Found a very quiet-rated ceiling fan!

Anybody know anything about this ceiling fan?

• Panasonic WhisperCeiling FV-15VQ5

It's rated at < .3 sones! That's the lowest noise rating I've ever seen in any kind of exhaust fan.

I'm planning to use it in a small closet, about 2' x 3' x 6'. Blowing exhaust air into my attic without any filter. Should this work without smelling up the house? Quiet operation is my biggest priority.

(Of course I'll be using sound-dampening measures, like insulated ducting, FatMat, etc.)

Kind of expensive for a 150CFM fan, but if you're going for quiet, then this is pretty solid.

The fan that I mentioned in my first post here is working out great! I put it on the top shelf of a cabinet that I'm turning into a small grow room. Used insulated ducting and bolted the fan to the shelf with foam rubber in between, in order to reduce vibration. Even with the cabinet wide open, this fan is really quiet. Once I put the doors on and insulate it some more, nobody will hear it. The water pumps in my hydroponic system will be much louder than the fan.
