This is a John Bean, which is the manufacturer that Snap-On distributes. It's a fairly nice machine from what I can tell... but I'm no expert on tire machines, just glad I don't hafta fight levers any more.
my air system is comprised of three compressor units in three different buildings, all plumbed together, and into the house basement, attic, henhouse, I've got connections at the lightpole in my driveway, down by the sawmill, in the grainery, in each grain bin... basically everywhere.
Each compressor has a dryer... the unit in my attached garage is a 4-cylinder 2-stage 15hp Brunner feeding into an Atlas Copco refrigerated dryer, then a reciever-dryer, into the Brunner's 400-gallon horizontal tank. In the south grain bin is an Ingersoll-Rand 3 cylinder 2-stage 7.5hp with a secondary heat exchanger then receiver-dryer, to a 100-gal vertical tank. In the generator shed is a 2-cylinder Quincy driven off a PTO sheave on the Hercules JXLD of my 35kw gen plant, it has an intercooler/aftercooler on electric fan in the rafters...
usually, the only one that runs is the Brunner. If I'm running the blast cabinet... MEBBIE the one down in the grain bin will kick on, but not usually. If I'm running a big impact gun or a body grinder or cutoff tool down in the bin (it's a workshop now) then the Ingersoll may kick on (the buildings' interlinking is 1/2" ID, so it won't flow a particularly high volume between for long periods). The plasma table is really the most hungry consumer, followed by the blast cabinet, air router and cutoff tools.
If I'm on emergency power, the grain bin is shut off, and the garage Brunner is knocked out by the load-shedding panel, at which time a low pressure detection will kick the Quincy into action to bring system pressure back up IF I'm running off the big gen. If I'm running off any of the smaller systems, the compressors won't start, as it's too much electrical load to do so. It's rare that I'd be needing air when that happens, but if I do, I just switch to the big engine and it takes care of it.
So... I'm not hurting for air superiority here.... ;-)
