Plenty of power new my garage has its own service if I need a 220 I can put it in only using about 1/2 the panel was looking at a jet vortex cone dust collector 2 HP
FYI, I have the Jet Cannister, 1 1/2HP motor and was interested in the vortex.
I started to build my own since Jet will not sell the cone to existing owners.
I ended up making a Thien baffle. I think this works better than the cone. It is also very easy to make and retrofit. For me three holes and screws.
I have good airflow and suction with my 1 1/2HP unit which is presently set to 110V but can be rewired to 220V. I do not have an airflow meter but I can tell the suction improved with the Thien baffle.
The 2HP is likely 220V.
