Hi all, I'm new here and pretty new to the whole PCP rifle world too so I'm hoping someone can help.

I purchased a Reximex Accura rifle, 3 litre tank and a Tuxing ‎TXET063 compressor (the one with the display and auto shut off in May this year. All has been going really well until I came to fill my rifle and tank back up after a couple hours shooting at the range last week. The compressor keeps shutting itself off with the screen turning red and I noticed that the Amp draw keeps hitting the 42Amp limit. It also doesn;t sound like it used to when it starts to build up pressure.

Not sure whats changed with it as I've always been super careful when using it (changed safety temperature to 60c and only ever do top ups in 10 minute sessions) and it has given me no trouble when using it once a week for top ups. I have contacted Tuxing support but they have been less than helpful. I bought the compressor from Amazon Prime but they say it's not their problem now it's gone past the 30 day return window so I'm a little stuck as I can't afford to replace it after only 2 months of use.

I have reset the compressor to factory settings (as per support email suggestion), tried it directly in my house mains on the kitchen breaker with everything else in the house turned off/disconnected, changed power lead and it's always had 100% silicone treadmill oil used in lubing it after user (as per the instructions).

Here's a link to a video I took of it when it cuts out - Tuxing compressor

Anybody have any advice on things I may be able to check? Thanks in advance
 
At a guess, you are trying to get to 300bar? I don’t think these little things are really constructed to keep doing that despite the description. I suspect you are overloading it. I have the water cooled one, and don’t intend taking it above 250 bar fill on a 0.5l tank, again, in shorter fill periods like you. But I have only used it a couple of times so far, and the deficit in Mrs Berber’s holiday fund means I may have to wait a little longer for the tank, valve, whip, additional line filters/lines etc.

What does it sound like if it isn't under load ?

It sounds like it's trying to work harder than normal, like it gets a little slower and noisier. I was hoping the video I captured would help. The compression options on it allow you take it up to 400bar/4500psi so I thought I would be ok going up to 300 on the tank. The tank was initially filled at an RFD so it's only been used for top ups.

I'm a bit gutted now as I am in no position to buy a replacement and shouldn't really have to after only 2 months. I did pay by credit card and I took out the optional extra insurance on it too. Think I may have to cash that in to get it fixed or a replacement.

Sorry, the link is to my Google Drive where I stored the video (it's about 200mb mp4 file)
 
I'm no expert but it looks like you are pushing that little compressor beyond it capabilities?

They are really only designed for direct gun fills, not for filling dive cylinders, plus they can struggle when filling to 300 bar even though they are stated as being capable of that.

I have a similar one (Nomad2) and only use it for filling guns, and most of my guns are only 200bar. I had a 250 bar, and it would noticeably take longer and work harder when filling that gun over 200 bar.
I also had a very small 500cc 300bar carbon daytripper bottle, and my compressor would fill that, but again it would be noticeably slower and you could tell it was struggling after 250 bar.
So IMHO you may just be pushing it a bit too far trying to fill a 3 litre dive bottle and/or 300 bar guns.

Not saying they will not do it, they will, but you are really stressing them by doing that.

If you have a 300bar gun, try just filling it 200-250 instead of to 300?
Most pcp's have a "sweet spot" and its usually lower than the stated max fill pressure.

If the compressor is only two months old, you may be able to claim a repair / refund, as under normal circumstances a compressor should be expected to work ok for longer, but if you have told them you have used it for a dive cylinder, that may be a get out clause for them to use? As above if the seller tries to cry off, maybe get credit card company involved....

Hope you get it sorted....
 
It should have a one year warranty? I have one fills 3l bottle no problem the last time 190- 300bar and didn't go past 36 degrees on temp, I did get the one that specified can do 3l tanks though. I would definitely push the warranty card with amazon if it is only 2 months old.

Talk to your credit card company.

Whose optional insurance?

Read the add you bought it from for the specs of what they have stated it is capable of. If they have not stated a volume limit then you are golden for any claim.

You have to be careful with advertised pressure numbers. Is 400bar the working pressure or test pressure for example? When looking to buy, the test pressure is sometimes 100bar to 200 bar above the working pressure. I am assuming as you mention both 300bar and 400bar, 300bar is the WP. As previous, I wouldn’t go there on a budget thing like this and expect it to last.
 
Test pressure or max pressure is usually 1.5 times the actual working pressure, so for example with HPA rated for 300 bar working pressure, they should be tested to 450 bar.

Thanks for the reply, I guess it makes sense but I am a little gutted that it is pretty much advertised as such and I thought I was using it well within it's limits (I tend to try buy bgger or better than what I require, just for the breathing space).

I only ever fill the gun to 230-240bar but it struggled with that too, with the Amp draw hitting it's limit a few times. Seems mad that they can allow up to a 400bar limit on the device (and the page listing on Amazon) but it gives up so early.

I've just looked at the ad again and I clearly missed the bit where it says this:-
Home 110V/220V / Car 12V Battery: The portable PCP compressor can be directly powered by a 12V car battery outdoors or a 110V/220V socket at home. It is very convenient to fill your PCP air gun or paintball tank anywhere. The maximum inflation tank is limited to 0.4 Gal/1.5 L. A 0.5 L tank will take 18 minutes from 0 to 300Bar and 5 minutes from 200 to 300Bar.

I thought I did the right thing getting it filled initially by a pro and only topping it off (I'll be honest, my mate uses it more than me due to the tank on my gun being pretty big and his being tiny, I rarely have to top my gun off while out shooting).

The insurance was with Protectmybubble (I think) via Amazon, it was offered to me when making the purchase. Think I'll try putting in a claim with them and just play dumb
 
They're incredibly simple little things and when used within the expected parameters are pretty robust and spares are readily available.

Yeah I checked out spares and things along with repair guide videos for this but not sure if I should be taking it apart to try a service with it only being 2 months old

I mean you've been pushing it well past it's design limits so really that's on you. Id try a few direct rifle fills and monitor it.

Get a decent video of it running under no load and one of it loaded up lets see if there's something obvious amiss. Chances are it's been burning up the lube internally

I wouldn't have thought I'd been pushing it that hard though. I know I used it to top off a larger tank (my mistake, I missed that bit on the ad) than it suggests on the ad but aren't the design limits based on how hard the compressor itself is worked? As in using it for way longer, running it hotter or putting it under more pressure than it supports?

Even if I was to connect it to an empty tank and use it (which I would never do), surely it should just chunder away with little to no feedback pressure until the tank was to get close to its limit. I'm no engineer though so I'm not saying I know exactly what I'm on about (I work in IT) but as I haven't pushed it above 3/4 of it's total supported output pressure and only used for very short periods, I would have thought it would have been ok just topping off a 240bar (from about 180-190) fill on my rifle and a 300bar (from about 230ish) top up on the tank.

I'll try grab some videos now

Here is a video of it under no load - https://drive.google.com/file/d/1Yqk1ZfnolmT4Xx3ocSrILsDnof6ATOVv/view?usp=sharing

And one with it connected to my tank again (which was at 280bar) - https://drive.google.com/file/d/1DaGBZquWjN8_ANeIkKYfEeAGaokR3qpM/view?usp=sharing
 
I know this is unlikely to be of much help to you but I had exactly the same thought process with my Chinese compressor and did exactly what you did, and my compressor is exactly as dead now.

I salvaged what I could. That's all really I could do.
