Rated 5 out of 5Â by MP5SDA3 Booster Fan Nice and Quiet
I bought this booster with an in line thermostat to control the humidity in our green house. This fan is designed for use in heating and cooling ducts but makes a nice adjunct in our green house to draw warm humid air to the outside.
The fan was easy to connect up to the thermostat and is quiet in operation. Mounting was easy using a plexiglass panel to match the green house glass panels and was easily sealed using clear exterior silicone sealer. I added a vent screen to keep smal pests on the outside and that was it. My wife is happy which is what really matters.

Rated 4 out of 5Â by arcturus This product is good value and does the job it is intended for
I purchased the booster to replace one that was in our heating system when we bought the house 10 years ago and likely was older than that. It had become very noisy. I had to modify the new one, because the section of 8-inch duct that the blower is in had its compressed end at the wrong end to fit the right way into the heating duct. The booster would have blown air back toward the furnace. This involved drilling out four rivets, turning the motor bracket the other way, and re-riveting with a pop riveter. Sheet metal screws or self-tapping screws also would have worked. I also had to drill a new hole for the power leads. In retrospect, I probably could have removed the motor from the bracket and installed it facing the other direction, but it then would no longer have been in the center of its section of duct. This would have avoided the rivet work, but a new hole for the power leads would still have been needed. The installation instructions do not cover such a modification, so the manufacturer must be assuming all heating ducts are installed the same way -- obviously not the case in our house. I expected the motor would be totally silent; it is audible, but not annoyingly so like the old one. Perhaps rubber insulating cushions where the motor attaches to the bracket would make it quieter. The power leads are short; the junction box would have to be almost touching the duct in order for them to reach. An extra 4 inches of wire would be helpful.

Rated 4 out of 5Â by Cederchip Good product
The fan was about what I expected it to be. I'm trying to push more air to the second floor bedrooms and the fan comes up a little short on volume.
