VEVOR 300 BAR COMPRESSOR REVIEW

[@pete7894]

I bought one of these and this was my experience with it. I direct filled rifle tanks without issues never more than once every half hour. When I started to fill SCBA tanks that did not go so well. I ran it straight for about 20 to 30 minutes and that melted the 2nd stage piston rings and no longer could get past 3000 psi just like that. I contacted VEVOR via online only and followed instructions and answered all questions, within a few weeks VEVOR sent me out 2 new sets of 2nd stage piston rings free of charge. I installed new piston rings, and the compressor is now working properly again. 1st stage rings were fine. To VEVOR, I recommend that an extra 2nd stage piston ring set should come with unit as mine did not, this would have left me more satisfied with this purchase and reduced stress. To users if filling tanks, I would not run straight, I don’t know what the magic number is, but run to long and it will melt down no matter what you do. Some say 20 minutes, I will never run more than 10 minutes myself between cool down periods is my plan going forward and no more tanks for this one. Also, this is not a “Yong Heng” and parts are not the same. Parts for this one must go through VEVOR. Patients is a virtue here, Ha.

Parabéns a YONG HENG pelo projeto tão exitoso e de sucesso, os demais são cópias melhoradas ou não . Recomendo a todos para maior durabilidade da unidade de compressão, antes de desligar o aparelho fechar a torneira do tanque, abrir as duas válvulas de eliminação de umidade para só depois de um minuto, desligar a unidade, esse procedimento evita o calço pneumático da pressão do sistema no cilindro e segmento do compressor.

[@kmom777]

First I was a bit skeptical about the additional metal sheet cover on the front but then from the known failure in other brand Yong heng I realized this metal cover actually act as a safety sheald in case of something flying around so it's not bad to have some additional safty.

[@markusscholl4958]

Nice presentation as always. I had a Hill compressor and after 2 returns for repair (leaking, no pressure built) I sent it back for refund. Depending on how intensive the individual shooting with airguns is, I recommend to invest into an high quality compressor. Since I have a Bauer Pe 100Tw there are no issues anymore. It fills the bottles very quick without having the need to cool with water (Hill is also air cooled I know). The air is also already filtered and dry.

[@Airbuks]

My Hill still runs strong every week with no problems 👌 that Bauer is a very nice compressor but also costs a nice penny 😉

[@wolw66]

Great review 👌 This looks actually nicer than the original (Yong Heng). My Yong Heng is on its third year now. Change oil every ~1 hour or when the oil starts to turn grey. Add a an additional desiccant filter.

[@Airbuks]

Yes indeed it looks nice . Mine has run now for about 3u and works very good . After the video I changed the first oil as it turned grey but now still looks pretty transparent

[@Engineer9736]

I just ordered this compressor. It's just difficult to find the right adapters to connect it to a DIN scuba tank. I see many DIN 300 bar to 8mm quickconnect adapters with manometer included, but i believe the 300 bar DIN connection is different from the 200 bar connection. I asked the ebay seller about it... waiting for response from them.

[@Airbuks]

There are some adapters available from 300-200 but I don’t know if they exist the other way around? There sure is a solution

[@XazaxAirsoft]

Is there a way to drain entire system? Other pumps have drain screw to let go excess moisture. Or do you have other way of doing that?

[@Precisionriflesireland]

Great video as usual. I will take a look at that compressor. 🍀🇮🇪💪

[@Airbuks]

Thx 👊

[@jeroenvandal5238]

Is it good? I want one? But works it wel?

[@ipissed]

Make a connection to the tap and just run cold water through the pump then out the drain. It costs a nickel but it cools better and eliminates a failure point.

[@Airbuks]

Nice tip 👍

[@PaulHamM3]

I alway been told to bleed off the pressure first before turning off the compressor, get yourself a best fittings one-way valve and that way you can bleed off the compressor and shut it down without loosing air out your bottle.

[@Airbuks]

Yes the one way valve is a very good extra option I will still need to buy . Regarding the bleeding off . I also have the EC3000 and stops at 300bar automatically ( some budget friendly ones do that aswel ) keeping the system under pressure just like shutting the comp of before closing the valve . I have done it like this and never had any issues

[@PaulHamM3]

@@Airbuks for as many people who say never to turn it off under pressure there are the same amount who say to bleed it off then switch off but whatever, i had a yong heng for three years and not had any issues but eventually the water stopped flowing properly, turned out the system was blocked so i bought an entire top end and now its like new, i put calgon in the water bucket now.

[@jamessheffield9415]

Good Morning, Any idea if or when these will be available in the US? I tried to order but USA is not an option for shipping…. Thanks for the great video😊

[@Airbuks]

Not sure but I will try to find out 👍

[@KESDtv]

I'm curious to know if this Vevor branded compressor has the same high pressure piston as the Yong Heng. The Yong Heng has a brass piston (with 3 o-rings) recessed into the large low pressure piston vs clones have a aluminum piston with one cup seal butted up against the low pressure piston. Would you mind taking a look inside?

[@Airbuks]

Interesting 🤔, but this one is still running great without problems so I don’t really wanna open it 😉

[@pete7894]

I would no, not the same. I melted my 2nd stage piston rings down in two weeks of use so i got a look at them. There are not split rings, they are thinner that Young Heng that i can see, the intire 2nd stage piston is different shape and contours. I am desparretly looking to soucre new ring direct from somewhere as thius will be an ongoing issue i am sure. These are like a plastic ring with no ring gap or split.

[@JohnDoe-es5xh]

This is also a good compressor to fill up modified fire extingusher tanks.

[@Airbuks]

Modified fire extinguishers ?? To do what ? Fill to 300bar ?

[@pedroluqueyuste3]

Hello, I have been watching your video and I would like to ask you a question, I want to buy a compressor but I don't know which one, can you tell me what you think of the Vevor compressor, and which one you recommend, I like the Vevor and the Tuxing TXES021, I would really appreciate your opinion, greetings Pedro Luque from Spain.

[@Airbuks]

Everything depends on the budget 😉

[@teamchampionfeed]

Toch handig apparaat! En zag ook niet al te duur, ben zelf ook eens aan het rond kijken voor ene. Maar dan iets compacter en wat op een auto accu kan draaien! Bestel je deze bij de fabrikant zelf? Grts uit heist op den berg

[@eclipse2260]

I have only problems with mine, first it threw the fuse immediately. The ground wire clamp stood against the windings because it was tightened without looking on it and turned around and made a short circuit. I fixed that. Than at the first fill the safety valve list its functiins. Now the pressure only raises up to 120 bar. The customer service is very slow. I think about giving it back

[@Airbuks]

🤔 interesting , mine is still running fine but I did got it straight from them as a review product and they might have send a unit that was tested. But that isn’t a excuse to send you a faulty one ☝️

[@pete7894]

Your low pressure issue is most likly 2nd stage piston rings melted down like mine. I would love to know where to get or source parts directly ?. These are not the same as Yong Heng.

[@eclipse2260]

@@pete7894 it was Not the piston. In the Tube that is screwed in to the top end where the piston moves, there is a disc that you can reach if you Heat the Tube and Turn it out. It is Like a high pressure valve that seals Ruhe second Stage. The disc is to thin and blew out on me the third time now, before i could totaler thf disc Like 90 Degree or so but it is Always blowing out over 280 Bars or so

What oil did you go with? Also, did you know that there's a one-way check valve that you can get oh and you should consider a oil water separator air filter. they are expensive but i guess you should use one according to these other guys that use this type of Compressor congrats on surpassing 20 K!

[@Airbuks]

I use a synthetic compressor oil that was advised by my local compressor shop . Sinds the recommended oil in the manual isn’t available where I live they gave me a equal replacement Regarding the separator I have on my other compressor 😉 but I wanted to show it in the video as it comes out of the box , but I meantion a few times that you should use a extra filter

[@Tillice]

Hi! Friend has one of these but its having some issues. Its brand new, and only fills a tank to 1000PSI. any chance you know why?

[@Airbuks]

You might wanna check if you have any leaks in the connections or another possibility is that the piston is fried and can’t buildup enough pressure

[@Tillice]

@@Airbuks thanks for the reply, some..... "percussive" maintenance apparently got it up and running. he accidentally dropped it and heard something seemingly get dislodged lol.

[@k.w.3620]

Hello, it's been a while since the video... One question... I have the same compressor. Is it normal that the red valve always releases air intermittently at slightly higher pressure? Maybe someone knows an answer?

Hola, podria llenar un tanke de 7 litros para PCP a 300 bares con esta bomba ? ... aunque en sus especificaciones pone max 6.8 litros ... Muchas gracias.

[@gheorgheungureanu3559]

... seria desde unos 100 a 300 bares ...

[@Engineer9736]

Personally I would put the whole setup in a separate room, with a camera to watch along and such electrical socket to cut the power remotely (or get the model with the automatic cut-off function). If 300 bar explodes you're in the hospital........... I'm curious how maintenance is managed with this compressor. Can you send it to the manufacturer to have it maintained or so? Or you just use it until it burns out?

[@fredrikcarlen3212]

You have to replace the oil every few running hours, takes a few minutes and you're good to go. Pretty much every part can be ordered, but delivery times will be kind of long. They're really easy to work on, very few moving parts to this thing..

[@Bruno-der-Problembaer]

Hello, I want to fill a diving tank with the compressor. If I use a carbon filter, is it safe or will water and oil still get through?

[@steveh8724]

Definitely DO NOT USE to fill a diving tank! Even if YOU aren't going to use the dive tank air for breathing, someone else might. This cheap compressors are iffy even for PCP airgun filling. Using one for SCUBA is a terrible idea as they DO NOT HAVE the quality components and filters to ensure safe air is all that gets into the tank!

[@hilavich]

How long does it take to fill a 12L 300 bar bottle from 200 bar to 300 bar ?

[@Airbuks]

It’s advertised to max fill a 6.8L bottle 😉

[@hotchihuahua1546]

These types of compressors can be dependable if maintained properly . They are not like a regular 120psi compressor for your shop. Get GOOD full synthetic compressor oil and change it out frequently . 4500 psi vs 120 psi , you get the picture . Liquid cooled is the way to go ! I like to leave the room when filling those big tanks to 4500psi , just in case . Lol

It’s a nice system if maintained well and for the money you can get some extra freedom not having to go to a scuba shop to fill

[@arcticairgunner]

Scared the heck out of me when you released the pressure 😂

[@Airbuks]

🤣 sorry about that

[@RobertRothhaar]

I own one of these compressors and aftera few years it started leaking air into the upper cylinder water cooling jacket. Tried to use vevor customer servive to buy repair parts. I gave the customer service all the information I had about the unit as there is no model number or serial # on the pump. I even sent them a link to their website showing the pump. I was told they could not confirm my pump without an order number. I bought the pump through Walmart so I dont have an order number. Customer service went round in circles about the order number that I told them I didnt have till I gave up. Now I own a useless 25 lb vevor paper weight. My advice to all is dont buy from vevor you will regret it in time!!!

[@henrymoreland8719]

[@shiz8048]

Do not use tap water as a coolant! Tap water in many areas contain metal ions. It will corrode your compressor·s aluminum head .use the car coolant and put in a bucket. You can also add ice cubes isolate from coolant in the bucket, or install a water tank cooling device.

[@Airbuks]

Thx for the tips , I am very aware of those things but for the review I wanted to bring it exactly as it’s written in the manual. The water in my house is filtered,softened etc and I blow the channel out after filling. But I have seen people use coolant. Ice in my case wasn’t necessary as the temp never got above 41degrees during the 25 min fill

[@AirRuna1]

A pinch of baking soda in the water will neutralize any acids if you don't have any auto coolant... four years on my yong heng and no sign of any corrosion ...it on average runs twice a week, coolant is way harder to depose of too!

[@Airbuks]

Awesome tip thx 👍

[@johnb5519]

If I was just filling my gun with it, I would just run the tap water straight through it and not risk trouble from the small pump possibly quitting.

[@Airbuks]

You can do that but I would advise once you are done for the day to blow out the cooling lines with compressed air

[@johnb5519]

Yes,, good idea for sure.@@Airbuks

[@KevinWood44]

WOW very affordable Unit. Typically this is the hidden cost of shooting a PCP air gun (well worth it though) I have unit that does not use water or oil (it is the model that Talon Tunes and Air Marksmen rebranded....I know NOTHING about air pumps...is there a benefit to using a unit that uses water/oil? Regardless, this unit looks like a steal for the price. Lots of people are going to jump on this

[@recklessjunkie]

Yeah, it’s like how a cars engines cooled But instead of coolant its water it’s like the best way. these things get extremely hot. you really should use a bucket of ice water. Thats what I’ve seen others do.

I would have to pass because the price seems too good to be true and there is no dealer network to fix it. The Umarex ReadyAir was my last cheap compressor purchase. When it dies again, I'm buying a real compressor.

Ya all the parts are not same as yong heng, if it burns up you must have patients for VEVOR for parts.

You should NOT stop the compressor before releasing the screws on the side. Add one way valve on the tank side, then close the tank valve, release the pump screws to release the pressure inside and then switch off the pump.
