Hey everyone,

I am trying to find a way to have a light mobile RODI system and was wondering if, provided I have a 100 psi pump attached to it, the following could produce enough flow rate to allow me to clean windows up to 18 meters heigh:

  • 1 x carbon filter only, which will act as a sediment filter (10microns is more than enough according to my research but maybe I'm wrong)
  • 1 x 4021 HF5 Axeon RO membrane which, with a pump, should be able to produce 2,7 L / minute, which is enough for me.
  • 1 x 2 L DI tank
I can see that most manufacturers create either RODI systems with 1 x 4040 membrane or 2 x 4021 membrane to make sure, I supposed, that flow rate is good enough. But as I'll add a pump in any case, do you think that could be enough?

Any feedback will be really appreciated!
Thanks
Pierre
