I did have the electrician put in a dedicated 20 amp service for the
RAS, a dedicated 20 am circuit for the dust collector and alternating
plugs on different 20 amp circuits. just didn't know if the 220 would
be better. thanks for the info

Assuming you can figure out how to change the RAS to 120v, your dedicated
circuit will be fine.
If you can't, then changing the circuit to 240v is trivial; the hard part is
running the cable and that is already done.
Good Luck
