I just purchased a Wlater Kiddie compressor but it has at best marginal filters on it. These look perfect for it. So, overall , you would recommend them?
Hi Herman,
- I feel unqualified to actually "recommend" this filter system... I got so much negative response to it from the ScubaBoard. "Cheap Chinese Crap"... and similar comments, it sort of blew my confidence. Hard to tell if the biggest detractors really know what they're talking about or not. And, I didn't send the filtered air off for testing so I can't say it gives "E" grade breathing air. At the same time, I can't see any reason why NOT to recommend it.
- From what I've learned about the filtering process (as an amateur), the system makes just as much sense mechanically as other scuba compressor filters. In fact I've seen older scuba filters that are nowhere near as smart as this system. And when you add in a Back Pressure Regulator or Pressure Maintenance Valve... It's MORE efficient than vintage filter systems that lacked those features.
- I filled scuba tanks many, many times through this filter system (30+). I dove with and breathed that air and didn't taste nor smell anything funny (yes I know CO doesn't taste or smell). And, I monitored the blue test strip in my filter. Moisture and oil came out of the condenser in significant amounts. All of the remaining air passed thru the filter media... So it HAD to have been filtered just like any other filter tower.
- I currently use this Chinese filter system on my RIX SA3. The RIX already has two condenser towers, so not much comes out of the condenser. But all of the RIX "Sweet Air" is going through the filter tube and I monitor the blue strip to be sure I always have sufficient filter capacity remaining. In other words, it works fine for me.

I saw the posts on scubaboard and wow some guys are just plain asses. Good for you for giving it a try and posting results. I have the same oil water separator on my system and it works well. The aluminum is very thick and machined well. I'm sure the grade of aluminum is not as good as others but because of the small size it is plenty strong. I have put 3300psi through mine with no issues. That is all my compressors will put out so far. I don't want to push them too hard. Thank you Surflung for taking the time to post all the info and pictures on these, it is appreciated.

Now that they are on amazon(chinazon) with free shipping, the price is right. But this guy having one explode makes me rethink cheap.

The TUXING filter is a different system than what I reviewed. Its an in-line filter between air source and airgun. It doesn't have a moisture drain, for instance. And apparently it has had problems in more than just the above instance. There's quite a lengthy discussion on a different incident at Airgun Nation... At least some of it blaming the Chinese compressor for not having a moisture condensation system.
https://www.airgunnation.com/topic/tuxi ... ent-wrong/
In the Airgun Nation instance, it appears the plastic filter tube ruptured inside the exterior aluminum casing.
In YOUR instance the exterior aluminum casing ruptured... Circumstances not given.
I don't think they came to any conclusions on the exact cause in either incident... But again it isn't the same thing as what I reviewed.

The 2-tube system I configured and reviewed here is quite different from the TUXING Tube (above). It's almost identical functionally to the filter tubes on Coltri Sub and MaxAir35 IMHO. It all looks well made and well thought out but aside from that, there's no way to know if the aluminum its made from is bad and might rupture. When you buy a Scuba compressor filter system from ANY source, you assume it is made to function safely in the application for which it is sold. To say, "Well, I have one and it didn't blow up in my face" is to deny your up front assumption that it isn't supposed to blow up in your face. If that's what you are testing, you should be using a hydrostatic testing facility. And maybe that's what is needed to be certain they are safe. Are other systems Hydro Test certified? I haven't seen that if they are. The 2-Tube system I reviewed was rated for 4500 psi.

I have to say, the initial attraction to the Chinese filters was price. But in my case, I think the original cost was about $200 for the 2-tube set. Then, I spent a fair amount of time and money experimenting with connecting hardware to adapt it to my compressor. And then, I had to come up with a modified filter housing so I can change filter media. Bottom line in time and money, I probably have around $400+ into getting it all up and running. And frankly, you can buy a lot of confidence in a different system for that kind of money... Compressor Stuff, Jim Shelden, American Airworks... Those guys can come awfully close to the same overall cost with non-Chinese filter systems.

Hi SurfLung,

Thank you for the update.

It so happens I have an offer for an item similar to the set you bought and tested. However, the item I'm hoping to get is just the moisture separator half of the kit. I would like to know what adapters I'll need to convert their fittings over to US threads. Also where to purchase them.

Thank you,

Couv

Hi Couv!
- Yes that moisture condensing tower is a pretty impressive design. As for the threads, it may depend on what the unit is set up for... I've seen some set up for quick connect airgun use. Mine was set up for a britsh thread BSP 4 (aka G1/4) thread and I eventually used adaptors to make it JIC 4 (aka AN4)... These I think I got from a racing supply company:
https://www.pegasusautoracing.com/produ ... oduct=3252

Umm... Actually that might be just the outlet adaptor. For the inlet I'm remembering I found an adaptor from BSP 4 to 1/4 NPT. But the BSP 4 end didn't have an O-ring seal. I think I sealed it with red loctite. I can't remember where I got the adaptor.

I'm sorry I can't find where I got the G1/4 to 1/4 NPT adaptors. Might have been on an Amazone search. :cry:

Thanks guys. Bottom line is I'll be converting from British standard to a US standard-not some oddball thread to start with. When the moisture separator arrives I'll sort out the adapters.

Cheers,
