Going to upgrade from the hand pump system.
Takes to long for the volume im doing who has a sight that carries the pump and all the fixings including the .45/.22 um replacements?

Hello friend, also use hand pump, and filter 0.45 is very difficult to filter, 0.22 still not tested.

How long does it take to filter and how much through a .22?

The 22 filter pump doesent keep up enough pressure .
Wast of time!

0.45 with the membrane took 10 hours, to filter 250 ml

You may have another issue, i can filter that much with syringe filters in a fraction of that time.
Is your powder really dirty?

I can do 100ml with a syringe filter using unfiltered usp oil in a couple hours... Also looking into a faster system...

Yes, with the hand pump is very tiring, maybe take an electric.
