Hi All
A few people have asked me for information on the various bits for the 3M pps system on the Fuji HVLP; I have sent various pm's over a period and thought it might be helpful to summarise here the key information for reference by others.
The 3M information is spread over various sites apparently directed at specialist auto/aero finishers so it was hard work to find some of this. It is rather confusing, but I got there eventually through browsing some US websites and suppliers.
As far as I can tell, you have two ways to use the pps system with the Fuji sprayguns. Mine is a XT gun which, as I have explained before in this thread
fuji-hvlp-gun-t44034.html, I have converted to a pressurised model; but it looks like the current XPC gun takes the same pps fittings.
You can either:
a) use the mini cup with the no 24 adapter which fits on the side of the gun. Technically, you might be able to fit one of the larger cups, but it would be restrictive and unwieldy in this side position.
The mini cup is available in a normal pressure version where the paint is sucked out by the pressure of the airflow through the gun or in a H/O (for high output) version where the space between the rigid outer cup and the inner liner (which holds the paint) is pressurised by an airline fed from the main airstream. This H/O version is what I got and the only one I can speak for; or
b) use one of the larger cups with the no 18 adapter which fits underneath the gun (appears to be all H/O version) [also it has a rather long stem so failed for me on the compactness requirement].
I went for the mini cup set up as I wanted to use the gun in tight spaces any which way up - I thought the H/O version would be more reliable and I think I read that it was recommended for water based finishes which is all I use. Anyway, I have had good use from the setup - it all works really well, the only drawback being the small cup size which means frequent refilling; obviously against that is the benefit of manoevrability. Here is a picture of the gun with the mini-cup fitted:

Here are the various bits that I bought (I recorded these for my own reference on a useful Word document but could not find a way of attaching the document (it won't allow a Word or pdf document...).
3M™ PPS™ Adapter 24, 16110
Adapter converts the paint spray gun for use with 3M™ Paint Preparation System requiring 1/4 inch Female, 18 Thread NPS. Side mount gravity feed gun cup. Elbow swivel nut.
3M™ PPS™ Type H/O Mini Pressure Cup, 16121
This product is intended for use in place of metal cups on most pressure cup guns. Setting up the pressure cup vs. standard PPS™ is connecting the pressure hose from the cup port to the pressure port on the spray gun, or spray gun regulator.
3M™ PPS™ Type H/O Pressure Hose, 16123
This product is intended for use in place of metal cups on most pressure cup guns. Setting up the Type H/O pressure cup vs. standard PPS™ is connecting the pressure hose from the cup port to the pressure port on the spray gun, or spray gun regulator.
3M™ PPS™ Kit, 16114, Mini size, 200u filters
Kit contains 50 lids with 200 micron filters, 50 liners, and 20 sealing plugs. Graduated measurement to 5 1/2 oz (with generic mix ratio film insert). Max. capacity of 6 fl oz. For use with part number 16115. Note: mix ratio film inserts are sold separately.
I bought the no 24 adapter, the H/O outer cup and some additional pressure hoses (not necessary as the cup came with one, but I wanted some spares) from TCP Global through the US Amazon site - they charged me royally for postage on each item, but then gave me a fair rebate when I complained that it should only have been one charge.
I bought the mini lids and liners from autopaint-pro.co.uk as they were by some way the cheapest price I found online at the time - looking at their website now, they do not seem to stock them. You could perhaps try Morrells if you have an account with them with a decent discount. Seem to be quite alot of items listed on ebay, although some from the US with hefty postage.
[For higher volume stuff, the standard Fuji syphon cup is a problem as I use water-based paint and the aluminium cup is not compatible with water based polymers - it leaves grey smears in the paint and I understand attacks the paint chemical composition; therefore after much further painful research and expense, I have invested in a 2.5L pressure pot system - I have only just commissioned this and will write it up shortly - it is rather good, so now I have the pps system for smaller jobs and the big pressure pot for larger ones].
I hope that is all of some use to someone.
