Portable Aquarium Reverse Osmosis Water Filters Fish 200GPD RO DI Filter + Pump ROPS4-DJ

Portable Aquarium Reverse Osmosis Water Filter 200GPD RO DI + Pump – ROPS4-DJ Portable

Portable Reverse Osmosis Water Filter 200GPD – 4-Stage Deionising RO Purifier with Booster Pump

This portable RO DI system is locally assembled, pressure-tested, and performance-rated locally at our Queensland premises. Designed for marine aquariums, hydroponics, and other applications requiring ultra-pure water, it delivers exceptional water quality without a storage tank or permanent plumbing. Its portable design allows it to be easily moved or stored, making it ideal for temporary or flexible setups.

Final Stage DI Polishing:
The final 10"x2.5" mixed resin DI filter reduces the TDS (total dissolved solids) of your water to 0–1ppm, ensuring virtually contaminant-free water. This system is perfect for aquariums or other non-consumption uses. It is not suitable for drinking water due to the ultra-pure output.

Production Capacity:
With a 200GPD TFC membrane, this portable system produces up to 760 litres per day, depending on feed water quality and pressure (variances up to ±10%).

Filtration Effectiveness:
Reverse osmosis technology removes 99.99%-100% of common water contaminants, including fluoride, chlorine, cysts, bacteria, and heavy metals.

Contaminant Reduction Table:

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.

SYSTEM SPECIFICATIONS:

*Where the feed water TDS reading is high, the minimum operating pressure of the unit may be affected. If your feed water TDS is in excess of 400ppm we recommend that you consult us before you purchase. Generally these systems are suited to most town mains water supplies, however if you are intending to use the unit on tank or bore water we recommend testing the feed pressure and water quality first.

* Standard mixer taps refer to a mixer tap where you can unscrew the aerator on the end of the tap and will be left with either a 20mm female thread or a 23mm male thread. If you have the 20mm female thread you'll need to use the inside to outside thread converter [in the 3rd picture and supplied with this item] to connect but if you have a 23mm male thread after removing the aerator you won't need to use the thread converter
