Vevor water cooled, looks like a GX CS4 clone...

[like.2.fly]

I see that Vevor now has a water cooled model that looks and sounds very much like a GX CS4, but for about half the price. Has anyone tried this one?

Vevor has decent stuff i have an air cooled shoebox compressor that still works fine. They just came out with a twin cylinder shoebox compressor. Its twice as fast as the single cylinder. There's a youtube video.

I'm always curious about these types of things, but the problem is that it's almost impossible to see the insides.

Like you, I am wondering if it is a CS4 clone, or maybe a New Warrior like this?

These are a Yong Heng clone that seems to work very well, but not like the CS4.

 

[gendoc]

is there a place to grease the connecting rod and other places on the clone of the cs4 ?

There doesn't appear to be a grease pot on the Vevor like the CS4 has.

It is definitely NOT like a cs4 at all, GX has exclusive design and patent. Vevor cannot legally copy it, here or in China.

Maybe not exactly like a CS4, but the feature list sounds pretty close. Probably designed just different enough to avoid any rights or patents, but it's the same basic idea.

Both have combined air and water cooling, a 350W motor, auto-shutoff, a 1 year warranty, and are very close to the same size and style.
Vevor has a built-in internal inverter, while the CS4's is external.
Vevor states 3 hour continuous run rating, while CS4 says 5 hours.
Vevor 4500psi, CS4 5800psi.
Vevor has a temp gauge, CS4 has none.
Vevor weight is 23 lbs, CS4 is 29.

No internal filter
No grease pot
Cs4-i has an internal inverter
No over temp safety shut off (at least not mentioned) vs having to watch a temp gauge.
I would imagine there are other significant differences as well.

Maybe someone will buy one and pop the cover off...

Yeah, I was hoping someone already had...

Not me…stick to what has been proven. I know a supply of complete cylinder assembly replacements for the cs4 will be available in the U.S. Should keep the cs4 running for many years.

bought one today for my youngest grandson and his FX wildcat MKIII compact BT he will be getting for his birthday
very soon, got it for $253 total shipped. he should be able to pump that 300cc bottle a lot of times before, if any problems
happen within the 1 year warranty.
i will check out the compressor and see if its anything close to my CS4.

It would be great if you could post a few pics of the insides...

 

[gendoc]

Yes, please let us know. That would be great. Thanks!

well i will tell yall this.........GX packing is nothing like the vevor packing !!!
its very well protected with corner bracing and impact cushions.
i aint got time to try it out this evening.......hopefully birthing a calf this evening and got the vet on retainer.
all is good here on the home front !!!!

 

[gendoc]

ok, i've got 3 internal pictures of the possible vevor/cs4 clone, but as usual my cell reception for uploads sux at this time.
if i get my reception back, will post pics here.

finally..........

Looks like they added water cooling to standard 3 stage cylinder of square box compressors. Looks like 1/2 the volume of coolant of the cs4. Should work pretty well. The square box 3 stage were pretty good, so long as you didnt overheat or start under pressure.

I'll state up front that I don't have any of the compressors involved in this comparison, but I'm curious about you stating it is a three stage compressor . . . I only see air lines that would indicate it to be a two stage compressor, if I am looking at things properly.

Can you explain where the third stage of compression occurs? The two I see I illustrated below, but I don't see a third . . . just curious, as three stages of compression is massively better than just two for robustness, and most of the cheap compressors are only two stages . . .

There is a large piston that move up and down, small piston inside of it. Up stroke is 1st stage on large piston and 3rd stage inside of it. Air goes to second stage through check valve in large piston. Down stroke is 2nd stage air goes through copper tube to feed 3rd stage at the very top. Weakness of this design is 3rd stage heat (water cooling solve) and connecting rod weakness connecting to gear (don't start under pressure). Cheers

Rotate radiator or you'll never get all the air out of it.
