Part of the refurbishing process on a Harman P61-2 I've acquired involves the replacement of the distribution blower. One can find Dayton 2C647 blowers that fit for a low as $58 but they come with permanent split capacitor motors while the Harman blowers at over triple that price are shaded pole motored units. As I understand things, shaded pole motors are more effectively controlled by the speed controller of the Harman control board and may end up being quieter as a result when run at less than full power.

Do any of you have experience running the less expensive PSC blowers on your Harmans?

Thanks for any informed replies.

Don,

Thanks for the links. I like the concept of just replacing what's needed but in my case the whole blower assembly is missing as the previous owner adapted a round cross section blower to finish up the winter and discarded the old defective Dayton blower leaving me without a carcass. I also wonder if the replacement linked is actually a shaded pole motor as it doesn't seem to specify. If it is and I could get a hold of a used carcass I'd certainly consider going that route.

Anyone out there with a dead blower they would part with?

Still looking for more insights.

I got a Dayton shaded pole blower for mine as a back-up before they changed to a permanent split capacitor. But I saw these on ebay 2c647d that says they are shaded pole. You would have to contact the seller to verify.https://www.ebay.com/itm/Dayton-2C6...lower-1350-1550RPM-115V-134-CFM-/282451148179


Thanks for the link Funnydirt14,

The seller lists that blower as a Dayton 2C647D Shaded Pole 1/70HP PSC Blower 1350/1550RPM 115V 134 CFM. The PSC stands for permanent split capacitor. I went ahead and purchased one of the $58 units which is also listed as a shaded pole PSC motor. It seems to function perfectly in test mode it either high or low flow. Only time will tell if it modulates properly along the whole spectrum or speeds.

The paint just arrived today so that's my next project.
