Osmoseur Osmodyn Slim Pure - Extra-flat, direct flow 1:1, low rejection
Compact reverse osmosis filtration for pure swirl water
The Slim Pure Osmodyn is an extra-flat, tankless solution designed to produce high-quality reverse osmosis water directly on demand. It combines performance, low rejects and simple installation, making it ideal for under-sink use. Extra-flat and water-efficient, it adapts perfectly to your space.
Why an extra-flat osmosis unit?
- Ultra-compact under-sink design
- No storage tank: always fresh water
- Small footprint, discreet installation
- No electronic settings required
Slim Pure offers a sophisticated yet affordable solution for uncomplicated, quality purified water.
Frequently asked questions
Is a tankless RO system less efficient?
No. Slim Pure uses several high-efficiency membranes in series to guarantee performance, vortex dynamization and an output of 30 to 45 seconds/liter without storage.
Is wastewater wasted?
No. Slim Pure minimizes rejection to 1:1, which can be reused for watering or other non-food purposes.
Osmosis Premium vs. Slim Pure
Both Osmodyn models are based on the same high standards: high-performance reverse osmosis, TFC encapsulated membranes, controlled plant-based post-mineralization and vortex dynamization.
The difference is not in the purity of the water (optimal in both cases), but in the architecture and positioning of the system.
Performance & efficiency: optimized 1:1 conversion
Every liter of purified water corresponds to one liter of rejected water. This ratio is significantly more environmentally friendly than traditional high-rejection systems.
Multi-stage filtration
- High-performance activated carbon: adsorption of organic molecules, action against chlorine, pesticides, micro-pollutants, PFAS, heavy metals, chemical oxidants, disinfection by-products, THMs (trihalomethanes). Rinsing head supplied.
- Magnetic anti-limescale treatment: physical action on limescale crystallization, transforming it into aragonite that adheres less strongly to the membranes.
- 3 high-efficiency 180 GPD RO-membranes (Ref HC 180): 540 GPD capacity. Removes 98% of micro-pollutants (nitrates, PFAS, heavy metals, chemicals, bacteria, viruses, nano-plastics, etc.).
- Advanced direct filtration, without reserve, minimized discharge: osmosed and dynamized water instantly at the tap.
- Bio-available mineralization: coconut cartridge (Ref B0200) provides assimilable organic minerals.
- Double vortex dynamization: physical vitalization process in borosilicate glass (neutral).
- EMC protection: purified water without electromagnetic waves.
- Exclusive shielded tube: protects purified water from conducted or radiated electromagnetic fields.
- No electronic components: avoids direct electromagnetic pollution.
- System grounding: drains stray electrical charges and stabilizes electromagnetic potential.
- Stop leak: cuts off the water supply if a leak is detected under the sink.
Configuration options
- Reinforced anti-scale protection: can only be used for connection to an under-sink faucet.
- Faucet: "3-way" (replaces 2-way mixer) or "1-way" (added next to faucet).
Controlled water savings
- 1:1 conversion rate (production volume = discharge volume)
- Purified water flow rate: 1.5 L/min
- Power supply: 36 V
- Warranty: 3 years
Depending on your installation, waste water can be recovered for various uses (watering, sanitary, cistern...).
No programmed obsolescence.

4 steps to commissioning
- Position your osmosis unit on the side of the cupboard or flat.
- Connect the Slim-Pure reverse osmosis unit to the cold water inlet (2 standard fittings supplied) and fit the leak detector/stop valve between the inlet and the reverse osmosis unit.
- Connect the permeate to the filtered water tap (1-way or 3-way).
- Connect the concentrate to the drain (fitting supplied), connect the osmosis unit to an electrical socket, open the tap and use mains water with complete peace of mind.

General warning
- Filters, reverse osmosis membranes and organic remineralization cartridges are consumables with a limited service life (depending on incoming water quality: turbidity, chlorine, excess components, etc.).
- Do not connect to hot water (T<40°C)
- Ambient temperature between 4°C and 45°C
- Cold water inlet pressure required: 2.5 bar (0.25 MPa) to 5 bar (0.5 MPa) with pressure limiter (ideal pressure: 3 to 3.5 bar)
- Pressure units: 1 bar = 100,000 Pa = 100 kPa = 0.000145 psi; 1 Pa = 0.00001 bar; 1 psi = 0.069 bar = 6897.8 Pa
- Depending on hardness, use an additional RING-type anti-scale device.
- If the water is of unknown origin, a physico-chemical and bacteriological analysis will enable treatment to be adapted (salinity > 2000 ppm, iron, manganese, turbidity > 3 NTUs, etc.).
- No control of conditions of use: the user must determine whether the product is suitable for his application.
