Guys lets put it simpler... take a air compressor for your shop with small single pump... it will put out 100psi, but only at a smaller CFM of lets say 8cfm. Now you get a bigger air compressor maybe a twin, and it will put out 100psi but with a greater 10.0cfm. Now it will also run less (ie more efficient and less heat) than the smaller one... The bigger unit will run for 2 min to build up tank pressure, and the smaller unit will take 20minutes...
