Filtration

Filtration systems are used to remove impurities from water by means of a fine physical barrier, a chemical process or a biological process. 

Filters cleanse water to different extents for purposes like irrigation, drinking water, aquariums, ponds and swimming pools.

Filters use sieving, adsorption, ion exchanges, biological metabolite transfer, and other processes. Unlike a sieve or screen, a filter can remove particles much smaller than the holes through which the water passes.

Most filtration systems will remove sediment, chlorine, heavy metals and other impurities.

Double Under Counter In Line with KDF
Double Under-Counter In-Line 10" with KDF (DUCFIL)

On-demand purified water at your sink or prep-bow with this dual stage in-line filtration system which is installed under the counter/sink in line so you can use your existing tap/mixer.

Unlike Reverse Osmosis, this unit does not remove the existing minerals from the water and does not waste any water.

 

  • Premium Two-Stage 10 Inch Under-Counter Filtration System.
  • Uses your existing faucet/tap/mixer.
  • Flexible 1/2" pipes included (as illustrated in image).
  • KDF Media Filtration.
  • Up to 99% Chlorine reduction.
  • Pure drinking water.
  • Unit can handle up to 6 bars of pressure.


Housings incorporate a dual o-ring design to reduce risk of leakage.

KDF filter cartridges will reduce or remove chlorine, hydrogen sulphide, iron, mercury, lead, magnesium, chromium and up to 98% of water-soluble cat-ions (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals.

KDF Media is also bacteriostatic.

Whilst removal rates depend on a number of factors, more than 98% of chlorine is removed by KDF filtration media.

Unsure of your water pressure? We recommend purchasing the optional pressure reducing valve to further reduce risk of leakage, it is not uncommon for water pressure to surge which is why we recommend using the pressure reducing valve if your water pressure is over 4 Bars.

Note:  This system can NOT be used on the HOT water line. This system can only be installed on the cold line.

Reverse Osmosis System
Reverse Osmosis System 125GPD 450LPD with Pump (RO-125P)

Reverse Osmosis is a process where water is demineralised using a semi permeable membrane at high pressure. Your normal filtration units will only reduce certain contaminants such as silt, rust, chlorine and bacteria (up to 96%). Reverse Osmosis machines will purify your water up to 99.9% or 0.001 microns, thus removing other dissolved contaminants like Colloid, lead, mercury, germs and other metals.

 

Stage 1 : Polypropylene Cartridge – 5 Micron Superfine Filter – Removes solid particles & impurities i.e. silt & rust.

Stage 2 : Granular Activated Carbon (UDF) Filter – Absorbs odours, chemicals & chlorine.

Stage 3 : Carbon Block Filter (CTO) – removes additional chlorine & water decolourants.

Stage 4 : Reverse Osmoses Membrane – Removes up to 0.0001 microns colloid, metals, germs & bacteria.

Stage 5 : Post Carbon Filter (T33) – improves water taste.


Faucet and necessary installation fittings are included.

Operating Pressure: 50 - 100 psi (3.5 to 6.5 bar)

 
If your water pressure is bellow 3.5 bar you will require an RO with a pump.
If your water pressure is above 6 bar you will need a pressure reducing valve to keep your pressure within the operating pressure limits.

 

This unit produces up to 125 Gallons or 450 litres every 24 hours.

This unit includes a pump so an electrical outlet is needed nearby.

We recommend that a plumber install the unit as a pressure reducing valve may be required.

Please note: The unit does not have the white cover or pressure gauge as shown in the picture.
