And if you take it in the cooler house that could cause condensation.

I do not filter air between the SCBA tank and the gun. I have a desiccant filter on the intake of the compressor. The Daystate compressor does leave a bit of an oil smell in the tank, and I notice it as well when shooting. However, I cannot get any droplets of oil from the tank.
Condensation will occur inside the tank if the air is not dry. This is regardless of going from a warm outside to a cool inside. When the tank eventually cools water will condense. The tank will get warm on filling, but not as much as when it is filled by cascade air cylinders like they do in some SCUBA shops.
I have checked my tank for condensation after filling by leaving the tank valve down until it has cooled on a cold winter day, then cracking the valve into a plastic bag. I have not found any significant moisture after doing this. The built-in in-line dryer along with drying the intake air seems to work for me. However, I do not live in a humid climate.
I am considering adding an in-line filter between the compressor and tank to remove the little bit of oil, especially if I decide to fill other's tanks. This may be something that I'll do when we host a larger airgun match at our range.
