RObust filter advantages

Reverse osmosis filters Ecosoft RObust 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 dishwasher detergents consumption

Ecosoft RObust PRO provides perfect water in your coffee shop.!

Ecosoft RObust PRO is a unique offer for true professionals and connoisseurs of coffee. The filter is designed to meet the world's "coffee" standards and allows you to get water, perfectly revealing the unique taste of coffee.


Water fully complies with SCA (Specialty Coffee Association) standards

Proper water

1 Reveals the taste

With the Ecosoft RObust PRO filter, you can discover the individual taste of your grain thanks to optimal water salinity:

Calcium will fill the body of the drink

Magnesium helps extract fruit acids

Bicarbonates provide a balance of taste and aroma


2 Creates your coffee-design

We customize the water under your grain, so you can create your own unique coffee.


3 Saves your money 

RObust filter is an economical way to get high-quality purified drinking water.


Filtering stages:


— pre-filtering to remove sediments, active chlorine, organochlorine compounds and natural organic matter

— membrane purifying (RO element Dow Filmtec™) provides 99,8% of dissolved impurities, as well as viruses and bacteria

— unique replacement filter RObust PRO provides full extraction of taste and aroma components of coffee due to optimal amounts of calcium and magnesium in water

— special Chemviron Carbon filter to improve taste and odor of water

Reverse osmosis process:

Reverse osmosis is the most reliable water treatment technology. Due to special semipermeable membrane we get an ability of sufficient drinking water purification of all kinds of harmful impurities, incl. viruses and bacteria.   RO membrane pores are 200 times smaller than viruses, and 4000 times smaller than bacteria.

High pressure pump supplies water at the same time to the membrane element and to the RObust PRO replacement filter. RO provides efficient water purification on the molecular level. A special replacement filter provides rich taste and aroma, enriching water with calcium and magnesium. As a result, calcium and magnesium amount, as well as another water parameters meet the requirements of SCA (Specialty Coffee Association).

RObust PRO filter has a dry shutdown function. In case of interruption of the water supply or pressure reduction under the 0,4 bar level, low pressure switch is activated and turns off the valve and the pump. Even in case of purified water tap opening filter will not start until the efficient pressure of water supply recovery.

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

Replacement filter and membrane change

RObustPRO_7.pngThere are 2 manometers on the front panel of RObust 1000. The first shows membrane inlet pressure after pre-treament filters and the second shows pressure on membrane block after pump. The panel shows recommended pressure values for pressure gauges and recommendations for eliminating possible problems if these values do not correspond to the required ones.

Replacement pre-treatment filters

If the pressure after pre-treatment filters is less than 1 bar, this may indicate that the replacement filter need to be changed. Delay in replacing can damage or destroy the membrane. Pre-treatment replacement filters should be replaced after purifying 2 100 gallons of water, but at least once every 3 months. The resource depends on the flow and quality of the feed water.

RO membrane 

If the filtration rate drops significantly, it is necessary to replace the RO membranes. We recommend replacing the RO membranes after purifying of 6 400 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 the 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, an unpleasant odor appears, it is recommended to replace the carbon post-filter. The post-filter should be changed after purifying of 2 100 gallons of water, but at least once every 3 months.

Pump maintenance

Pump operation requires periodic maintenance (the same as other appliances). The main operation of pump maintenance is replacing pump diaphragm.

We recommend replacing diaphragm every 2000 hours of its operation. 

Frequency of replacement:

  • Operating time 12 hours  per day (840-900 liters per day) replacement once in 5-6 months

  • Operating time 8 hours  per day (560-600 liters per day) replacement once in 8-9 months

  • Operating time 4 hours  per day (280-300 liters per day) replacement once in 16-17 month
