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



— 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


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 purified water 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 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 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 sufficiently minimization of waste water (concentrate).

After RO-purification concentrate is through the flow limiter is discharged into the sewer. Before third membrane is installed the second manometer, which monitor pressure in 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 low pressure switch is activated and turns off the valve and turns off the pump. Even in case of purified water tap opening filter will not start until the efficient pressure of water supply recovery.

Filter RObust 1500 is intended for purification cold tap water only.

Replacement filter and membrane change

RObust (3).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 filter maintenance

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.

Membrane element

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 to replace 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
