If you can figure out how to pull the air from close to the top of the
vaulted ceiling. The air there will be warmer. It would be really
nice if you could design it so the fan will pull the air from the top
of the valted ceiling and either direct it into the garage or back into
the house. Then you could use it in the winter to prevent the air from
stratifying and to cool the house in the summer. Blowing air into the
garage will get rid of welding smoke. Probably not sawdust.
