Replace after filtering 60,000 liters or at least once per year if filtration speed decreases.Downtime maintenanceIf unused for over 2 weeks, disinfect before resuming use (procedure in the user manual).Compatible replacement solutionsEcosoft 500 GPD membrane elementEcosoft granular activated carbon replacement filter (4.5″ × 10″)Ecosoft coconut shell carbon block filter (4.5″ × 10″)RObust connection kit for Ecosoft RObust filters
FAQ
What TDS is required for the inlet water?
The required TDS level of the inlet water depends on the filter model.
All our RObust reverse osmosis filters require a TDS level of 1,000 ppm or less except for RObust Coffee. For this one the required TDS is 150-500 ppm.
What water treatment system is best for my kitchen equipment?
While all of our water treatment systems purify water for use in your kitchen equipment reliably, the perfect choice depends on a number of factors like the following:
What recovery rates does the RObust 3000 MAX have?
The RObust 3000 MAX achieves a solid recovery rate of around 55%, ensuring efficient water usage and reliable performance.
Will water treatment improve food & beverage taste?
Yes.
Do you have any RO filters specifically designed for restaurants?
Yes, several of our reverse osmosis systems are well-suited for restaurants, cafés, and other HoReCa businesses. They are designed to deliver high water quality for kitchen equipment, cooking, dishwashing, and beverages — all while offering stable performance and easy operation.
Do I need to use a tank with your water purification systems in my restaurant?
While it’s not strictly necessary to use a tank when using our commercial water filtration system in your restaurant, we do recommend it for certain use cases: For example, using a tank for the water used by your coffee machine helps to average TDS levels in the water, which results in consistent coffee flavour.
