Title: R.O. 4040
Post by: gewindows on January 16, 2013, 07:03:55 pm

HF4 or HF5?

How does one compare to the other regarding performance?

HF4 produces slightly less water than HF5 but at a slightly higher level of purity.

Can't remember which, but one also works better with low pressure.

Ring June at GAPS. Her knowledge is second to none.

I spoke to her, but wanted hands on opinions.

Its the HF5 that works better on the low pressure.
I have just fitted a new 4040 membrane and booster pump from VYAIR this morning (flushing it as I type this)
Its one of these

I previously had an HF5 but running it on low pressure unpumped had shortened its life (2 years).
The VYAIR membrane is supposed to be similar in performance to the HF4.
I will be able to let you know soon how it compares to my HF5.
