Rated 5 out of 5 by 2reviewers.
Rated 5 out of 5 by Used this in combination with a snap thermostat for a passive/active solar thermal wall air handler. Been working like a champ for several years now. Would be nice to have full maintainance instructions linked since I lost mine. I assume a few drops of oil for the surface bearings annually would be all.I do note with a bit of trepidation though that the product is now made in China. How is the overall product efficiency now that windings are usually made with second grade copper? Come on Grainger..lets by this stuff from our workers here...Demand that and you might still have a customer November 9, 2013
