Question: what is the maximum temp this fan can be exposed to? I plan on using it in a heat take-off duct from a wood burning fireplace. It will be 20' out
Document: Very good fan. I use it to pull air from my basement and pass it around my sealed combustion fireplace to heat the house more efficiently (removed the weak 150 cfm squirrel cage fan that came with the fireplace). I also created a damper &#34;by-pass&#34; so I can easily reverse the air flow and heat my basement using the same duct system without having to flip the fan around (BTW, the fan is not electrically reversible).
This fan is amazing im actually using it in my  Napolean nz3000 wood burning fireplace after there $500 fan defaulted after a year and a half. Even if the fan does eventual wear out i still will save an amazing amount of money. I run it 24/7. No issues so far.
strong powerful fan. I'm using it to bring more furnace heat to a big upstairs bedroom. Worked great with the A/C, can't wait for the heating season.
I had been looking for a duct fan like this to circulate the the air to/from my basement. The one I had been using was wimpy and hardly moved any air. This fan moves a lot of air, and not really any louder than my old fan. And it even came prewired with a plug. I am very pleased.
This fan is alright if you're gonna be using it for moving air around your house, yes, but in a concealed/behind the scenes manner. I say this because first of all, this fan is a bit unsightly compared to other models out there. So if you plan on using this with a hydroponics or growing setup that you'd prefer to be aesthetically pleasing, this wont be this first option.
Awesome duct fan, the bracket for mounting is a little weak and takes a little skill to install, I ended up putting in a cross bar underneath it to help hold it level, definatly clears the room, I mounted it in my newly insulated garage because thats where my wife and I smoke so no more smoke chamber in our now heated garage up here in Wisconsin!
This thing is great it's quieter than a less powerful one I had. Works great for moving heat into the cold area of my house!
I recently installed a new register in my family room open area. This area had an imbalance of 4 degrees from the sleeping areas. The company that installed the new register used flexible duct for the run. With 50 feet of flexible duct (not the best in transferring air) compounded with having to snake that duct around several columns, the result was a disaster. The area increased by 1 whopping degree!So my next solution to the problem was to install a regular 240 CFM inline fan.
This duct booster has all the power I need to draw more conditioned air into an upstairs room (via the return duct).
I run the fan for about 2-3 hours at a time, 1-2 times a week and have been using it for about 2 months now, no issues so far.
Answer: yes
