AlanB said:What you might consider is running one of the "standard" gas powered compressors like you can get at HD or Lowes, and then if I was doing what you are trying, I would add a "large" (as large as I can fit) air tank for volume.
I would also use a leaf blower to blow out the big debris, then a blower with a 3' extension nozzle to get the detail cleaning done.
I've thought about those standard gas powered compressors before, but how well do they stand up to being stored outside 24/7 and riding around on the back of a truck? Most of the compressors that you can buy at the box stores are made for being stored and operated inside, out of the weather.
****, I've thought about just buying a big *** power invertor and running a standard 120 VAC compressor with it, but that's a band-aid type way of going about it. So I was thinking that a compressor specifically engineered and built for mounting on a truck and being outside in the weather 24/7 would be the best type of compressor to get.
