Rated 3.0 out of 5.0 by Ted Warning may not be useable for you
WARNING note the specs - 210CFM!!
There are higher flow inline duct booster fans on the market. You may need one of them.
This fan is lower CFM. The advantage of lower CFM booster fans is that they don't make a lot of noise. So if you have a short run duct then you can use this fan directly into the heating duct and it will be fine.
But if you have a long run duct then you will need higher CFM booster. However you will need to insert a higher flow booster into the duct with flex tube couplers, The flex couplers dampen noise and vibration. Just use short lengths of flex tube ducting to make up the couplers.

Air flow from unit was much lower than expected and blower fan is made of plastic.

Rated 5.0 out of 5.0 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 5.0 out of 5.0 by CAMJ Duct Fan is Excellent
I've read a number of posts on the web about duct fans saying they don't work but that isn't true. Fact is they do work! I installed this fan in the duct going to the office over our garage which was practically unusable during winter and now it is one of the warmer rooms in the house. I also changed about 11 feet of the 24 foot flex duct run to metal duct. At the register the air flow has doubled. The fan is about 20 feet from the register. The office is now at 70 degrees an increase of 5 degrees. Our thermostat is in the living room set at 68. The fan has made a huge difference!

Rated 1.0 out of 5.0 by SuperDuper Not Worth It
This Booster Fan (or lack there of) is not worth it. It does not have enough blowing power to over come the static pressure in an air duct, you can look at the specs and it will show you that it does not have the power to do anything besides just sitting on your desk and blowing a nice stream or air on your face but once it is installed in your air duct, it does not do anything. If you are looking for a real In-Line Booster Fan, look for a Centrifugal fan, it will save you the time and effort of not having to redo the work.

Rated 4.0 out of 5.0 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.
