Service & Maintenance

The RObust 1500 direct flow reverse osmosis filter is designed for cold water purification only.

Pressure monitoring
The front panel features two pressure gauges:
Inlet pressure gauge – shows pressure after pre-filters.
Pump pressure gauge – shows pressure after the membrane block


1 This value only applies to the RObust 1500, RObust 3000MAX, and RObust 4000 models.


Pre-filtration cartridges
Replace pre-filters after 10,000 liters of water filtration or at least every 3 months.

If the pressure after the pre-filters drops below 1 bar, the cartridges may be clogged.
Delaying replacement may damage or reduce the lifespan of the membrane.


Reverse osmosis membrane
With a significant drop in system performance, replacement of reverse osmosis membranes is required. Replace after filtering 30,000 liters or at least once per year if filtration speed decreases.

Post-filtration cartridge
Replace if taste deteriorates or odor appears, after 10,000 liters or at least every 3 months.

Downtime maintenance
If unused for over 2 weeks, disinfect before resuming use (procedure in the user manual).

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:

How many appliances will use the purified water?

How high is the daily consumption of the purified water?
How big or small is the space available for a water filtration system in your restaurant?
What quality does the inlet water have in your restaurant?
What recovery rates does the RObust 1500 have?

The RObust 1500 offers an excellent recovery rate of 55–60%, making it an energy- and cost-efficient choice for small businesses and professional kitchens.

With a compact size and smart design that hides electrical components, this RO filter is built for continuous operation and reliable daily use, even in tight spaces.
Will water treatment improve food & beverage taste?

Yes, it will.

The RObust 1500 provides purified water that’s free from unwanted tastes and odours, making it easier to achieve consistent flavour in everything you prepare and serve.
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.

RObust 1500 is a direct flow RO system with a high flow rate that makes it a great fit for small to medium-sized restaurants, cafés, and hotels. Its compact footprint and reliable purification performance also make it popular in offices, schools, laboratories, dental clinics, and private homes.
The system provides excellent water quality to protect kitchen equipment and improve the taste of food and drinks.
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. We recommend installing a tank in all cases where our reverse osmosis filters are connected to additional devices.
