spun polypropylene. 5 micron sediment filter traps dirt, sediment, rust and other particulate matter.
  2. T33 Inline Carbon - 10" in-line coconut shell carbon cartridge (pre-filter). Activated carbon filter is used to reduce chlorine, colour, taste, odour and other organic impurities.
  3. 50GPD Membrane - Thin film composite reverse osmosis membrane (50 GPD - US Gallons), 0.0001 micron. Semi-permeable membrane reduces salts, minerals, metals, bacteria, viruses, cysts, TDS, hardness, fluoride, pesticides, lead, mercury, cadmium, arsenic and more. Due to the time needed to reduce all these ingredients we strongly recommend purchasing a water storage tank with your RO system.
  4. MB-115 Resin - Mixture of cation and anion de-ionisation resin combined in a 40/60 blend. Mixed-bed demineralizer is used for final water polishing to clean the last few ions within water prior to use. A single pass through a mixed-bed ion-exchange column results in the purest water that can possibly be made.

Important: Do not use with water that is micro-biologically unsafe or of unknown quality without adequate disinfection before or after the system. Water filtration systems can help reduce the presence of contaminants. In addition, some water filtration systems can help reduce the presence of micro-organisms or other contaminants that pose potential health risks.

 

Limited Warranty: Vyair warrants that this product is free from defects in materials and workmanship. This warranty, together with any and all warranties implied by law, shall be limited to a period of twelve (12) months from the date of original purchase. This limited warranty does not apply to failures that result from abuse, misuse, alteration or failure to properly comply with installation, or cartridge change instructions. Vyair strongly recommends adding to all point of use filtration systems a Pressure Limiting Valve (contact us for further details) to guard against unwanted extreme water pressure events, pressure increases, surges, and water hammer which could occur in the water pipes. Not having one installed could mean that if you ever did have to claim damage caused by a burst water filter system, your claim could be denied.

What should my water pressure be?

Between 3-4 bar. If between 1-3 bar, consider a pumped system.

What Gallon-Per-Day (GPD) is this system?

This is a 50GPD system.

How often should I replace the filters?

Change the pre-filters every 6 months or their recommended lifespans (whichever comes first).

  • Average lifespan of inline particle/sediment filter is 8,000L
  • Average lifespan of a inline carbon filter is 9,500L

How often should I replace the membrane?

The membrane should be replaced every 12 months (as long as regular maintenance of the pre-filters and flushing is completed, see above for average life-span).

How quickly does this system make water?

This system produces water at a rate of 7.88 litres per hour (LPH). This is providing that you are running the unit in optimum conditions with the correct water pressure and water temperature.

What is the waste water to pure water ratio of this unit?

This unit has a waste to pure ratio of 3:1, meaning 3 litres of waste water to every 1 litre of pure water (running at optimum conditions).

Troubleshooting steps if the unit isn't working - Initial Checks

  • Check the power to the system
  • Check the water supply to the system
  • Check the power plug is switched on
  • Check the fuse in the plug and check the fusebox

What information will be needed when requesting technical advice?

  • Age of the system
  • When the filters were last changed
  • When the membrane(s) were last changed
  • Incoming water pressure
  • Incoming water TDS
  • Pure water TDS
  • Pure water production
  • What position the flush valve is in
