So, would a properly design receiver be something a company could produce as an aftermarket add on that would make sense in conjuction with a drum or widebelt usage on a cyclone?

To PHil's example, what % of increase in cfm or fpm could be attributable to the addition of the bell mouth? My understanding was that a bellmouth inlet added significant enough flow that most units were tested with one for purposes of marketing claims. Dave
