Portable Reverse Osmosis System

The NEW FSA Portable Reverse Osmosis System has been designed specifically for Brewing & Manufacturing. The GT1-70B unit has been specifically configured to run Sediment --> Carbon --> Membrane which provides straight Reverse Osmosis water with no further influence from post filters such as alkaline filters or GAC carbon filters. 

The lack of post filter allows the pH to remain stable at a range of 6.2 - 6.5 pH with a TDS of <10 (Dependant on several factors). Regular RO units that have post GAC filtration (usually for drinking water) elevate the pH of the water to as high as 10.5pH due to the reaction the pure water has on the Activated Carbon in its new state.

The unit is fitted with a standard 3/4" Female Garden Tap Adaptor but you can purchase and additional laundry block adaptor or a kitchen tap diverter valve using the checkboxes in the listing

Kit Contains

  • Inline Sediment Filter 5uM
  • Inline BL@CKFREE Coconut Carbon Filter (Acid Washed)
  • 75 GPD Asprinn Membrane
  • Inlet 3/4" Adaptor
  • Instruction Manual
  • Tubing, Clamps & Fittings (Pre-Assembled as per photo)

Stage 1: Inline 5uM Sediment filter

Poly Spun is the best type of filtration you can get. They do not accumulate bacteria as much as other materials, as well as being high flow and low pressure drop. Effective in all applications. 5 micron is a reasonably fine filtration and would be suited on high quality bore water or town water or infront of RO's.

100% Virgin Polypropylene material - Compatible for Our Watermark Certified Systems

Purefer Polypropylene filters are made using a unique single nozzle manufacturing process, where a single nozzle blows melted polypropylene onto a spinning 5 micron filter core. As more Polypropylene is blown, the filter diameter gradually widens and the outer density of the filter decreases.

Stage 2: Inline BL@CKFREE Carbon Filter

The World’s First Patented Filter that Protects RO Membranes and Faucets

An internal polypropylene post filter is inserted into the filter cartridge to prevent carbon fines from escaping. Eliminates “carbon black” from water while protecting the RO membrane and faucet from carbon fines, extending RO membrane and faucet life. Protects the Safety of Drinking Water with Increased Chlorine Removal Efficiency

Incorporates bacteria resistant PET pads instead of foam sponges, thus ensuring drinking water stays pure and uncontaminated.

All parts are sealed using advanced friction welding, eliminating the need for glues

Cartridges are filled with 100% coconut shell activated carbon with an iodine number of 1000 for improved chlorine removal efficiency.

Inline Filters and UDF Cartridges are filled with 100% pure coconut shell activated carbon with an iodine number of 1,000 for improved chlorine removal efficiency.

Industry’s Highest Pressure Rating

Cartridge body designed to withstand high pressures.
Minimum burst pressure exceeds 500 PSI.
Reduces risk of damage and/or rupture from water hammer.

Stage 3: Asprinn 75GPD RO Membrane (FilmTec Material)

Removes 98% of impurities including organic and inorganic, chemicals. The membrane, is the "engine room" of the reverse osmosis filtration system. All the work is done here, so all the filters before the membrane are primarily there to protect the engine. This membrane will produce up to 75GPD (280L/24hr) of clear pure water @ 70psi within the working feed water quality requirements.
