Wonder if this is a fix???

Reason i ask is all of a sudden in last 3 to 4 months had strange problems pop up with different items and everything was done right also using the PPS cups, finally one painter took out the strainer and problem went away, so the next 20-30 calls I had the people do that and bingo all is well.
Then talking to a jobber and I brought it up, he said he had run into problems also and was returning inventory to his warehouse and the salesmen told him they they had a new manufacture making these and they were a problem.
So i don't know whats going on except what I hear on streets But just a heads up.

I recently upgraded to the 2.0 system after using the original pps for years. There are several upgrades in the new setup. A bigger and better strainer is one, that may solve the issue Barry mentioned. The lids fit much better into the disposable tips and the gun adapters. I always felt a little uneasy with the way the cup wiggled. Now it's very snug. The lids are more domed for better flow. The opening is nearly twice the size to allow better material flow. They did away with the collar so each lid comes with a built in locking system that attaches directly to the cup. The cups have a slot in them to allow you to push the used liner out. Also, each lid/liner kit comes with a new cup included. I heard that their patent ran out and that's why they made the changes, but who knows. In my opinion, I think it's worth upgrading.

How do they compare to the Devilbiss De-Kups system? Who has the best disposable cup system?
I never used the 3M PPS, 3M 2.0, or the Devilbiss. What's best depends on what features you like, cost and ease of use. The Sata RPS system looks the best to me because I like a positive vent and appears to be a simple well thought out system. I know the collapsible cup allows for spraying upside down but that just isn't very important to me.
I'm curious about the new 3m because it looks simple (lid-cup) and has a positive vent. But I have no clue how they are going to compare. Will the vent need to be manually switched or work automatically? Will they work in existing adapters (PPS) or will it be all new adapters? How will they compare in cost? And most important will they function reliably? Another reason I'm looking for answers about the new 3M is should they work in the existing adapters I have most of my guns covered. With Sata it would be all new (7-8) adapters excluding Sata quick couple.

Very strange! That link I posted has changed and I can't find any trace of the above mentioned "vented disposable cups"! They are gone, images everything. Real weird.
Plenty of info about their 2.0 units with the liners, not interested.

I like the De-Kups so far working good for me and use them almost every day and will give a quick wash out when used for base and reuse for 2k primer. Just make sure lid is on tight. Don't ask LOL

Had another call yesterday from a very top notch shop, been using spi for years and when we went through the 10,000 question of why all a sudden
they were having problems with the good base he was using and clear, I said you doing everything perfect, than I said what kind of cup and bingo
just recieved more a week ago and it was the one ones, he is taking filter out and will report back today. (3m cups)
Hes using Sikkens base also.

not a fan of this type system. lot of landfill waste . i've been here on the farm for 20 years and still have an inch to go in my drain pan . oil drain pan will hold about 300 to 400 gals of trash thinner.

Like you mentioned earlier they are having problems with these.
What I'm not crazy about is the collapsible liner, no vent. Seems to me the closer that liner gets to the bottom the more it would resist and not completely drain the cup. But more important a variation in the rate of flow from full to empty?
Also not liking that retaining ring that gets reused, a source for trash to build up.
I don't know why we can't have something simple, reliable and cost effective. Closest I came to that goal was the Finixa Paint System (Europe). I had a couple of issues with them initially but they ended up working quite well. The Finixa consisted of a cup, with a lid that had a built in vent with no need to operate anything, and two choices of mesh strainers that I didn't have any problems with. Simple and cheap, use and dispose of, But! they are not available in the USA any longer, figures.

Yes ! I couldn't find that.
After a few screw ups I wrote that review. Then every lid after that worked perfect, about 45 lids from a batch of 50. I attempted to order 150 more lids
and the place I bought them from no longer had them. Didn't know when I had it good. I should update that older post but if we can't get them what good would that do?
Edit: I posted a link to this thread back in that older review thread. But like I said they are (Finixa) presently unobtainable in the USA for reasonable cost.
