Air Compressor

Looking for a new air compressor for my National Tradewinds class A. My current compressor is great for tools and my car tires but it takes too long to air up the MH tires to 100psi. Looking for suggestions for one that I can carry in one of the MH compartments
  • Lots of previous topics on this subject. Search for `air compressor'.
  • There are some good 12V compressors, but they are expensive. They are usually so!d for off-roaders who need to air up their tires before going back on the road.
  • Mine is the Porter Cable and I like it. I don't see why Craftsman won't be just as good. Be sure it is oil-free.

    The thing that speeds up the process is the PSI it runs at. A 150 PSI rated compressor actually generates about 125 PSI. When you have 98 PSI in your tire and the compressor only generates 125 PSI, the air flows slowly because it is only 27 PSI difference. That is why the tire airs up faster, at first, when it is flat. It has a 125 PSI difference. The pressure differential is greater so the air flows faster. If you truly want FAST, get a (more expensive) compressor with higher PSI ratings. I know there are 200 PSI compressors, and there may be others.

    I have a 150 PSI Crafstman Pancake. Still takes a bit of time if the tire is very low but if I'm only adding say 5 PSI, does well.. Those bit tires take a LOT of air.
  • I have the 150 psi Craftsman and am happy with it. Not as compact as the pancake and it is an oiler (not good to blow out water lines) but I like it.

    I'm looking at 150 psi by craftsman, will that work fast?
  • If you want fast, you will need to go with a 120v pancake style compressor or equivalent.
