RObust 4000 direct flow reverse osmosis filter is an innovative product designed specifically for dishwashers in restaurants or similar environments where space is limited. This ultra-compact direct flow reverse osmosis filter boasts the highest flow rate in the RObust filter range, all without the need for an additional tank. RObust 4000 features a stainless steel body, seamlessly designed to match the general style of other restaurant equipment.
RObust 4000 direct flow reverse osmosis filter provides advanced water purification, making it suitable for a wide range of applications. Here’s how the system operates:
- Pre-filtration:
Tap water first undergoes initial treatment through sediment and carbon filters to remove mechanical impurities, chlorine, and organic substances. - Membrane filtration (Ecosoft RO Elements):
Water is then pushed through two semi-permeable reverse osmosis membranes. These membranes remove up to 99.8% of dissolved impurities, including viruses and bacteria. The membrane pores are 200 times smaller than viruses and 4000 times smaller than bacteria, ensuring superior purification.
The membranes divide the water into two streams:
- Permeate: Pure, filtered water suitable for use.
- Concentrate: Water with a high concentration of impurities, which is flushed to the drain.
Water-saving function:
The built-in water-saving feature increases the production of purified water compared to earlier models, reducing waste.
Enhanced performance:
With two high-performance Ecosoft membranes, the system ensures high-quality water purification and significantly improved productivity.
This combination of technologies guarantees efficient, reliable filtration for a variety of applications.
