DC using a shop vac.

You’ll likely find that you won’t be able to run a 40’ system like that off of a shop vac as it’s not meant for that. A shop vac uses high static pressure, but little air flow, while a dust collector uses a lot of CFM. Wood did a good article on how to calculate the CFM required in a shop.

IIRC, even the most powerful shop vacs produce something like 200 CFM at the top end, but you should check into it.
