Oasis DP RO Reverse Osmosis System – Under Bench Drinking Water

Oasis DPRO Reverse Osmosis System – Under Bench Drinking Water

High level water treatment for homes wanting maximum filtration performance.

The Oasis DPRO is an under-bench reverse osmosis system designed to produce very high quality drinking water by removing a wide range of contaminants. It uses a multi-stage filtration process, including a reverse osmosis membrane, to treat water down to an extremely fine level.

The system includes a small storage tank, allowing treated water to be available on demand through a dedicated tap.

What’s Included

807274 – Oasis DPRO reverse osmosis unit
807293 – 5 micron sediment cartridge
807311 – granular carbon cartridge
813177 – 5 micron carbon block cartridge
807277 – reverse osmosis membrane
807278 – post carbon polishing cartridge
807279 – mineralising cartridge
Storage tank (approx. 8 to 11 litres usable capacity)
Dedicated drinking water tap

How It Works (Simple Explanation)

This system uses multiple stages of filtration, each with a specific role.

Stage 1 – 5 Micron Sediment Filter

Removes dirt, rust, and larger particles from the water. This protects the downstream filters and improves overall system performance.

Stage 2 – Granular Carbon Filter

Reduces chlorine, which is important for protecting the RO membrane and improving water quality.

Stage 3 – Carbon Block Filter

Further improves taste and odour while removing finer sediment and organic contaminants.

Stage 4 – Reverse Osmosis Membrane

This is the core of the system. The membrane filters water down to approximately 0.0001 micron, removing a wide range of dissolved contaminants.

Stage 5 – Post Carbon Filter

Polishes the water after the membrane, improving taste before it reaches the tap.

Stage 6 – Mineralising Cartridge

Adds beneficial minerals back into the water to improve taste and balance after the RO process.

Performance

Production rate up to 189 litres per day
Approx. 0.13 litres per minute
Approx. 7.7 minutes per litre
Storage capacity 8 to 11 litres

What This System Improves

Reduces chlorine and chlorine byproducts
Reduces dissolved contaminants
Improves taste and odour
Removes sediment and fine particles
Reduces organic contaminants
Provides high level filtration through RO membrane
Improves taste through mineralisation

Important Considerations

This system uses a dedicated tap and does not supply your main kitchen tap.

Reverse osmosis systems produce water slowly, which is why a storage tank is included to provide usable flow at the tap.

RO systems also produce wastewater as part of the filtration process, which is normal for this type of system.

This system requires a minimum water pressure of 300 kPa and a maximum of 800 kPa to operate correctly. If your pressure is lower than this, a booster pump version is available. See the Boost Oasis DPRO for low pressure applications.

Running Costs (Realistic Expectations)

Filter and component replacement occurs at different intervals depending on usage and water quality.

Estimated cost of ownership
$27.19 per month
$326.33 per year

Note on running costs

These figures are provided as a guide based on typical usage and maintenance. Actual replacement costs will vary depending on water quality, usage, and how well the system is maintained.

Drinking water applications
Homes wanting high level filtration
Reducing a wide range of contaminants
Customers wanting premium water quality
Situations where standard filtration is not sufficient

Do You Actually Need Reverse Osmosis?

Reverse osmosis is one of the highest levels of filtration available, but it is not always necessary.

For many homes on good quality mains water, a standard carbon filtration system will already improve taste, odour, and general water quality to a level most people are happy with.

Reverse osmosis becomes more relevant where there are concerns around dissolved contaminants, or where a higher level of treatment is preferred. It is also often chosen by people who simply want to take water quality as far as possible.

It is worth understanding that RO systems are more complex. They produce water more slowly, require multiple filter changes, and come with higher running costs compared to standard filtration.

In most cases, the right system comes down to your water source, your expectations, and how far you want to go with treatment.

Why People Choose This System

This system provides a much higher level of treatment compared to standard filtration.

It is suited to customers who want maximum control over their drinking water quality, with a proven multi-stage process that removes a broad range of contaminants and delivers consistent results.
