Keep in mind, EVERYTHING goes throughs the fan on a Kirby, (it's not a bypass system) and the vac is a sealed unit. I've probably replaced 50 of those fans...First better make sure foam ain't soy based. Mice love dat snack food.
Second look up Thein Seperator. Build 1 and connect to shop vac or better industrial straight blade blower.
You gotta go cheap, hunt up a old Kirby and hook it into de suck line bout half way to de collector. Nice thing bout Kirby, replacement parts are available from Power Flite.
You go messin wid kooon crap you want positive incoming air and good respirator. Not bad idea to have safety man watchin yer back, koons can get very nasty.
