RObust filter advantages

Ecosoft RObust reverse osmosis filters provide a sufficient amount of pure and safe water for HoReCa needs: for food and drinks preparation, as well as delicious drinking water for guests and staff.

We have combined high-quality water treatment technology, modern design and compact dimensions.

Ecosoft RObust is the perfect solution for HoReCa


— because the purified water does not contain chlorine, pesticides, heavy metals, organic compounds, viruses and bacteria

— due to high capacity there is enough water for everyone


— long service life due to lack of scale

— Up to 50% of usual consumption of dishwasher detergents

RObust 1000 is a compact high-performance reverse osmosis filter. Allows you to get pure, safe water for drinking and cooking.


— — Pre-filtration removes mechanical impurities, active chlorine, organochlorine compounds, as well as natural organic substances
— — Membrane removes up to 99.8% of dissolved impurities, as well as viruses and bacteria
— To improve the taste and smell of the purified water, it is post-processed on activated carbon, Chemviron Carbon



Enjoy tasty and safe water with a RObust 1000 filter!!



Reverse osmosis is the most reliable water treatment technology. Due to the special semi-permeable membrane, sufficient drinking water can be purified of all kinds of harmful impurities, including viruses and bacteria. RO membrane pores are 200 times smaller than viruses, and 4000 times smaller than bacteria.

High pressure pump supplies water on 2 consistently installed membrane elements. Permeate (membrane purified water) after treatment flows to activated carbon filter, and concentrate (waste water) flows to second stage of membrane filtration, that allows sufficient minimization of waste water (concentrate).

After RO-purification concentrate is through the flow limiter is discharged into the sewer. Before the third membrane the second manometer is installed, which monitors pressure in the membrane unit.

RObust 1000 filter has a dry shutdown function. In case of interruption of the water supply or pressure reduction under the 0.4 bar level the low pressure switch is activated and turns off the valve and turns off the pump. Even in the event of the purified water tap opening, the filter will not start until the water supply pressure is restored to an efficient level.


Replacement filter and membrane change

RObust (3).pngThere are 2 manometers on the front panel of the RObust 1000. The first shows the membrane inlet pressure after pre-treament filters and the second shows the pressure on the membrane block after the pump. The panel shows recommended pressure values for the pressure gauges and recommendations for eliminating possible problems if these values do not correspond to the required ones.

Replacement filter maintenance

If the pressure after pre-treatment filters is less than 1 bar, this may indicate that the replacement filter needs to be changed. Delay in replacing it can damage or destroy the membrane. Pre-treatment filters should be replaced after purifying 2100 gallons of water, but at least once every 3 months. The resource depends on the flow and quality of the feed water.

Membrane element

If the filtration rate drops significantly, it is necessary to replace the RO membranes. We recommend replacing the RO membranes after purifying 6400 gallons of water, but at least once a year, in order to obtain purified water of constant quality.

In the case of long interruptions in filter operation (over 2 weeks), it is necessary to disinfect the filter (the procedure is described in detail in the manual).

Carbon post filter

If the taste of purified water is significantly degraded, and an unpleasant odour appears, it is recommended to replace the carbon post-filter. The post-filter should be changed after purifying 2100 gallons of water, but at least once every 3 months.
