I bought a Yong Heng from Walmart because it was supposedly a certified YH. The first one I purchased from Ebay advertised as a YH was a knockoff. This one looks like a real YH but doesn't have the logo on the side. Opinions please.
Based on visual inspection, i.e. stainless steel tubing, nuts, aluminum blocks, etc
that will tell you if it's an authentic YONG HENG, but also, of added importance, the name plate on the side of compressor, showing unit serial# and it's manufacture month and year---all combined---
That's how you tell between the knockoff and the authentic.
For me, I'm satisfied!
BTW, I agree with other on this thread: The white printing on the other side of the compressor means nothing
Below is a picture of my Yong Heng name plate.
I purchased it from Orion Motors (through Amazon, they facilitated the purchase and shipping)
Orion has been terrific with customer service. For example, I notified them I had a small air leak and within 12 to 24 hours, they had a technician walking me through the fix process. I'm Very happy.
That's how one prospers, by running their business with great customer service.
Old yong heng have the logo on the side. The new version does not. Mine yong heng is 2019 and it doesn't have the logo on the side
