I use a Porter Cable pancake compressor as in the photo and it works great. I set it to 50 psi for blowing the lines out. The system is good for at least 100 psi and you can go higher than 35 psi. I have our Watts regulator set to 60 psi. If you use a blowout plug like in the 2nd photo it makes it easier too as opposed to the tire valve type. Just set the regulator to the pressure you want and take your time inside getting the water all out.
I have a 60 gal. 3 cylinder compressor but is waaay overkill for the TT. I am planning to install a 12 VDC Viair compressor in the TT and will use that if it can blow enough air but I doubt it will come anywhere close enough.
As mentioned above, once you've used air, you'll never go back to antifreeze. Many use the ethanol type of antifreeze instead of propylene glycol and end up with a bad odor and taste in the spring after de-winterizing. No worries about that if using air. You'll still need antifreeze for the toilet bowl and P-traps and the PG type is a better choice for that.
Now I am getting depressed thinking about this... Spring is right around the corner tho. :W
