One of the most important things to remember when dealing with pneumatic's is the volume of air required. The students on our team have had a hard time grasping this as well.

When looking at the specs this would make one of those "Crappiest Pancake compressors" below the specs needed to operate.

Boyles Law is a great thing to know when working with pneumatics

I don't think the CFM requirements are really as high as the instructions entail. I have the absolute crappiest compressor you can buy, rated at .7 CFM at 90 PSI (I think it was even worse in reality) and it was easily able to keep up with normal riveting work. Our robot's air system was also easily able to keep up with 4 air tanks attached.
