High performance compressors

[craig_colliass]

As the title says, I'm looking for a supply for high performance compressors for a possible HW project,
on the feather I'm using these.

they work very well and are cheap but I would probably need 4 or 5 of them to get the capacity I need!
any ideas?
thanks

What jumps to mind would be PTO driven compressors from a tractor. Usually fairly small units that bolt onto a tractor and run off the PTO shaft. These will run at around 540rpm give or take and can be found easily enough second hand or new on ebay / gumtree. You will of course have to run them off a suitable motor with gearing but I'm sure that would easy enough to rig up.

Some specs taken quickly from a unit on ebay - Twin Cylinder - Working Pressure 8bar (116psi) x 90 lt/min (3.2cfm)

Thanks Gary, I think that might work I will be looking into one of them some time soon
