How Long Can I Run My Yong Heng?

Yes let it cool longer the temp you see is only the compressor head temp. The motor also needs to cool down. Without an extra fan it will take longer to cool off the WHOLE unit. So far you are doing ok, but take a break, Rest is important.

I fill a big tank from 200 to 300 in about 15 minutes. If you need to run more check for leaks.

Looks/sounds good.

That should definitely be enough extra fan.

After running mine for 15 min. I let it cool off for 20 before running it again. Patience Grasshopper!

i wouldnt rush it .. nice setup, but id check out a husky tool cart on amazon .. good stuff ..

Is that a muffin fan on the YH ? Is your add on fan blowing air in the same direction as the muffin fan ( if it’s a muffin fan). If it’s not blowing the same direction it’s going to burn up. I’m thinking if it were mine I would re-do it so the larger fan was the only fan but doing some electrical magic so the add on fan is always running.
When I had my Omega, it had a switch for the water pump and a switch for the compressor motor. I made a separate electrical box that had a plug, outlet, toggle switch and 60 minute timer on it.
The plug on it went in the 120V outlet, and the compressor plugged into the outlet on my electrical box I built. When I wanted to compress air I put the toggle switch in the run position and then turn on the water pump on the compressor. Once I verified that water was flowing I turned on compressor motor. Once my air compressing was done I turned off compressor motor at the compressor and then on my electrical box I built I flipped the toggle switch to the TIMER position and turned the timer to whatever minutes I desired, up to 60. Usually 20 minutes.
Then when time expired the water pump shut off. That way I didn’t have to hang around for 20 minutes while the water pump ran. Not that if it ran for 24 hours or so would be a problem, but everything has a finite life.

Your setup looks nice. Do you use ice in the cooling water to keep your temperature so low? I ran mine for 15 minutes today to take my 45 minute SCBA tank from a little over 3000 to a little over 4000 psi and I got to about 63 degrees C. I use a radiator on the cooling water with a fan but I do not have an extra blower or fan on the YH. In the winter the room the compressor is in is cooler and the head temperature stays below 60 C. I've been thinking of adding a fan on the YH, if you are doing this without ice I definitely need to add the fan. I have used ice but I don't normally since I can air my tank up with the one run.

I use a smaller extra air filter and I have it mounted higher so any water drains all the way back to the YH where I vent it every 5 minutes. It seems to keep the color changing dessicant beads in my extra filter from seeing much moisture. I only have to change them maybe once a year. I do collect some water in the YH filter, however. I change it after every run. Today it had a noticable amount of water in it when I squeezed it. Still pretty humid here in SC. I bought one of the big gold filters but haven't installed it yet because the little filter seems to work fine.

Thanks Mike. I use ice packs when I use ice and it clearly helps but sometimes I am too lazy. I keep my cooling system sealed most lf the time. I use distilled water with water wetter in it. You clearly have an effective setup.

I use 1 oz of water wetter per gallon and add about 1 cup baking soda for 5 gallons of soft water. 1 year later still no algae or slime of any kind, closed lid with small holes. No ice or bottles. If I top off my tank more than 2 times a week (15 minutes each) I'd be shooting a bunch.
