[Shop-talk] Looking to buy a compressor

[Darrell Walker]

OK, I will submit to the wisdom of the list and mount the radiator between the pump and tank  :)

I will wait until I know the compressor is running fine, though it will be a mostly bolt-on installation and can be undone.

Since I already have the transmission cooler, I’m going to use that, and mount it on the fan guard cage, so that some of the air from the fan will be pulled through the radiator. I know this will increase the temperature of the air that then goes to cool the pump, so I’ll keep an eye on that.

The question I have is what to use for plumbing.  Since there could be some movement between the compressor cage and the rest of the compressor, should I use a hose instead of copper tubing (I’m thinking it might work-harden then break due to the vibration).

If I do need hose, I’m looking at some PTFE, stainless braid covered fuel line.  It is rated for 2500 PSI working pressure, 8000 PSI burst pressure, and 450F temp, so it would seem up to the job.

I will also mount a water trap with an automatic drain between the radiator and the tank, and since that will all be upstream of the unloader valve, it will drain each time the compressor cycles off.  I’ve found two kinds of traps, one that is basically a container that would go on the end of a drip leg, and one that all the air passes through.  Any thoughts if one would be more effective than the other?  It would seem like passing all the air through would be better, as some water could make the bend with a drip leg.

Thanks,
Darrell
