(Carette 4500PSI Air compressor）
The estimation for the high quality compressor designed for homes (Carette 4500PSI Air compressor）

That would be just selling it with free shipping, nothing at all like a supplying for testing to prove their product quality. No. If that is the “offer” it is effectively no different than just selling the units. No way would I buy and guinea pig another unit. My Mrodair loss, I chalk up as the cost of for a noobie becoming a useful member of TAG.
Yeah I do drain my tanks to about 30-35bar below that the booster efficiency goes way low. So pmv is a must! It’s cheap and simple device so I’ll say it should be on every filter tower period.
I just bought the coltri head used and abused and been looking in to these compressors for a good long while. I build my booster from barstock for commercial ones being rediculously over priced for how simple they are.
I have started to build similar v 2 comp around a year ago but been busy to complete it. And now I found a bargain used coltri mch6 with busted fourth stage it’ll be even longer that I will finish it.
Everyone should have a booster out in the field, you can really pump those tanks low, and not to fill almost full tanks.

Some people just don’t know what they are talking about. Or they believe the snake oil that some salesman trying to sell and believe it to be true.
The crankcase looks just like the Airmax and we all know it doesn’t have rod bearings.

Marko you say PMV Is a must?
Do u drain your tanks below 1800 psi then refill them?
Please back up your statements with some facts…
Here is the info from the manufacture on one of the most widely used pmv’s.
http://valvesandregulators.aquaenvironment.com/Asset/1308_OM_1310bpr021127R.pdf
In there it tells you….
“The regulator will improve moisture separator efficiency and filter life as much as 450%. This is done by maintaining pressure in the separator and filter at about1800 PSI when tank pressure is lower”
Once the pressure is above 1800 psi it flows free… as if the valve was not there.
So for airgunners… it’s like tits on a bull.
I wouldn’t say it’s a must unless your constantly filling from below 1800 psi.
Now the good thing though is a PMV Is cheap.. well in the grand scheme of things (like 60 bucks)
And can be added in when ever..
Just curious as to where you hear it is a must.

Looks interesting, pmv is a must but discs or over pressure valves between stages not so much. Don’t see any in coltri or komptec. But final pressure release safety would be needed, does it have that?
I wouldn’t be overly concerned about the rod bearings, have been running that kind of v block compressor for years, and at one time it ran for two days non stop as our atlascopco was waiting parts. It didn’t suffer much from that, it’s still going strong.
Piston and cylinder design would be nice to know. I have nothing against Teflon rings, looks like even some of the big manufacturers use them also, I know coltri does I have one on my table waiting for bearings.

If that is actually what you are asking, you are very foolish, very brave, or very confident.
This guy has posted on several websites, I got this from googling the compressor name. This is the only thing out there on this compressor.
Anyway – from “translation” on one of his posts I took it that he wanted to ship the compressor FREE to people for “testing”, but I think the “shipping” was free, not the compressor. SO just pay $980 and he will ship it free for testing……
Wonder how they came up with 2000 hrs, that’s 2.5 months running 24/7 but seems like they just came into existence 6 days or so ago.
sincere, guykuo would be an excellent reviewer of your compressor, he has proven his ability to provide a detailed look at previous compressors that where brought to the US for the air gun community. If more than one unit is to be tested, I would like to put the Carette 4500 to the test with multiple users at our local club.

Are you asking if I would evaluate a unit? Yes, I would be interested doing a thorough test, but only if my findings can be posted here at TAG for all to see. The good, the bad, everything I find would be reported without prior editorial approval.

Would you please come to evaluate this Machine Translation
Some images of the filter and water separator internals would also be useful. Where is the final stage filter? I see the mechanical water separator on the photos. If we could see the mechanism for droplet separation and how the drying media is contained it would help use understand the design level. Is the media contained in a non-corroddable inner sleeve? How much molecular sieve can it hold? How much water can be in the separator before it reaches the drying media? Those are all details of interest.
I would like to ask you to evaluate this air compressor, is interested in it
I know you used Mrodair’s experience,
For a while I take a picture upload
Can you post pictures of the pressure maintaining valve (aka priority valve). I didn’t see on in the video. I only saw an output whip attached directly to the separator without an intervening PMV. What we mean by PMV is a valve that remains closed, and prevents air output unit pressure has built up in the waters separator and air drying filter to a release pressure. If a PMV valve is present, typically no air exits the separator and dryer until at least 1600 PSI. Where is it?
