Or maybe any appliance repair shop / handyman can wrap a new heat blower motor for the Haeckflosse SE if you dont want to pay $300 for the genuine item. Regular repair man can even go beyond original specs for a high performance fan, who knows?

Just dont let em remove the metal clips on the fan-blade.... These serve as ballance weights same as lead weights on wheel rims. Or better yet, get the fan blades ballanced again after the rebuild is complete.
