I think this is all to code; sure someone will correct me if not:
Run a dedicated circuit with 10-3 wire -- double check me on the gauge, but
that should be good for up to 30A. You can start out with a lower current
single-pole breaker and matching outlet for your current compressor (the
2nd hot wire will be unused.) Later you can upgrade the breaker & outlet
pair to a matching higher current 1 or 2 pole setup.
There's a standard plug & receptacle for each voltage / current combo, and
usually also a "twist & lock" version of each. I used the twist & lock --
it gives me a nice big plug to grab onto with my fingers a comfortable
distance back.
