I just picked up a Harman PF100 for $1000. It's in great shape, just needed a good cleaning. My question is, what's the model number for the Dayton 2000 cfm distribution blower? The current blower is the standard 1000cfm Dayton 4c589b. I've got the part # from the manual, but am looking for the Dayton model#. I'd like to bump up the current blower.
