Rated 4 out of 5 by This is a good low cost exhaust fan. Note that there is no Motor, Belt or Pully included. I was lucky and all my stuff from my old one fit good. It is not the quolity of some, Example maintanence free bearings (no grease fittings) and no screw belt tentioner. it does have a slight vibration. Good value for the money. July 2, 2014
