You mentioned a second filter...Bravo, this is ridiculous small, olny good to keep the pump portable.
Stop screwing around with the BSP stuff...you need to make the conversion once, go to NPT and if your time is worth little, flare everything. i did it for a while, now I buy Swagelock and Parker from ebay at pennies on the dollar, I must have 10 pounds of it here and it cost me like $400.
Best PMV out there a toss up..the big one from Lawrence Factor is really nice, has a replaceable seat... and I use it on one of my compressors, the other is the old Coltri, a lovely piece.
One of the problems with the Aqua environments is they tend to leak down which is really not a good thing. (I think not has bad as some say but it is not good, with your tiny filter is probably does not matter anyway) At this moment I am putting together a k-14 and have Parker 1/4 turn valves immediately before and after the filters to guarantee they stay pressurized. No leak back of the check valve, no leak down of the PMV.

Filters should hold some pressure for a month or more, not necessarily 200 bar, but at least 100 or so.

This K-14 gets another 33" tower, it has the big L.F. pmv and the 1/4 turn parker shutoffs to isolate the filters.

The second filter has a MCH6 filter cartridge in it;

I am confused with your figures though as mine only has MS and AC in it;

Flow Rate Molecular sieve(g) 100 Activated Carbon(g) 25 Hopcalite(g) 20 0 New filter(gram) 113.0 Used Filter(gram) 118.1

I think that's what you are saying? But mine has only MS and AC

0520 replacement cartridge. For use with our personal filter 6300 also Coltri Portable compressor MCH-6

With relation to BSPP, I have no choice. Its Australia, we struggle for NPT. I got BSPP from UK and NPT from US but US postage is a killer. The NRV and filter are all BSPP. The pressure maintaining valve is NPT. I struggled to find all these components and then had to match them up. Not an easy job here in OZ. Swagelock have some parts but not as much as you might think. I was nearly going to have to ask an engineering company to make up specialist fittings.

I do not know how many of the various parts you need..I have dozens/ hundred or more in my air systems, so I have no idea how much it hurts financially, but I can tell you this stuff is not available at all in Vietnam, where I am. I import it at pretty horrific cost, or buy it on ebay and have it hand carried over... One solution for you 37*taper,(JIC) used in car brake lines, may be a choice for you. A good flaring tool is expensive, $120 or so, but you can get very creative making up parts.

You can get h.p. tubing and a handful of npt to JIC, and have at it.
All of my stuff came in by hand with friends, brought used or NOS on ebay in the USA, let me assure it is harder for me to get then you !
3000 people live on the island, anything I want requires a flight to Saigon, and none of this is available there. I even have to fly tp the customs office to get stuff.
Last thing...if you cannot make out the formatting..sorry, i played with it for a while..
As I said..it is right of the bottom of Burtons "Compressor Filter lifeline Calculator" you have a copy, you will find it there. Sheet 1

Ok I missed the flow rate bit, so the rest didn't make sense. Funny how although all the info was there I missed it.

I just wanted confirmation as to the volumes from another source. I like cross checking given I am using the contents to work out end of life of the filter.

Anyway thanks for the info, appreciate it.

I don't need a lot of bits but its frustrating to try and make up a simple setup and have to have a great string of adapters to get the result rather than direct from one thread to another. My second filter looks like a long sausage rather than a nice and neat system.

NPT to JIC fittings are pretty standard all over the world in hydraulic shops, and cost from about $2 in steel (at least that has been my experience)...anyway..find out whatever the hydraulic guys are using locally to go from what ever their machines have to JIC. Get all of your bits threaded with the same thread as your hydraulic stuff, bsp, npt, what ever.
This even gives you (the questionable option) of using whip hose for all of your high pressure connections.
This is the cheap way, once you spend $50 on a tubing bender and $120 oh a GOOD quality flaring tool. Parker is the easy but expensive way, and you need the bender anyway.
Good luck.

Appreciate your comments and yes I agree, one thread type does make life easy.

I am trying to stay with stainless or brass as I am using high levels of oxygen off and on so stay on the side of safety. Hence the need to buy from Swagelock as they are the only ones who seem to sell proper rated fittings in stainless or brass. I steer away from the Chinese specials as they appear to have no pressure rating at all. One brass fitting I bought had so little thread in it, it would not hold a fitting at all. Just far too risky.

If I were just pumping air I would stick with hydraulics as they do have to be rated for high pressure.

Anyway thanks for your comment, I appreciate it.
