I have a 2hp carbatec dusty and i am going to mount the motor and impellor on to a thiens separator and do away with the filter bag and vent the dust outside shed. Just not sure what size to make the separator for the drum 18 " or 22" Dia. , Bill Pentz site said smaller Dia. finer separation but more resistance to motor , larger Dia. less separation less load on motor,this was for cyclones with cone .I want the most cfm I can get out of this system Anythoughts anyone
