  • Very cool product. Cranks out the air! Love the adjustable speed. Hard to find pipe that fit.
Size: 3 Inch
I bought both this 3"and the 4" version to test out for my camper van. One I will use for my composting toilet. The other I will use for air movement in the main living space until the AC cools down the van. The 3" is a little louder than the 4" but the 3" cranks out way more air than the 4". You can always dial back the 3" to a very quiet hum and even with the lowest speed setting, you get plenty of air flow for the composting toilet. Since the toilet is also in the sealed shower room with a large ceiling, I will need more air vents from outside the room so that when the ceiling fan is on, I can crank up the 3" to avoid back flow air through the composting toilet. The 4" fan is nice but I almost want to use the 3" fan for airflow in the main living space since it makes a better breeze. Even though it is a little louder. The noise is not really bad. Slightly more than the AC noise. only due to the higher frequency which you can turn down as needed. the 3" needs 2.75" pipe adapter to MSTR with a 2” pipe. ~$10 each. https://www.amazon.com/gp/aw/d/B0BQW8W49Q/ref=ox_sc_act_image_1?smid=A34RJ9S07AUY15&psc=1 ... show more

  • Replacements
Size: 6 Inch
These work a lot better than the grey metal ones. Quiet pushes a lot more air and controllable. Supposed to use less energy We’ll see on that. But I love Furnace set up on far side of ranch house so need help to get heat across to other side House feels equal in heat

  • seems quiet enough and powerful flow
Size: 6 Inch
Pros: Fairly quiet at half speed from the outside of the vent pipe. Pushes a lot of air. Motor runs smoothly throughout the speed range. fairly small footprint. No idea of longevity. I'm running half speed continuously for two days now. Cons: You can hear some noise when it is running much like a bathroom or vent hood. At high speed it would make a lot of noise like a vent hood on high. It is about 1/8" less than 6 inches in diameter. Metal A/C tape is required. ... show more

  • Bought 8, 2 have had the bearing(s) go bad.
Size: 4 Inch
I have purchased about 8 of these fans over the last 18 months or so, I use them for a variety of applications around the house, especially for circulating air relating to our woodstove, which is our primary heat source. Overall, they are awesome. They are easy to use, reasonably quiet, and very light weight considering how much air they can move. My issue is, of the 8 I've bought 2 of them (25%, 1/4) have had the bearing(s) go bad within a few weeks of use. For both, I noticed they had a slightly different tone/pitch when running when first installed. Over time, this pitch became noticeable and eventually obvious and irritating. Operation of the fans never failed as I removed them fairly soon after the pitch became obvious and irritating. Given the application I use them for, I both didn't want to have to listen to them and couldn't risk a potential fire should the motor lock up while I'm out of the house. The other 6 fans have been phenomenal, and I plan to give them another shot and buy a few more. I do hope quality control deals with the bearing issue. If not, am going to need to find a different manufacturer (which would be a shame, because these really do have a lot that is desirable about them). I only left a one start rating so it would get more attention. In reality I would have left a 3 star review, but nobody, including myself, usually reads those ratings. ... show more
