Wholesale Ecosoft RObust 3000 reverse osmosis filter

Water for ice makers/Water for drinking and cooking

RObust 3000 is a compact high-capacity reverse osmosis filter. It allows to get clean and safe water for drinking, cooking and water for ice makers.

Water purification consists of the following stages:

  • pre-filtration removes sediment impurities, chlorine, chlorination by-products and natural organic compounds

  • reverse osmosis membrane (Dow Filmtec™ RO membrane) eliminates 99.8% of dissolved impurities, viruses and bacteria

  • post-filtration by Chemviron Carbon activated carbon improves the taste and odor of water

Key advantages

  • Dow Filmtec™ membranes (USA) removes 99.8% of all water impurities, including bacteria and viruses

  • Original and compact design

  • Built-in indicators of control of pre-filters replacement and system operation

  • Designed for tankless operation

Reverse osmosis is the most advanced technology of water purification. Thanks to a special semipermeable membrane it is possible to efficiently purify drinking water from virtually all harmful impurities, including bacteria and viruses. The pores of this membrane are 200 times smaller than the viruses, and 4000 times smaller than the bacteria.

The principle of the filter is to divide the initial water by a semipermeable membrane into two streams: purified water - permeate, and water with a high content of impurities - concentrate, which is discharged into the sewage system.

In the RObust 3000 filter there are two Dow Filmtec™ reverse osmosis membranes. This allows not only to obtain high-quality water but also to significantly increase the productivity of the system, thereby ensuring the supply of purified water to the consumer directly without the use of a storage tank.

The filter contains a thoughtful connection panel, visualized by pictograms, which makes it simpler and more convenient to use. Special indicators allow to monitor the efficiency of the filter and change replacement filters in time. In addition, progressive automation provides electrical protection of the pump against dry running.

The RObust 3000 reverse osmosis filter is designed for treatment only cold water.

On the front panel of RObust 3000 there are two pressure gauges, one of which displays the inlet water pressure after the pre-filters, and the second - the pressure after the pump in the membrane unit. In addition, for user convenience, the special information label shows recommended pressure values ​​for pressure gauge and recommendations for resolving possible problems if these values ​​do not correspond to those required.

If the pressure after the replacement filter is less than 1 bar, this may indicate its contamination. Procrastination with the change of replacement filters can lead to damage or destruction of the membrane. The pre-filters replacement should be changed after treatment of 15000 liters of water, but at least every 3 months. The resource depends on the consumption and quality of the purified water.

If the filtration rate drops significantly, reverse osmosis membranes must be replaced. To obtain purified water of unchanged quality, we recommend replacing reverse osmosis membranes after treatment of 70000 liters of water, but at least once a year. In the event of long breaks in the filter operations (more than 2 weeks), it is necessary to disinfect the filter (the procedure is detail described in details the manual).

If the taste qualities of purified water deteriorate significantly, an unpleasant odor appears, it is recommended to replace the carbon post-filter. The post-filter should be changed after treatment of 15000 liters of water, but at least every 3 months.
