Introducing our newest model to our ever increasing range of reverse osmosis systems. This system has been designed with the latest technology of the PI filters. Assembled here in Australia with quality components from countries like America, United Kingdom and New Zealand.
By using only quality products on our system we can offer the most reliable systems on the market.
Benefits of using our PI filters are that it Adds beneficial minerals, including, Calcium, Potassium, Magnesium and trace minerals. Unlike many PI available in Australia, our PI filters are factory assembled so you know what materials you are getting in your PI filter.
Promotes high level of PH in the body- helps neutralize acidic body conditions- some acidic conditions are associated with diabetes, arteriosclerosis, high blood pressure and other chronic conditions. Expect to get an PH of 9-10.
The PSI 021-5P-PI has a TW30-1812-75GPD membrane. This membrane will produce approximately 300 litres at 50 PSI applied pressure over a 24 hour period. If your mains supply water has a sufficient pressure the system will produce more water over the 24 hour period. The system is supplied with a membrane flushing valve. When used (Recommended to be operated every 3 months) it will flush any salt or calcium build up on the membrane prolonging the life of the membrane.
Minimum water in feed pressure for the reverse osmosis system to operate is 40 PSI (272Kpa). Without this mains pressure you will need to have an electric pressure pump for the system. If you are unsure of your water pressure you will need to check with your local water body on what pressure you have.
This reverse osmosis system removes 95-98% of Fluoride.
This system is supplied with QMP 300-HP water filter housings. These housings have a burst strength of 575psi (4000kpa). We have found these housings to be the most reliable housing available. Even with such a highly rated housing we still supply a Pressure limiting valve with the unit. This pressure limiting valve limits the pressure that is applied to the system. As the system is under pressure 24/7 it is an essential part of any water filter system under the sink. Many systems in Australia aren’t supplied with PLV’s due to the expensive purchase price of them.
Dimensions of the main filter unit are

49cm high,  35cm Wide and 14cm deep.

Dimensions of the storage tanks are:
4.2L- 33.5cm high x 20.5cm diameter

9L- 39cm high x 24cm diameter

12L – 39cm x 29cm diameter

When choosing a storage tank take into consideration that you can also lay the tank down . Most installations the storage tank is put into a back corner of a cupboard out of the way. The main filter unit is supplied with approxatly 2m of tubing on the storage tank line so you can place it away from the main filter unit. These sizes for the storage tanks can be optioned in the checkout. 4.2L and 9L are a no cost. The 12L is a $5.00 Upgrade. If these size tanks are not large enough for your needs we have other larger sizes available but you will need to give us a call to obtain pricing and availability of these tanks. All of the tanks that PSI Water Filters supplied are Stainless Steel and Meet NSF certification.

Stages of the PI Filter:

Stage 1
Volcanic Red Clay Ceramic Balls
Infra red emission and negative ionisation
Removes harmful ions and energises the water
Reduces water molecule or cluster size
Stage 2
Mountain Anti Oxidisation Minerals
Calcined Lime Silicate, Mica and Quartz Compound
Significantly reduces negative ORP
Strong anti oxidising effect
Stage 3
Granular Magnetic Tourmaline Rock
Softening and conditioning mineral content
Energises water
Further reduces water molecule or cluster size
Stabilises negative ORP generation
Stage 4
Granular Phlogopite Rock
Adds mineral (potassium/magnesium) ions
And alkalises the water
Infra red emission and negative ionisation
Reduces water molecule or cluster size
Stage 5
White Quartz Ceramic Balls
Strong anti bacterial function
Mineralises (calcium/magnesium ions)
Alkalises and energises water
Stage 6
Condensed Bio Life Deep Sea Mineral Mix
With Ionised Deep Sea Coral and Porphyries
Mineralises (sodium/potassium)
Significantly increases and stabilises pH level of water
Stages of this system, Costs of operating the system and lifespan of the filters.

Annual running costs on this system are approximately $160.00.
Cartridge change times are dependent on water quality and usages. It is only a guide.
To connect the system to the mains in feed supplied you will need to check what type of connection you require. There are many different types of connection the PSI can supply with the water filter unit. Three of the mains connections are Braided line connection 1/2”, Dishwasher connection3/4” and Tee Olive connection ½”. The mains connection needs to be connected to cold water only. If you require a connection other than the three that the showed here, contact us and we can tailor make a connection that is suitable for your application.
