If you want great-tasting, high-quality water without buying bottled water, then this is the system for you!

Apart from food, people today depend on water for healthy living. When water becomes contaminated, individuals may be exposed to life-threatening illnesses.

Our four stage water filter system is a professional under-counter system that helps to reduce harmful contaminants that find their way into groundwater, directly affecting private wells and municipal water systems. It is ideal for under sink point-of-use installation and provides a continuous supply of clean, filtered water that is suitable for households of all sizes.

This system is equipped with three pre-filtration stages. The first is a sediment cartridge made from spun polyester. It effectively removes sediments including sand, silt, dirt, rust, etc. The second is a granular coconut shell carbon GAC cartridge, which is designed to remove chlorine, pesticides and volatile organic compounds. The third is an extruded activated carbon block, which will further remove chlorine, colour, taste and odour. The main filtration takes place over two high quality “three-layer-configuration" composite membranes, each of which consist of a thin polymer layer deposited on top of a porous polymer layer on top of a non-woven fabric support sheet, and are placed after the filters, facilitating the removal of 96-99% of all contaminants from the water, including mechanical impurities, bacteria and most viruses (0,0001μm and larger), ensuring outstanding water quality and providing faster flow on demand. Waste water is poured into the drain.

Two heavy-duty factory-fitted electric pumps support the input water pressure. Raising the water pressure in the system maximizes the efficiency of the osmotic membranes and thus ensures good performance from the RO system. If your water pressure is less than 2.8 bar then a system with a pump is highly recommended. The pumps supplied with this system are very effective and have been designed for many years of efficient service. Moreover the pumps are very quiet. You have to listen closely to know if they are working.

Further key features of this system include a high pressure switch to be used in conjunction with an automatic shut-off valve if adding a water storage tank, enabling the system to eliminate waste by closing the feed line when the tank is full or shut down and conserve power when the water pressure reaches 30 PSI. Automatic and manual flush valves to purge the reverse osmosis membranes prior to use, and a low pressure switch to safeguard the pump should the water supply fail, are also included as standard.

Our four stage water filtration 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 membranes, additional accessories and valves to prevent the membrane from becoming dried out.

ADVISORY: Avoid cheap water filtration systems and cartridges which have no testing credentials or certifications, and often leach harmful chemicals into the water which are linked to cancer, birth defects and infertility. In addition, cheap components may also lead to membrane fouling, leaks and general poor performance. Instead, always choose VYAIR tested and certified water filtration systems and cartridges.

STAGE, PART#, COMPONENT, FUNCTION:

  • 1) PP. 10" sediment cartridge (pre-filter) melt-blown polypropylene. 5 micron sediment filter traps dirt, sediment, rust and other particulate matter.
  • 2) GAC. 10” granular activated carbon cartridge (pre-filter). Coconut shell granular is used to reduce chlorine, colour, taste, odour, pesticides and organic impurities
  • 3) CTO. 10" coconut shell carbon cartridge (pre-filter). Activated carbon block assures high-quality pure water by further reducing chlorine, colour, taste, odour.
  • 4) RO-1812-200. Dual thin film composite reverse osmosis membrane (200 GPD - US Gallons - each), 0.0001 micron. Semi-permeable membrane removes salts, minerals, metals, bacteria, viruses, cysts, TDS, hardness, fluoride, pesticides, lead, mercury, cadmium, arsenic and more. Due to the time needed to remove all these ingredients we strongly recommend purchasing a water storage tank with your RO system.

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. Regularly scheduled maintenance and replacement of the filter cartridges is recommended in order for the product to perform as specified.
As with all RO diaphragm pumps they are not designed for 24/7 operation and you need to rest the pump for 30 minutes every 4 hours. This can be achieved using a low cost plug-in timer.
Replace the filter cartridges at least every 3 or 6 months (depending on water quality).
Replace the RO membrane every 2 to 3 years (depending on water quality).

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.
