sure it can be used, I use water wetter myself. I don't notice a big difference in temps between water and that added but it does have some anti-corrosive properties
and that was my bigger concern.

[tracker1955]

I have my coolant in about a seven-gallon tote, just water with water wetter added, and the tote is near airtight, I think the addition of the water wetter along with being nearly airtight helps to prevent algae growth in the container as it sits long periods without use until I need to top off my scba tank again.

Another vote for water wetter..I actually found it drops the temp and keeps it there longer using it.. I think I got the Royal purple variety..

It's always been my understanding that water is better at cooling than antifreeze.  But for obvious reasons...  Like lower freezing point and some added lubricity...  Antifreeze is often used in applications that demand it.

I've moved to using running cool tap water to run mine on long runs.  I managed to bend my crank, so my rod actually moves forward and backwards on the journal.  Creating a little additional heat on the main shaft. (don't ask) I ran it too long and started to melt the fan off the back, lol.  Otherwise runs fine.  My oil actually looks way better than it ever has.  But does need additional cooling or reduced run time when running large dive tanks.  For bottle fill up to 580cc it is fine using the 5 gal sealed water reservoir I have for it.

I actually looked at a server radiator as a possible way to cool the unit but realized they are just too small.. But a honda civic radiator isn't. lol

I think that may depend on whether you are just filling guns or tanks.

Bought Chemlube 751 off ebay,19.50 a quart and 18.39 for shipping.
Dang pricey but it's good for 3 oil changes,will be enough for about a year and a half.I'm ok with it,got just over 6 hours on the Heng so far.

[KnifeMaker]

I fill an 88 cf bottle darned near ever day. Sometimes two. A quart of oil doesn't last long. LOL!


I wonder if they know that charging more for shipping than it cost thru usps is a federal crime.

They are pushing the envelop to see what they can get away with is my guess.

personally I went with the amsoil compressor oil. Way cheaper and I'd put it against any other top tier lubricant.
I bought other lubes from them so I picked up free shipping and have an account with them so that helps in keep price down.

I got me a youg heng want to convert it over to Fahrenheit the probe is .15 inches the original one the new one is
.19 inches anyone know if I can enlarge the original hole without damage

[LamontGrady]

People have enlarged the hole, I don't think it's a big deal.

There is a drop-in replacement that fits exactly supposedly.

There is also a way to make the existing ones read Fahrenheit. I'm tempted to try it.

"If you have a little experience tinkering, ALL of the Centigrade thermometers that ship with our compressors can be switched from C to F. I've taken apart my thermometer to get to the circuit board, and while I was in there I found there's a pin labeled "F" for Fahrenheit, and if you short that pin to the ground pin, the board will display temps in F instead of C.

I tried it and ir works great!

Lamont - bless be the tinker for those will be the ones forever remembered.

Use plenty of Ice also Keep the oil clean a  must!

[KnifeMaker]

I just made a c to f chart, laminated it and put it on the shop wall. LOL

[tracker1955]

I didn't want to fiddle with ice so I just used a large enough water container that I didn't have to worry about it. I'm never filling more than one scba tank at a time so my water doesn't even get warm.

[Mosin Marine]

I have one of these air compressors and as a disabled person i put hand pumping in the past! Been working great for months
