The oil-less compressors use a rubber diaphragm (think round) that moves up and down to create air pressure. They run at extremely high speed and make lots of noise. If the diaphragm tears or gets a hole in it, no pressure.
The oil type pumps have pistons and a crankshaft just like an engine that create pressure - think the compression stroke on an engine, only every stroke is compression with the valves that are in the head of the compressor pump.
Think like this - how long does a car engine last at 5000 rpm? How long would that same engine last at 2500 rpm?
Like I said before, keep clean oil and a clean air filter on a belt-driven piston pump and it will run nearly forever. (Don't buy a direct-drive piston pump, they run too fast to be reliable)
