Twin Cartridge 20″ x 4.5″ Sanic Whole House Rainwater Filtration System

With Inbuilt Antimicrobial Technology



Product Info

Product Description

Twin filter cartridges remove unwanted sediment through a 10-micron polyester pleated cartridge followed by a 5-micron  silver impregnated carbon cartridge to remove colour, taste and odour. Silver is used to inhibit the growth of bacteria on the cartridge. Pressure gauges indicate water inlet and outlet pressure.


Superior System Quality, Warranty & Performance

Each Filtatank rainwater filtration system is hand-built and assembled in Australia by the team at The Tank Doctor. With over 20-years experience selling and installing rainwater filtration systems, you are assured of an extremely high quality product with excellent after sales support.

Components are individually laser cut, folded, welded and assembled by Australians using Australian materials. We use only the very best quality components in each filtration system.

High quality Filtatank systems include stainless steel water pressure gauges that indicate inlet and outlet pressure across the filtration system. This is helpful to indicate when the filtration cartridges require servicing or replacement. Usually the filter cartridges are replaced on an annual basis, depending on the volume of water usage and the quality of the water supply.

Why would you trust the health of your family with anything less!

Microban® antimicrobial product protection is a built-in biocide silver that enables the filter housings to resist the growth of microbes such as bacteria, mould and mildew. By creating an inhospitable environment this disrupts the metabolism of contaminating microbes by preventing conversion of nutrients into energy. This inhibits microbial survival, reproduction and colonization and disrupts vital cell functions of the microbe.

Water filtrations systems incorporating Microban® protection ensure filter housings stay cleaner, last longer and stay fresher in between cleanings than products with untreated surfaces. This sets Microban® antimicrobials apart from many other competitor products in the market today.

Patented Design

Filtatank systems use the very best quality Italian made Sanic Antimicrobial filter housings. Patented one-piece housing tops ensure leak-free connection between housings with extreme rigidity and structural strength across the whole filtration system.

These unique filter housings help to prevent trapped bacteria feeding on dirty filter cartridges which will reduce taste and odour in the rainwater supply.

With a pressure rating of 120psi and 3-year warranty, the filter housings surpass all other systems with ease.

The difference between the Filtatank Twin and Triple cartridge rainwater filtration system is the addition of a 5-micron poly spun filter cartridge (in stage two of the triple system). This cartridge is designed to capture finer particles following the 10-micron pleated first stage cartridge. This will protect the silver carbon cartridge which is only designed to absorb colour, taste and odour and doesn’t prefer a lot of dirt particles.

The twin system is ideal for the standard size family home with decent quality rainwater. If the water is quite dirty and brown in colour and there is a high demand on the filter system then we recommend installing the triple cartridge filter system.

Simply mount the filtration system to a house or shed wall and then connect the plumbing to the 25mm BSP inlet and outlet water ports. There is no noticeable loss of water flow or pressure with this filtration system installed!
