We have small compressors and large compressors.  The small compressors come either gas-powered or 110volt or 200volt.  The large diesel compressors come in various sizes - from 90CFM to 185CFM to 375CFM.  We have all sorts of jack hammers and air nailers and even different kinds of air wands that farmers use to blow off their equipment.  We have different sizes of adaptors that can be used when blowing out large underground water systems for the winter.
