Those with a Tuxing 2 cylinder compressor with auto purge - at the end of the fill cycle when auto purge activates, does it expel a lot of moisture like mine does?
Tuxing 2 Cylinder w/Auto Purge

I do not have auto purge on my Tuxing 042, but when I manual purge I don't get that much. Does your model have dual gold filter towers?
So, I understand you run 25 minutes straight to fill your 88cf tank? What max temp do you see and what are you using for coolant?

I'm using 50/50 premixed automobile coolant and it never gets over about 60C/140F. Yes, it has the dual gold filters.

Depending on humidity in the air, and temperature will depend on how much moisture you will get out of it.

You’ll be surprised how much moisture those filters can get out of the air at high pressure.

Local conditions and individual compressor system "plumbing" can make a fair bit of difference, I would think. My Tuxing 041 didn't come with auto purge or the dual filters. I've added a coalescing "filter" followed by a molecular sieve desiccant filter unit, so it's likely similar to yours. I have to purge manually every several minutes, so I don't see the cumulative "all at once" moisture output that you're seeing, so it's a little hard to compare directly. However, I would say that the goal is to spit out more moisture rather than less, so your system is likely fine.

I have a mch 13 and i fill my 88 cuft. from 2200-4500 in about 6 min. Its over 8cfm and it probably dumps more than that.

Well, Alkin says every 10 minutes, which it doesn’t get to for a top off, so I purge at the end, or about 7 minutes. 50% humidity where I fill, and not much water during a purge, maybe a tablespoon.

MCH 13 is a Coltri brand compressor, up size model
the water drainage from your Tux is normal

I am thinking about pulling the trigger on one of these Tuxing 2 cylinder units. Looks like you have had yours for a few months. Curious how you experience has been outside of the service issue you first experienced. Would you buy again? Thanks in advance.

Moisture expelled is always good. This is the moisture that did not end up in your tank/gun.
IMO the Autopurge feature on Tuxing compressors is a total gimmick as it only activates once, at the end of the cycle. It really needs to be on a timer to be useful, and activate periodically during long fills to expel the accumulated moisture, every 5-10 minutes or so. I just purge manually on long fills.

I eventually “forced “ Tuxing to take it back because of their poor practices. I wish it had worked out differently because I think it’s a good value.

Thanks for getting back. Of all the black hole hobbies Ive gotten into I believe the whole (which compressor to buy) question in Air gunning has been the toughest. I have been researching and reading for a week now mainly on this forum, which has been a god send BTW, and it looks like the best advice has been a post from a member DeadonShot 2020. I have pasted it here.
I think there three categories of PCP compressor buyers:
1. Buy cheap and throw away when it breaks, or repair it yourself.
2. Buy mid range and hope you get a good one and repair it yourself if and when it breaks.
3. Buy top end and hope that for all that money it runs and runs and doesn't break. If you have that much money to spend you can probably either afford the shipping to send it in for repairs or pay someone to fix it.
Do you mind telling us what you ended up with? As a fellow Texan I'm curious.

How about all three, and then some since 2017?
- Yong Heng clone single cylinder - lasted a couple months.
- Tuxing two cylinder - worked good, modified to add my own cooling system, gave to a friend when I bought:
- 110 vac Daystate (Coltri) compressor - lasted about a year of weekly use (3 or 4 top offs per week), couldn't be fixed by the Coltri rep in Oxnard (PS., if your Coltri isn't under warranty the labor rate is over $100 per hour for compressor work).
- 220 vac AireTex Compressor, which is a high-quality clone of the Bauer Junior 2. Have had since May 2020, has worked FLAWLESSLY since that time with over 30 hours run time. Doesn't sound like much until you realize it take 6 or 7 minutes to fill (top off) a 45 min (66 cu ft) SCBA tank from 200 to 310 bar.

My first compressor was in the first category - a Yong Heng. It started having problems and I needed something quickly so I got another one. At that point I decided to go the middle route and got the Tuxing. Had a problem and returned it. Actually ordered a Coltri MCH6 when they were on sale but cancelled the order as I needed to buddor other things. I recently started to work on the original Yong Heng just to see what was involved. I realized how simple they are and have parts on the way now to fix it so I’ll have two functioning units. Decided to stick with the Yong Hengs for now since most issues can be fixed for $30-$40 - a lot of it goes back to what you plan to do. I have a 9L carbon fiber bottle that I use down to about 200-250 bar then top it off so it’s not very hard on the compressor. I also have a good setup for cooling so I’m sticking with these instead of spending 10 times that for a mid to high end compressor.
