There are larger vacs made for handling grain. One brand is

Sounds spendy to me. I have a total of $35 in both of these, if you

(not clog the filter) and it will remove some restriction. You really
don't need the shop vac's can, either. Something like a dust
collector may get higher air volume. Something like:
