Ive got a standard router 4'x4' divided into 2) 4'x2' zones. Trying to decide between a used regenerative blower that will do 50" water at 100 cfm for $300 or a universal motor vacuum head for $130 that will do 148.8" water & 110.3 CFM. I'm thinking that regen will be nice and quiet but the vacuum head spec is so much better- what should I get? Will either pull thru MDF on the full 4x4?
