Re: Hooking Air compressors together. Bad idea?
It will work just fine. Does each compressor have it's own tank, or is there just one tank?
Assuming a tank on each compressor, you want a shutoff valve at the tank, then a pipe or hose to a common manifold. Draw all your air off the manifold.
If you have only one tank, run the output of each compressor through a valve to the tank, or to a manifold that's plumbed to the tank. Then draw all your air out of a different place on the tank.
I would also suggest that you have a separate pressure switch for each compressor, set for slightly different pressures, so that they won't all try to start at the same time.
You want to have things valved so that a compressor can be disconnected without disabling the system. Also make sure that each pressure switch is seeing the pressure at the compressor it's controlling. You don't want to rig something that would allow a switch in the tank to start up a compressor that's been valved off from the system.
I like using hoses in air systems to isolate the vibrations of the compressor from the rest of the system. I had a hydraulic house make up a 2-foot piece of 3000PSI hydraulic hose about 10 years ago, and it's working fine.
