Would this work well as a booster fan for a long-run HVAC duct? Would the fan speed be too high for such an application? Diverting too much air?

It can be used for such a purpose but with out an air flow meter is hard to figure out what any change would do to any system. You could always over power a system then use an adjustable inline damper to bring the air flow down to what is needed.

The flow through this unit would probably be too large to be used this way. A better choice might be the "Panasonic FV-10NLF1 WhisperLine 120 CFM In-Line Fan, 4-Inch Duct" unit Amazon sells. I use the 120 cfm unit as an exhaust fan on a switch for a single bathroom. I use the 240 cfm unit as a vent fan on a timer for four rooms. You will probably need to connect the power to this unit through the furnace controls so that it is switched on and off with the furnace.

no I don't think I think it is too powerful to use for this type of application

Not significantly. If you are looking for a quiet solution and are somewhat electrically savvy, try wiring two fans in series and ditch the speed controller. I found this configuration was much quieter (practically silent!) than using the fans on the low setting of the speed controller, and still moved a surprising amount of air. The speed controller is not a very "elegant" design, and causes the fans to emit a buzzing or humming noise at low speed.

This a very powerful strong blowing fan! Just remember ur not adding cold blowing air, it will be just circurlating the hot air. Hope this well helpful :)

It's a horrible idea to use this fan to get air into a room to be honest. This is simply a computer fan, and the dust and dirt it will pull it from outside will ruin itself. Its also just 120mm, perfect in a computer situation but not for a house... Yes, in theory your configuration would work though.

Don't mount the fan too close to the furnace to avoid temperatures over 140 degrees.

As a replacement unit for a vent fan, yes (assuming 2X6 joists above with vent duct and power line in place). It would be a real trial of luck and ingenuity to install afresh, running in both power and duct.

I wouldn't recommend that application. This fan is made to move air from a case or cabinet not to exhaust a bathroom. It's not big enough

There is a pull chain that controls the on/off and fan speed. We have our fan mounted in the garage from the ceiling. It is provides a very good airflow and would likely be too strong indoors if run on high speed. I do love the fan. I wish I would have bought it years ago.

That's a tough call with the supplied information. If the room is going to be used for a single purpose...how much light and would you be supplying the air from outside to the room than outside? Ultimately get as much fan as you can afford (think long term) and a GOOD speed controller. You can always turn it down but you can only go so fast. My fan came as a 440cfm. Don't forget ducting and band straps. I hope this helps

I am not a HVAC guy but I would think that it could be a valuable tool to measure duct air velocities on a relative basis. It is a sensitive instrument but only measures air speed. I suppose you would have to do the calculations in order to calculate cfm. One of the things I use it for is to measure air intake speeds into duct work I set up temporarily at jobs to create negative pressure within houses as a means to minimize dust dispersal. I love this meter. I always have it handy in my toolbox.

Since I don't know what you want to use it for, I can't really answer the question properly. I will tell you that I was having an issue with my satellite receiver not getting enough air movement in the cabinet I have it in. One of the techs told it was probably a bit too warm in there. I set this up in the cabinet and it seems to have resolved the issue. I liked the variable speed to it because I could run it faster in the summer and move more air, and dial it down in the winter a bit. Only downside is that it's a bit noisy at the higher speed, but I'm not aware of a more efficient way to move air in a small area. Hope that helps. Ray

I set mine up to draw fumes or hot air out of my garage. It fit perfectly into the opening of a roof vent. It is only max 400cfm so your volumetric flow is not high, but to move some fumes it works. I found paint spray vapor deposited on my fan blades so it does work somewhat ok. But it is not sealed, spark proof or waterproof so think about your application carefully & be sure you are not creating a hazard

I am using it for my 20 X16 shop which has a sloped ceiling that is 15' at the peak and the unit seems to be doing fine. I usually run it on low. I have had it less than one year but seems to be working fine and capturing extra airport dust acceptably. It also acts as a heat circulator by moving the hat air down from the ceiling. Good Luck - Andrew

This is not a ducted central high static air handler. This is a Ductless Mini Split Fan Coil Unit. It does not have the external static pressure to blow the air all the way across a very long hallway. Your installer is wrong. Place it centrally. Or install one of the Pioneer Ducted Inverter type systems, so you can bring air to 4 separate locations via ductwork all along the hallway.

This is a high flow volume fan. I am using it in a warehouse setting. It is not an air conditioner and not recomended for a small spaces.

I have an 8" fan and it works fine. I'd have to check the maximum air movement, but I'm almost sure it exceeds 265 cfm.

no way. Im using it on a single 1000 watt hps with cool tube and it does the job as long as my ambient temps stay around 60-65 F. Ambient temps are really the big factor. This is a great fan though.
