Applications
RObust 1500 is designed to provide a high flow rate of pure water in a compact size for cafes, hotels, offices, schools, laboratories, dental offices, private homes, etc. The design hides all electrical components from external influences, but maintains convenient access to all replaceable elements, ensuring quick system maintenance.
Description
ECO-ROBUST1500
The ROBUST PRO Reverse Osmosis Filter is a high-performance water filtration system designed to provide you with clean, purified drinking water. It uses a reverse osmosis process to remove contaminants, including heavy metals, chlorine, bacteria, and more, ensuring your water is safe and great-tasting. By investing in the ROBUST PRO, you'll enjoy the benefits of healthier, better-tasting water for you and your family.
The ROBUST 1500 system is a four (4) state reverse osmosis system with pressure pump, capable to produce up to 1,890 liters of clean drinking water per day

Filter service life
5 000 L but not less than once in 3 months. Service life depends on feed water quality and intensity of usage
Membrane service life
40 000 L but not less than once a year
If pressure of water in your system does not meet requirement, install a pressure booster pump to raise it. If water pressure exceeds the upper limit, install a pressure regulator before the RObust.
Using the RObust with feed water temperature between +20 and +30 °С produces a lower rejection rate and higher flow rate, which yields higher TDS of purified water. Using the system with feed water above +30 °С is
advised against.
