Description
RO C500 tankless reverse osmosis system for professional use and larger homes
RO C500 is a high-flow direct reverse osmosis system designed to produce purified water without a storage tank. With a 400 GPD membrane, integrated booster pump and output up to 65 L/h, it is suitable for larger homes and small professional environments such as cafés, bars, offices, gyms, beauty salons, B&Bs and small workplaces.
The system supplies ambient-temperature reverse osmosis water for drinking, cooking, beverage preparation and daily use where compact installation and higher water production are required.
Who is RO C500 ideal for?
- Cafés and small bars: for drinking water, tea, coffee preparation and beverage service.
- Offices: for staff kitchens, meeting rooms and shared drinking water points.
- Gyms and wellness studios: for clients and staff who need better-tasting drinking water.
- Beauty salons and hair salons: for cleaner water at the point of use.
- B&Bs and small hospitality spaces: for guest kitchens or common areas.
- Larger homes: for families that need more purified water than a small tank RO system can provide.
Main advantages of the RO C500 reverse osmosis system
- Tankless direct flow: no storage tank required.
- High capacity: up to 65 L/h, about 1500 L/day.
- 400 GPD membrane: suitable for higher daily water demand.
- Booster pump included: supports operation even when inlet pressure is not ideal.
- Pressure gauge included: helps monitor system operation.
- Sturdy metal chassis: reinforced bracket with stainless steel screws.
- Standard 10 inch cartridges: easy and economical replacement.
- Installation kit included: tubes and long-reach faucet with metal handle.
- Compact under-sink installation: suitable for homes, offices and small commercial premises.
4-stage filtration system
The RO C500 uses a 4-stage filtration process designed to reduce sediment, chlorine taste and odor, many dissolved impurities and total dissolved solids. Actual performance depends on inlet water quality, pressure, membrane condition and regular maintenance.
- Sediment pre-filter: melt-blown polypropylene cartridge, 5 micron.
- Granular activated carbon cartridge: helps reduce chlorine taste, odor and organic compounds.
- Carbon block cartridge: additional carbon filtration before the membrane.
- Reverse osmosis membrane: TFC 3013 membrane, 400 GPD.
Filter cartridges and membrane used in RO C500
The system uses common and widely available filter formats, making maintenance simple and cost-effective.
- 1st stage: Green Filter / Ionicore melt-blown polypropylene cartridge 9-3/4 inch, 5 micron
- 2nd stage: Green Filter / Ionicore granular activated carbon cartridge GAC 9-3/4 inch
- 3rd stage: Green Filter / Ionicore / Aquaphor carbon block cartridge 2.5 x 9-3/4 inch, 5-10 micron
- Alternative 3rd stage: Pentek SCBC-10 silver carbon block cartridge 2-7/8 x 9-3/4 inch, 0.5 micron
- 4th stage: LG / Greenfilter / Ionicore Keypra TFC 3013 reverse osmosis membrane, 400 GPD

Why choose a tankless reverse osmosis system?
Traditional reverse osmosis systems often use a storage tank because the membrane produces water slowly. The RO C500 uses a high-capacity 400 GPD membrane and a booster pump, allowing direct-flow operation without a tank.
This is useful where more purified water is needed during the day, such as offices, cafés, bars, gyms, beauty salons and larger homes. The tankless design also saves space and avoids storing water in a separate pressure tank.
RO C500 for cafés, bars and offices
For small professional premises, RO C500 offers a practical balance between capacity, compact installation and serviceability. The system can supply reverse osmosis water for drinking, coffee and tea preparation, beverage service and daily staff use.
The use of standard 10 inch cartridges makes maintenance straightforward, while the integrated pump helps maintain stable performance where water pressure is not high enough for a passive reverse osmosis system.
RO C500 for larger homes
In larger households, a small tank reverse osmosis system may not always provide enough purified water during peak use. RO C500 is designed for higher flow and daily production, making it a good choice for families that need more water for drinking, cooking and kitchen use.
Installation and maintenance
Professional installation is recommended, especially for commercial or B2B environments. The system can be surface-mounted or wall-mounted, depending on available space and installation layout.
Regular filter and membrane replacement is important to maintain water quality and system performance. Replacement frequency depends on inlet water quality and daily consumption.
Compliance and product notes
The RO C500 is stated as compliant with UNE149101, Italian Decree 25/2012 and Italian Decree 174/2004. Installation and maintenance must follow the supplied manuals and local water treatment regulations.
Some minor technical details, components or colors may vary depending on production batch or version.

Frequently asked questions
Is RO C500 suitable for a café or small bar?
Yes. Its high-flow 400 GPD membrane and up to 65 L/h output make it suitable for small cafés, bars and beverage preparation points where a compact tankless system is preferred.
Does RO C500 need a storage tank?
No. RO C500 is a direct-flow tankless system designed to produce purified water without a storage tank.
Can RO C500 be used in an office?
Yes. It is suitable for offices, staff kitchens, shared drinking water areas and small workplaces with regular daily water demand.
Does the system include a pump?
Yes. RO C500 includes a booster pump, which helps improve membrane performance and supports operation where inlet pressure is not high enough for a passive RO system.
Can the system be upgraded?
Depending on the installation, the system may be supplemented with accessories such as a UV lamp or TDS controller. Any upgrade should be evaluated by a qualified installer.
What kind of water does reverse osmosis produce?
Reverse osmosis helps reduce dissolved salts, chlorine taste and odor, many heavy metals, nitrates, pesticides and other dissolved contaminants. Actual reduction depends on water quality, pressure, membrane condition and maintenance.
