I selected this fan because I had a narrow opening in my ceiling joints. This fan just fit. To make the width and length small, the fan is mounted vertically in the housing making it taller. This design makes the fan noisier than a similar fan mounted horizontally in the housing. For comparison, this fan is noisier on low speed than Pansonic’s FV-08VQ3 operating at its single speed which is twice the air flow.
This is a two-speed unit and a two speed switch is supplied. I, though, installed it with an existing switch for the fan it was replacing and hard wired it to only run at low speed. The noise of the unit at low speed is very quiet in the room it is taking air from, but it is not “silent” as some other fans are described. There was almost zero noise in the attic above the room where it was mounted. This fan does not transmit noise all over the house. I did not run it at high speed so I cannot comment on that noise level or performance.
I use this fan to clear a 15 ft2 water closet/toilet room using only the low speed and it is more than adequate for the job.
The unit is supplied with all needed mounting hardware except wire nuts. Installation instructions are clear and well illustrated. Installation took <2 hrs for the fan and another 45 minutes for ~10 feet of 4” dia. insulated ducting.
This is a well made quality product. You will not be disappointed.
Bottom Line: Yes, I would recommend this to a friend
