Others Vevor Dual Cylinder Compressor

[SpindleB]

Bought a Vevor Dual Cylinder Compressor as a backup. Air cooled, no lubrication required. Caught it on sale with coupon on AliExpress $160 out the door. US delivery so no Tariffs.

So i used it a few times to top off my 6.8l and 9.0l tanks. Filled a couple rifles too. Seemed okay, noisy fan and slow. But those type are all slow.

About 3 weeks in, topping off a 6.8l tank and heard a THUD and the compressor stopped. Compressor is dead. Contact the seller. Eventually they want to send me parts to fix the compressor. So I open up the case and find that sending parts isnt going to fix this compressor. The whole low side housing is shattered and the piston is just hanging in the air.

Trying to clone the GX models?

Dunno, never had a GX, I have a Tuxing TXEDM042 and had a Yong Heng. Yong Heng went to Oregon with my nephew so I needed a backup. It was on sale and it was coupon time on AliExpress so it was cheap.

Wasn't expecting much but that far exceeded even my dismal expectations. It blew the case apart. That is some fine engineering and quality materials.

I'm an EE not a Mechanical Engineer but 45 years experience in manufacturing (as of 11/11). The case is just a porous pot metal. By the looks of things the piston bound up and the motor has enough power that it just broke the case. But to bind up the piston requires a lot of slop somewhere in the piston, rod or side wall.

Other possibility the piston seized due to heat expansion. But it is supposedly good to 80C and it was only in the 40s when it blew.

These things are constant maintenance. When I did the first cleaning at 15 hours of use(recommended at 20 hours) not only was the tubing as dirty at some of the new barrels we get, almost every single screw inside was loose. Next time I do the teardown and cleaning as the instructions advise, I'll get some pictures. The old saying definitely fits these.

It was just going to be my backup. But figured I would test it out for a while. I doubt it had 10 hours use on it before destroying itself.

My Toauto is sitting on the garage floor with the box containing the new cylinder sitting on top. I figure if the GX dies and I need a backup, I’ll go to the hassle of swapping it out then.

After several days of *negotiation* with the seller I have received a refund. They wanted to replace the self destructed unit. My confidence in the product was minimal, at best, and felt a refund was appropriate. They finally agreed because the alternative was me using AliExpress to handle the refund and they would have to pay shipping and receive the unit.

Probably a wise decision.
