If you are going to run the compressor for long duty cycles, especially out in the heat, maybe you should put a length of copper tubing, preferably with cooling fins, out of the compressor for a couple of feet.

Because of PV=nRT the gas is coming out very hot and directly hitting the tubing.

I would bet in commercial applications the air is already cooled before it is distributed around a plant and delivered to systems using the flex tubing. In commercial plants that has to deliver a lot of air they may even push the air through a heat exchanger to cool the gas before storage and delivery.

If you have a shop air compressor you can, but SHOULD NOT touch, the copper tube from the compressor head to the storage tank. After it runs is is very hot, and if you touch it may burn your hand.

The air in the tank now has a new set of dynamics and moisture will condense, rain, into the bottom of the tank. That is why there is a valve on the bottom of the tank, so you can drain the condensate, but I digress.
