I read all through this and still don't understand what the advantage is to adding a small compressor. A pancake wont add significant capacity.? Cycling a 5 or 10-hp motor at intervals isn't a big deal.? Besides all that, the 2 compressors would turn on and off at different pressures so one would always shut off last (unless they shared the same switch).? I assume the small unit would be set higher but why?? Would there be a check valve on the large compressor reservoir to save the small from charging it?? Or am I wrong to assume 2 reservoirs?? What am I missing?
