Asprinn RO Membrane 75GPD - Suits GT1-70B

Replacement 75GPD Asprinn RO Membrane for KL50784 - 3 Stage Reverse Osmosis Water Filter System for Brewing (GT1-70B).

This 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. 

Replacements of the Stage 1 and Stage 2 filters that protect the RO membrane can be purchased at KB53713 - Replacement Reverse Osmosis Filter Pack - Suits GT1-70B

This membrane is classed by the manufacturer (FILMTEC USA) to be a U.S 75 gallon per day membrane (285 Ltrs). However, these figures are for optimum working pressure/conditions and will rarely apply in the domestic Aussie kitchen.  We predict the production of water to be more like 250-285 Ltrs/day.
