4 Stage Reverse Osmosis System for Aquariums, Drinking Water, Pharmaceuticals, Plant Propagation and Window Cleaning. Features:
VYAIR pumped 4-stage RO system is a new type of aquarium 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 organisms.
This system is equipped with two 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 an in-line cartridge containing granular activated coconut carbon which is designed to remove chlorine and dissolved organic substances.
The main filtration takes place on RO membrane, which removes 96-99% of all impurities from water. Waste water is poured into the drain.
Zero TDS is achievable if your input water is at least 150-200ppm, however if your input water is higher, a second DI filter stage should be considered
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 avialable, consistently out-performing every other brand, pound for pound.
Optional upgrade: 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 system has a factory-fitted electric pump supporting the input water pressure. Raising the water pressure in the system maximizes the efficiency of the osmotic membrane 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 pump supplied with this system is very effective and has been designed for many years of efficient service. Moreover the pump is very quiet. You have to listen closely to know if it is working.
Our aquarium filter is offered as a complete set with filter cartridges, RO membrane, additional accessories and valves preventing the membrane from becoming dried out.
*pH of water after RO system depends on source water.
Operating Pressure: Max. 6.0 bar (90 psi) Min. 2.8 bar (40 psi)
Complete package contains:
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) CTO. 10" coconunt shell carbon cartridge (pre-filter). Activated carbon block filter is used to reduce chlorine, colour, taste, odour and other organic impurities.
3) MR-1812-100. Thin film composite reverse osmosis membrane (100 GPD), 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 recommend purchasing a water storage tank with your RO system.
4) MB-115. 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 that can possibly be made.
IMPORTANT: Do not use with water that is microbiologically 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 two (2) years 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 (call 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.
