Here's one for the experts.
Working on an exhaust fan this week, down draft, ban motor & fan. Grainger the only one around that handles anything for them but without model & serial numbers not much help.
Motor is 1/3 HP running at 1725 RPM
Fan is 11" across & 4 7/8" high with 12 blades.
Any Suggestions on getting this replaced. Not sure how to size.
