I have a '60's vintage "Mercury" fan, Model #M622 (Mercury Fan Co., Cincinatti, OH) that appears to be the same as the 8210. The blades of the butterfly damper (7.75" dia.) are damaged. Would the ones for the 8210 fit?
Thank you for your question on the model M622 vertical discharge fan. The damper for the M622 is no longer available and since the M622 is over 40 years old, we would not be able to tell you if the damper for the 8210 would be an exact fit. You may want to find an in-line damper to place in the duct work.

is there a recommended thermostat for fan
would like the fan to operate when utility room reaches a certain temperature,
Thank you for your question. You can use the Model 70TW. The 70TW has a "comfort zone setting". The fan will activate when the temperature reaches your "set" temperature. For further assistance, contact Technical Support at 888-336-6151.
