Tuxing txes062 pcp compressor

[DAVE BERRY]

Good afternoon PCP enthusiasts , recently purchased a compressor off e-bay. Looks good and works well. Is supplied with various spares foam filter inserts fuses assortment of O rings.
Takes about 10/15 minuets to top up 500/600 buddy bottle, now makes my dive tanks redundant. Dave

The lifespan of these compressors is a bit of a lottery. I bought the same model as you and it has lasted two years. It seems mechanically OK and I suspect a strip down and re-seal and replacing the non return valves may sort it out. For what it cost me I was quite happy to get two years out of it with no problems.

Got one, been great imho, no more messing about with bottle filling and testing plus I know its been filled with dry air from my dehumidified room.

Hi ,
This is a common misconception that if you source your high pressure air from a dry room that you will have dry high pressure air in your airgun. Just suppose that you are filling in the middle of the Sahara Desert your air humidity might be 10%. If you compress this air to 10bar this air will be at 100% humidity i.e. completely saturated. Continue to compress to 100 bar the air will be 1000% saturated and will precipitate out 90% of this oversaturated air as liquid water, continue to compress to 300 bar and even more water will precipitate out. Hopefully much of this liquid water will be expelled (expensive air compressors do) but this final warm compressed air will be saturated and when it cools will likely precipitate out liquid water in your gun. If you want dry air you will need to remove the water with molecular sieve under high pressure and not a “tampon”. My first air compressor was a Yong Heng air pump and although it could compress to 300 bar I did not put one molecule of air into my air bottle or gun until I sourced a high pressure filter packed with molecular sieve. Now I use a 4 stage dive compressor that outputs pure dry air having been finally dried in its high pressure molecular sieve/ charcoal column. Just my 2cents/pence answer.
Cheers and happy shooting

Many thanks for all your input , I will inspect the internals at regular intervals. Dave

I use the Tuxin V twin with the big Tuxin filter and it works well and i did have the small Yong Heng for about a year but it did take about 45 minutes to top up my 12ltr tank so i got the V twin . The only problem i had when i bought the Tuxin was the first time i used it was after about ten minutes after use no air was going into the tank, and the outhouse it was in was filling with smoke and oil was pumping from the crankcase breather. The seller i bough it from said i had to contact Tuxin this is when the fun starts after about 18 emails sending photos of the compressor and videos you find the warranty is not worth the paper its printed on .The last contact i had with them they told me i had to buy a second stage piston and i had to fit it myself , they could not understand when i told them there warranty was a load of crap. In the end after about 9 months i had a full refund from the seller , if you buy one and it work OK there good for the price i did buy another and it works well but the warranty is crap .If you buy one use a credit card not a debit card like i did as you get more help if you have a problem.

Hi Wilba,
The filter I used for my original Yong Heng 300 bar compressor was a Tuxing TXF003 L350mmxOD49mmxID36mm which can be found on that particular sale’s website. It will come with a repackable insert containing Mol. Sieve and activated charcoal (which is not necessary unless you are using it for breathing air- which I would not rely upon). For you to repack forget the charcoal and source some 13x Molecular Sieve “pellets “ which you must store in a absolutely dry well sealed container prior to use. When repacking make sure it is not loosely packed same as the original setup as you don’t want the incoming air to skirt around the pellets. Molecular Sieve needs to work at high pressures so don’t open the valve to the air bottle until about 2000 psi/160 bar. I add a few silica gel blue moisture indicating beads to the MS to indicate when the filer needs repacking; silica gel is nowhere as good as MS! A point to keep in mind is that the Chinese use M10 threads on their fittings which is close but not a replacement for 1/8 unf. However, Best fittings have M10 fittings to foster and using one of their fittings I installed a one way M10/foster so I could “blow down” and exhaust water from the compressor without losing built up pressure in the filter. But, remember you must be able to release pressure on the air bottle side(filter included) when finished. Also the foster fittings on the filter must be well sealed to the atmosphere when finished. A point to remember is that sometimes Chinese foster fittings are “ shall we see say not quite on par with Best Fittings”) I replaced my fittings on the output side of my compressor with Best Fittings including a micro bore air line. It is important to blow down your compressor regularly when running to expel as much liquid water as possible prior to the MS filter. Finally, this is important, the filter must be mounted in a vertical position, input downward and output upward.

Wouldn't it be safer to have to go through the hassel of using a large 12l divers bottle, filled up at a divers shop? At least you can be more sure the air hasn't got moisture in it, to pass on to all of your air guns? I ask this because ive always wondered to get one these cheap air compressors to fill a 3l divers bottle?

Good question echo1974 and this is how I started, but not for long! Keep in mind that you cannot use all the available air even in a 300 bar bottle; you are most interested in the “top bit” e.g. above for example 250 bar and above (fx air gun bottles are typically filled to 250 bar) so unless you have 250+ bar in the divers bottle you cannot fill completely your bottle on the air gun, but of course you can sit at the bench and tether the dive bottle and use it down to the air gun regulator pressure. Then you may to travel to have bottle filled, (£) and possible pay for inspection yearly. Also remember the dive bottle will warm up during filling and even if filled to say 300 bar will loose pressure when cooled to air temperature ( unless allowed to cool and then being brought back up to pressure). However, it still might be worthwhile if you have a low powered gun or do minimal shooting. I “chew” air with a 76 fpe Crown and a 150 fpe King so a decent air compressor works for me; circa 2 minutes 30 seconds to fill my 10 litre carbon fibre bottle from 250 bar to 300 bar. Anyway, just my 2 pence/cents worth.

Why i bought a PCP pump was i was getting my tank filled at a dive centre about 6 mls from me ,had my 12.5 ltr tank topped up and it cost £5.00 . At the time i had 2 rifles in with leaks but i had problems with both so i used up the air within 5 weeks . Went back to the dive centre and then had to pay £10.00 for the top up , but then when i check it at home the tank only had 180 bar in it . I then decided to buy a pump that was a good move ,as within a few week the virus hit the UK and without the pump i would have been stuffed . The dive centre never re opened after the close down and i would have to travel 25mls to get a fill now.

I think you can buy the Tuxin filters from Amazon and on the internet mine was just over £100 when i bought it.

Question: Is it a little risky filling from a compressor instead of divers air?
I.E - If filling a sml dive bottle or direct to gun using a compressor, is it easy to transfer moisture into the guns cylinder itself, if the filters are not doing the job properly, or have failed? How would you know about it, before the damage is done?

Hi Echo 1974
It would be a little risky filling with divers air if the dive shop had not checked their air moisture! But hopefully they always do as plenty of divers would complain! So they need to check and you need to check, simple as that. I have mentioned that you need 300 bar air for most applications and potentially the air you want is above 250 bar. Many dive bottle fills are only to a max of circa 232 bar and may not be of much use for guns that fill to 250 bar. I would certainly prefer to fill my air gun bottle from a pre filled source and not directly from even the size of the compressor mentioned above, most likely hard to control. As mentioned in a previous post I spoke about filters, drying agents, one way foster fittings on the filter cylinder and moisture indicating beads, it works well. Of course we humans don’t like spending money and perhaps never factor in our time, air quality filling our gun and perhaps the ramifications of wet air. Keep in mind wet air most likely will not rear its ugly head until the damage is done. In my case I have a functioning Yong Heng air pump which I upgraded but I know it will die sooner or later and likely when I absolutely need it! It’s now a backup for my 4 stage dive compressor; yes it costs money, guarantees fast dry high pressure air, very quick and since I’m not filling bottles from empty like a dive shop has very few hours on it. Low hours, excellent resale value.

Thats why i payed over £100 for a filter.
