i have got one and it is brilliant,even in this cold weather it produces 6lt per minute also it can be taken to site on large jobs and run 3 poles unlike your static systems, get a demo on one from window cleaning warehouse
jason - my ro unit was professionally built for me - it is all housed in framework and has wheels etc so actually mine is every bit as portable ( if I choose), it has everything needed, ro's, prefilters, di vessels etc.
again, less than half price and outperforms everything else.
