If you already own a compressor, then you will only need the ABS 3 system. You may still need to get an adaptor to match the air compressor to the Copic 1/8 inch threaded hose fitting. This set-up will work with almost any compressor that can be regulated to run at about 40 psi.
Look at this list to identify the proper air hose you will need for your ABS configuration:
AH4-8 Air Hose 1/4 – 1/8 For use with the Air can 180 only
AHC4-8 Air Hose 1/4 – 1/8 For use with air compressors running a 1/4 output
AHC8-8 Air Hose 1/8″ – 1/8 For use with air compressors running a 1/8 output (Standard Sparmax or Iwata fitting)
