How hot is too hot for an air compressor pump?

[R-mm]

I have a California Air Tools 2hp 240v oiless compressor (10020C-22060) that has no published duty cycle. I take readings of the heat sink with my IR thermo occasionally. I will call the company on Monday to see what they recommend but wanted to ask you all - what would you consider too hot for the pump heat sink or air outlet?

I know it gets hot, what temps are you getting?

If i go easy, 190f. If i push harder easily over 220f

Here's an older air compressor thread;

You're fine.

My Champions typically run upwards of 300F on the head. Not uncommon for the discharge tube to be around 270F. My Jenny/Emglo's were pretty much the same. Both have 80% duty cycles.

The above thread has some interesting information on the discharge temp. They say 300F is the max.

no neat sig line

If it bothers you, add a fan to force more air over the compressor head; it will run cooler. Even the $20 box fan from Walmart directed at the pump will help, even after the compressor turns off it will continue to cool it.

Thanks, great info.

The standard answer is:
A. put a cooler on it.
B. Change the oil more often

Doesnt really apply here. I have an off topic question. How do you like your compressor? I have been fascinated by how quiet those machines are. I dont really NEED another compressor ( esp a tiny one). But, I see that pump on brands all around the world and I wonder if maybe I should find some room for one.

Would you buy it again?

It was my second from Cali Air Tools, I like them both a lot. The low noise thing is really really true. It is oil-less FYI. Alum heads. I haven't really punished it so I can't say if its suited for heavy use or not. Looks very nicely made though.

I have the 110v version of that compressor, and don't exercise it enough for temperature to be an issue. Did you ever contact California Air Tools? I would think oil-less has less temperature tolerance, although the sleeves are teflon (melts at 620F).

I do like the compressor, although I regret not going for the 15 gallon version as it will hit 150PSI instead our 125PSI. Not that I need that extra pressure... but bigger numbers!

I did call them and got a so-so satisfying answer that the "max" duty cycle is 70% but they "recommend" 50%. I pressed them on why its not in print anywhere and the guy gave me attitude.
