You can use pretty much any air compressor but I'd use a pancake compressor with a 6 gal tank at the minimum. You are just pressurizing the lines of the camper so it doesn't take much volume to fill them. A compressor like a 12V car compressor will probably run too long enough to risk burning up the motor if you tried to use one of those.

You need a compressor that you can regulate down to 35 psi.

A compressor will get rid of most of your water, but to do it right I would also use RV antifreeze. Don't forget to open your low drains and empty your water tank. If it gets really cold where you are use the antifreeze.

Another good point. In 5 years of using my air compressor here in North Texas, where it can get down into the teens, I have never had a broken pipe or anything else damaged from freezing. So far so good. I do take my time and don't rush through blow out process. Also, I leave the low point drains open until our first camping trip in the Spring.

Before I got a pancake compressor I had used a 7 gallon air tank used to top off tires.

Why? PEX tubing and valves are rated for 160PSI of water @73F, I use 90 PSI of air which is much gentler and it works just fine.

Hi,

There are thousands of RV's that don't have PEX tubing. 35 psi is adequate to the needs.

Also not mentioned is to shut off the HW heater switches and empty your HW heater tank. If so equipped, close the inlet and outlet valves and open the bypass line valve. I just winterized my MH, TT, and assisted two friends doing theirs.

Most of us that blow out the lines don't use any antifreeze unless it's to dump some in the P traps.
