Wow, I'm impressed. I didn't expect to find an electric compressor capable of powering air tools without a tank. Looking at it, I think it's actually a York (engine driven compressor) hooked up to a relatively large (200amp) electric motor. Great idea really, comparable performance of an engine driven compressor with the ease of installation of an electric.

Another source of good compressors can be found in old junked travel trailers from the 60's and 70's. Back then, the water systems were pressurized with air compressors which pushed the water thru the pipes. Trailers have since abandoned that practice and now use electric water pumps to move the water. I got an excellent 12V pump free for just removing it. I discovered it needed a new piston but the cost was minimal and I have an excellent air compressor. Much better than the cheap ones found in stores today.

I have a Masterflow and it works great. I was able to inflate a 32 inch tire in about 5 minutes.. An F.Y.I. though, it's a proprietary connector, and the threads are non standard. I wanted to add a longer hose, and an additional PSI gauge. I had to remove the old hose and re-thread the maifold. I also made some changes to the manifold heat sink so it disipates heat better. After that was done, I am now able to plumb into a manifold or fill a small air tank.

You had to re-thread the manifold? Mine had a proprietary connector on it, but a wrench and a quick run to a hardware store took care of that. IIRC I just had to buy a 1/4" to 1/8" reducer and I was good to go Maybe they've changed something recently, or we had different models?

This pic was taken while modifying my stock AC unit into a belt driven air compressor. On the far left, you can see my red masterflow, modified with a standard quick connect air fitting.
