Soler & Palau TD-SILENT 6"/150MM Low Profile Inline Mixed Flow Duct Fan
easy to wire
this fan is indeed quiet, infact, i think the air coming out is making more noise than the fan. If this fan is placed behind a wall, or surrounded by stuff, i can imagine that you wouldn't be able to hear it. all that being said, it does make noise, albeit, less than other exaust fans on the market. Although it doesn't come with a plug, it is easy to wire into, with easy to understand instructions. Note: there is no ground connection.
