NTM Vevor Compressor
« on: December 24, 2018, 05:04:39 PM »
Last week I posted a WTB in the GTA classifieds for a YH compressor. My MRodAir MKII is down needing a high side seal due to a minor mishap with quick connectors. So I reached out to see what was available to fill the gap. I also wanted a small portable compressor for road trips. Aluminum tanks are a bit cumbersome and carbon fiber tanks are too expensive.
Randy_68 responded lickity split with an offer. Seem his Uncle had a Vevor, a Tuxing with a spare top end and an MRodAir like mine. He wanted to sell the smaller ones. We struck a deal on the "used only once" Vevor in the original box for $220 shipped.
Bought on Thursday and FedEx delivered it today, Monday.
I asked that he drain the oil before shipping and he did. I had heard of others having issues with the oil ending up in the top end during shipping and wanted no part of that. I ran down to the local Auto Zone and grabbed a qt. of synthetic 5wt oil.
Got home and unboxed it. All original packing and every included just like brand new. Basically bought a brand new compressor that had been tested.
It's a cool 65* here today so I figured I would just set it up at the shooting bench and try it out. I grabbed a 5gal bucket of water and made all the connections. The only cord I had laying around was a 100' extension cord and I figured the compressor and water pump would draw too much for it to work.... what the heck, give it a shot. I put a dead head in the fill hose and fired it up. Good thing I was watching because it went to 3k in like, 5 seconds.
Sweet !!! Lets grab the Urban.... Oh darn, the Urban is topped of from the last shooting sessions.... Oh wait, I got an SPA Varmint that has a 2 day leak, let's grab that.
Hooked it up and 20 seconds later it was at 3k and I shut it down. The temp gauge read 38c. I unscrewed the bleeder and virtually no moisture came out.
All and all, it's just what the doctor ordered. The carry handle makes it the perfect "PCP road buddy" for trips to my sister's and anywhere else I may go for airgun get togethers.
I will only fill guns with this compressor and with 15 to 20 second fill times I'm pretty sure a 1 gallon water source is all I'll need... even if I have to refill the jug every few fills.
No auto shutoff or other whistles and bells, just a slick little PCP air source.
Happy Happy Happy
Merry Christmas ya'll.

Well, after shooting and filling the Urban until I got bored due to accuracy I decided to bring the SY Sumatra .25 out for a few spins around the dance floor.
If I thought it would be more of a challenge in accuracy I was way wrong. But that's a story for another thread. This one is all about the "little compressor that could".
Between the two guns, I filled from 2k to 3k at least 10 times. Not even so much as a hick up. I ended up testing my theory on the lessor volume water source. I had a 48 oz. (3 lb.) plastic Folgers container. I cut some holes in the lid to run the hoses and power cord for the pump out of. Over the course of the shooting session the ambient temps outside went from low 60's down to around 50ish.
I just let the pump run between fills. Like I said,  filled 10 times <> between the two guns from 2k back up to 3k. The highest temp on the compressor read 46c. Between fills it dropped down to 26c.
I bought a fahrenheit temp gauge online for the MKII but I think I'm gonna put it on this little guy.
The paperwork says max fill pressure is 30mpa/300 bar/ 4500 psi. This one is a set pressure type (no adjustable shut off). I'm not sure what the factory set it at but it don't matter to me because I don't plan on ever pushing it past 3k to only fill guns directly. My MKII is for filling tanks.
Filling the Urban from 2k to 3k took an average of 16 seconds and the Sumatra from 2k to 3k took an average of 22 seconds. I did fill the SPA Varmint once from 0 to 3k. That took about 25 seconds. In 3 hours it leaked back down to about 900 psi so I'll need to replace an oring or 2 in that gun..... or just sell it.
At the end of the session I looked at the color of the synthetic oil through the sight glass and it looked just as clear and at the same level as it did when I filled it.
The compressor never once struggled to perform, even with the 100' power cord. I never once got the feeling I was pushing it to anywhere near it's limit.
I've read the horror stories about this compressor and I can't help but think..... if I don't ask it to do anything but fill guns, change the oil regularly and pay attention to temps (replace water when needed) it should continue to perform and be a dependable air source.
We'll see.

Swapped out the Celsius temp gauge on the Vevor for the Fahrenheit temp gauge I bought awhile back. Some folks reported the being a bit larger and had to modify the a bit. Mine was a drop in fit. Just had to pull the cover off of the unit to get to the underside and release the tabs of the original one. The sensor pin was the exact same size as well.
 I don't naturally do Metric or Celsius. When I was in school we studied gozindas/arithmetic, not math.
Works great.

I've had a Vevor compressor for about a year.  It's the set the pressure model and have only used it for fills direct to guns.  I'd say I've over 300 fills to 3000psi.  Never had an issue except it tends to get dirty and eventually clogs up the hose as the Vevor has those small white seals at the compressor outlet and the hose oil/water separator inlet.  I got a second Yong Heng hose with oil/water separator and has much larger air passage in the Delrin seals.   After you use it awhile, you can tell by sound and performance if it's time to take a peak.  Heard a lot of unhappy users of the Vevor and wondered what they filled and how long the run times.  I just change the oil regularly and plan on tearing the whole thing down for a cleaning and a look see now that it's been running for a year.  Enjoy and good luck!
