Elec. Compressor recommendations?

Any recommendations for a small compressor to fill tires and blow out water lines for winterization? There are several cheapies at Wallmart, but I imagine I can do better. I recall that the pressure to blow out water should be no more than 60PSI, which would seem to be a problem if I also want to inflate tires. Doesn't have to be 12V, as I will not be taking it with us. Thanks for any help.

I used the local gas station's free air pump. Boy, do I feel cheap. LOL

You can regulate the output air pressure - they don't have to work at maximum pressure. For blowing out water lines you want air volume. Five gallon tank, at least, and a 5 hp motor would be good. But I didn't do that.

I bought a Deltal oil-less compressor - . It will inflate the tires and, being oil-less it will not introduce traces of oil into the water lines. I got it at Lowe's for, I believe, $89 a year or so ago.

HOWEVER, its chief attraction for me is that it will store away under the wardrobe floor in the trailer. That way, I can blow out the lines at a campsite (or top off tires) before returning home in freezing weather. If I was not going to carry it with me I'd want something with a larger tank for blowing out water lines. It does the job, but slowly.

Oil-less compressors are somewhat loud. If you want a quieter oil type you can get the filters made to keep oil out of paint guns and so forth.

I'm pleased with my little 2 gallon 120V Husky ... purchased from Home Depot for $89.00 ... probably the same unit as the Sears.

I just store it in the bed of my F-350 ... small and quiet ... great for inflating my truck and trailer tires before I hit the road.

I am not a real fan of Sears power tools but got a 1 1/2 hp for $100. 2.4 cfm at 90 psi (probably on the low end for blowing out water lines), cast iron cylinder liner. It is small enough so I mounted it in a storage compartment, 125 psi so I can fill tires without taking forever.

I mounted a Sears 120 volt, oil-filled air compressor, with a 2-gal tank, just behind the right, rear wheel well in the truck bed. It fit the recess nicely, with minor modifications and re-piping of the discharge and gauges, without restricting the 4 foot bed width. I carry two Honda 2KW generators with me on 4 foot wide roll-out platform. This provides more than adequate air for maintaining the tires on the dually and the trailer, using two of the +/- 20' coiled lengths of air hose, coupled together. To my surprise, however, the compressor needs to have both generators running and hooked up in parallel! This isn't a problem - since I have the correct parallel cable hookup - but I would have sworn that one generator would have been adequate before I tried it!

I have two small 12 volt heavy duty compressors tied together to a one and a half gallon tank mounted under the van. The compressors charge the tank to 110 psi and operate the air shocks and the pac brake on the van. I have put air fittings on both sides of the van and one inside to make an air hose connection if I need it. You can get quite a good short hi volume blast of air when needed to clean things off and keep your tires inflated.
