In this video, I discuss the modifications done to this Yong Heng compressor and conduct the final test.
Yong Heng final test

Thanks for sharing those ideas. You’ve done a nice job. For the record, how much do you suppose you have into your setup? Compressor, cart, radiator, cooling fans, pumps, fittings etc?
I know it’s not all about money, most of us are tinkerers and it keeps us entertained.
I for one, will be very interested to know how many hours you get out of your YH pump with the additional cooling. I hope you keep us updated. I wouldn’t be surprised if you got double or even triple the lifespan. However my limited experience tells me on my compressor that vibration is likely a big factor on mine.

Not trying to be a downer... but how much did that whole rig cost? By my estimate you could've gotten a tuxing 032 with a 4 year guarantee for the same price or less.
In any case I appreciate the work you've done.

Did you test any of the changes separately? I would be interested to see how much the greater water flow through the second stage jacket helped. Or how much each incremental radiator helped. I couldn't hear the first part, my sound was too low, but it looks like you have cooling on the air lines (?). If so, so you know how much that helped?
I have one radiator with two fans on mine but I have several gallons of distilled water with water wetter in it in a sealed drywall bucket below the radiator. I've thought about making a 1 gallon version of my setup, your installation may inspire me. I recently refilled my 45 minute SCBA tank from ~3200 to an indicated 300 bar. But the pressure comes down a little as the tank cools. I started higher than 20 C, I think it was more like 30 C and I finished at just over 60 C. I was not using ice. I have but I am not sure it would make much difference for my setup. I've gotten similar results on tank refills with frozen pop bottles in the coolant. My temperature goes up very quickly to around 50 degrees C but then slows down a lot to where it isn't hardly going up by the time it gets to 60 C. I thus think I could run it a lot longer if I wanted to let it go to 70 C. My tank refills take 15-25 minutes depending on the starting pressure. I am not sure I could refill a good sized bottle in one run, however. Maybe. I have but without the added cooling I did it in several runs. I also have a fan blowing over the motor towards the compressor. I think that helps a little. All my cooling passages are stock but I have a little bit larger pump. My bucket is on the floor with the YH on a counter at about 3 feet off the floor. So the pump has to push the coolant up about 3 feet.
I vent the YH every 5 minutes of run time to minimize changing my color changing dessicant beads. I have the stock + extra filter above the YH so water that condenses in them may flow back to the YH. I like using the stock filter because I see some oil in it (discoloration anyway that I think is oil). I bought a big bag of the elements from Aliexpress and change them out after each bottle fill. I let the cooling continue to run while I'm changing the filter and my temperature will fall at least to the 30s C in the few minutes that takes. I normally turn the cooling off then.

I don't know how much I spent, but I would guess about $700-$800 for everything. At the time I purchased the Yong Heng, the availability of other compressors was much more limited. I don't remember when the Tuxing 032 was released, but I know that when I was looking to buy the compressor initially, it didn't come up in any of my searches.

The only thing I tested separately was an upgraded water pump sill using a 5 gallon bucket (no other mods)
