OSMOPUR 600 GPD Direct Flow Reverse Osmosis System – Tankless RO with Universal Filters

OSMOPUR 600 GPD Direct Flow Reverse Osmosis System – Tankless, High Flow & Universal Filters

OSMOPUR 600 GPD is a modern direct flow reverse osmosis system designed for customers who want fresh purified water instantly, without a storage tank and without being locked into expensive proprietary cartridges.

Compact, efficient and easy to maintain, OSMOPUR 600 combines fast water production, universal replacement filters and smart protection technology in a slim unit only 14.5 cm wide.

The easy-maintenance direct flow RO system

The main advantage of OSMOPUR 600 is not only its speed or compact design. Its biggest difference is the use of universal replacement filters, helping reduce long-term maintenance costs compared with systems that rely on exclusive cartridges.

This makes OSMOPUR 600 an intelligent choice for anyone looking for a modern tankless RO system with reliable performance and affordable future maintenance.

Fresh water instantly, with no storage tank

Unlike traditional reverse osmosis systems, OSMOPUR 600 does not require a tank to store purified water. Its direct flow technology produces purified water as soon as you open the tap.

This means fresher water, no tank storage and much more free space under the sink.

Professional 4-stage filtration

OSMOPUR 600 uses a 4-stage filtration process designed to produce clean, great-tasting water while protecting the RO membrane and maintaining stable performance.

1. Premium high-surface CTO filter
   Features an outer pleated layer that increases filtration surface area to retain sediment, sand, rust and suspended particles. Inside, high-iodine extruded carbon reduces chlorine, odours, unpleasant tastes and organic compounds.
2. Advanced membrane protection
   The Premium CTO works as the first protective barrier, reducing particles and chlorine before they reach the membrane. This helps maintain flow and extend system life.
3. ROTEK® 3013 600 GPD membrane
   The heart of the system. The reverse osmosis membrane reduces up to 97% of dissolved salts, heavy metals, nitrates, bacteria, microplastics and other contaminants, producing up to 1.6 L/min.
4. GAC post-carbon filter
   As the final polishing stage, water passes through an activated carbon post-filter to improve taste, reduce residual odours and deliver fresher drinking water.

ROTEK® 600 GPD membrane: high production purified water

The reverse osmosis membrane is responsible for producing high-quality purified water. OSMOPUR 600 includes a ROTEK® 3013 600 GPD membrane, designed for fast production without the need for a storage tank.

Excellent efficiency with a 2:1 ratio

Thanks to its high-performance booster pump and direct flow design, OSMOPUR 600 achieves excellent water efficiency: 2 litres of purified water for every 1 litre rejected.

This helps reduce water waste compared with traditional systems, while keeping fast and stable production for daily use.

Simple, affordable and intelligent maintenance

OSMOPUR 600 has been designed to offer easy maintenance and low running costs throughout the life of the system.

While many compact RO systems use expensive proprietary cartridges, OSMOPUR 600 uses high-quality universal components, helping keep the system performing well without depending only on the original manufacturer.

One of the lowest maintenance costs in its category

Buying a reverse osmosis system is not only about the initial price. It is also important to know how much it will cost to maintain over the coming years.

Thanks to universal cartridges and high-quality standard components, OSMOPUR 600 significantly reduces long-term maintenance costs compared with many compact systems that use exclusive cartridges.

Filter replacement designed for everyday users

Periodic maintenance is simple, even for users with no previous experience. Just remove the top cover to access the main filter housings.

Using the supplied wrench, the filter housings can be opened easily to replace the CTO filter or the membrane. The post-filter uses quick connections for fast replacement.
