The main image displayed is on the 20"x4.5" unit and 2nd and 3rd images show the smaller 10"x4.5" housings and filters.
Watermark certification is not a requirement with commercial systems unless you plan to use this unit in a domestic household connected to mains water supply then you may require housings with Watermark certification and brass ports which we can supply for $100 extra and the onus is on you to let us know if you require Watermark certification at the time of ordering as changing this after the unit has been dispatched will cost up to $500 more if we have to ship a unit to you, have it shipped back and change the housings to be Watermark certified ones then ship back to you.
NB: The main listing images are of the marine grade stainless steel brackets and if you don't select this option in the drop down selection menu and select the while bracket you will receive a system with a white painted mild steel bracket. We have not included the option of a 10"x4.5" pre-filters with 2x 500GPD membrane for +/- 3,900L/24Hrs as the 10"x4.5"pre-filters will not last long enough at this flow rate.
Our range of passive RO units for commercial applications are designed to operate at town water pressure. These systems don't require power as they have no pumps or electronic controls. This RO unit is assembled and tested in our Queensland factory before shipping to ensure proper operation.
The reverse osmosis process results in the total dissolved solids (TDS) count dropping by between 90% to 95% depending on your local environmental factors, system design and waste ratio. This purification process is commonly considered to be the most effective method of purification available, and will consistently produce water with the lowest level of contaminant. Where water of a higher standard (99-100% contaminant reduction) is required, mixed resin post filters may be fitted on request for an extra charge.
This system will produce up to 3,800 litres per day depending on your selection in the drop down menus given optimum feed water pressure. *Note: Your local water pressure and quality of the feed water can cause this estimate to vary by up to 15% as the recommended waste ratio will be higher if you are filtering water with a TDS reading above 500ppm.
This unit is tested on a town water supply, if you plan to use this unit on any other kind of supply (bore, creek, tank etc.) we strongly recommend performing basic water tests (TDS, Salinity, Hardness/Calcium and Iron) to determine whether the water is within the systems operating parameters. If you are unsure as to whether this unit suits your needs, feel free to send us a message with any details you have on your water.
All of the parts that come into contact with the water in our systems are manufactured from BPA free food grade plastics. All of the filters and parts that we source are of the highest quality and meet the required quality standards.
This system can be optioned with either 10"x4.5" or 20"x4.5" pre-filters. The 20 inch filters are capable of filtering roughly twice as much water between filter changes and the 20"x4.5" pre-filters are recommended for the higher volume units.
SYSTEM INCLUDES:
- 1x white mild steel or 316 grade SS mounting bracket.
- 2x big blue pre-filter housings with 1"BSP ports.
- Available in either 10x4.5" or 20"x4.5" BB sizes.
- 1x 1 micron poly spun sediment disposable filter.
- 1x standard** / higher*** volume carbon block filter.
- 1x 500GPD* or 2x 500GPD* TFC NSF RO membranes.
- Appropriate ring spanner to loosen pre-filter housings.
- Installation kit including a roll of tubing and tap adapters.
* GPD = Gallons per 24 hours x 3.8 litres for litre per 24 hours.
* 500GPD + 1000GPD units use Global Aqua RO membrane.
** standard volume 10"x4.5" will remove chlorine for +/- 45,000
litres and standard volume 20"x4.5" will remove chlorine for
+/- 100,000 litres
*** higher volume carbon filter will remove around 3x more
chlorine than standard volume ones and chlorine needs to be
removed by the pre-filters as it damages the membrane
SYSTEM REQUIREMENTS:
- Minimum feed pressure: 60psi
- Optimum feed pressure: 75-85psi
- Optimum temperature: 10C-40C
This RO unit carries a full 24 month warranty on all parts supplied in the original order, this is subject to our standard terms and conditions listed in our operating manual
NB NOTE: Watermark certification is not a requirement with commercial systems unless you plan to use this unit in a domestic household connected to mains water supply then you may require housings with Watermark certification which we can supply for $ 100 extra and the onus is on you to let us know if you require Watermark certification at the time of ordering as changing this after the unit has been dispatched will cost up to $500 more if we have to ship a unit to you, have it chipped back and change the housings to be Watermark certified ones then ship it back to you.
Why Choose the High Volume RO Passive Commercial Purifier?

This system is designed to operate on town water pressure, meaning it requires no power, pumps, or electronic controls. It is assembled and tested in our Queensland factory to ensure proper operation. This unit effectively reduces total dissolved solids (TDS) by 90% to 95%, consistently producing water with the lowest level of contaminants.
Compact Design and Powerful Performance
This system is built for high-volume use, with options for either a single 500GPD or a dual 1000GPD RO membrane. It can be optioned with either 10"x4.5" or 20"x4.5" pre-filters, with the larger filters recommended for higher-volume units. The system includes a 1-micron poly spun sediment filter and a carbon block filter to protect the membrane, which can filter up to 100,000 litres of water between changes.
Seamless Integration and Easy Maintenance
This unit is designed for straightforward installation with 1" BSP ports and an included installation kit. It comes with a mounting bracket (available in either white mild steel or marine-grade stainless steel) and an appropriate ring spanner for easy filter housing maintenance.
