Our inline exhaust fan is equipped with a high-quality EC motor that ensures strong power at a low noise of 28 dB, which will not disturb your work and life. At the same time, the motor saves 30% on energy consumption, extending its service life.

Pressing the UP and DOWN buttons simultaneously will turn the AUTO MODE off. The auto alarm function is also included. The controller automatically starts or stops according to the temperature and humidity. Note: The controller does not adjust the speed automatically. The speed can only be adjusted artificially.

    • Built a poor man's Bedjet/8Sleep bed cooling setup with this
Size: 4 Inch
I've always struggled with adequate sleep, often waking up sweating. My Oura ring says I wake up 5-10 times a night. I read about Elon/Zuck touting the 8Sleep solution but no way I can afford $3K to cool down my bed. Then saw the Bedjet and it was still too much to try on a whim. So armed with this duct fan and a length of duct hose, I rigged up a cheap setup to test it out. First, I'm so glad I purchased this model specifically. 1) Speed 1 (lowest speed) is quiet enough to sleep with (almost indiscernible with my ears) and yet provides enough air flow even through 16' of corrugated hose to cool a king sized bed. Many other duct fans I considered only have two speeds which I suspect are both too loud and too much airflow. I will say that 2 is a bit louder and likely tolerable while sleeping, but any of the higher speeds and things get noisy. If you're a fan of white noise, it might work. 2) The temperature and humidity sensor and triggers let me be creative to try and trigger the fan only when temps rise above a set comfort level. Leaving the fan on all night seems to be a bit too cool to fall asleep to. I've only tried it two nights now, but my Oura ring is telling me I'm not waking up in the middle of the night and I'm waking much more rested than I can remember. I initially tried the duct down by my feet but it chills your feet too much so slept with it about 1/3 up the bed mostly chilling the torso. The way your sheets/blanket are situated will really control where air flows. Keep the sheets taught with an exit by your neck and you've got wind flowing along your body (too cold). Create a bubble and it just keeps the area cool without a lot of actual wind exiting the sheets. In the future I want to try and couple of modifications including capping the end of the hose and punching holes along the length and having it lay across the entire length of the bed, and more experiments using the temp/humidity sensor to create something that responds dynamically versus on all night. Highly recommended as a sub-$80 bed jet alternative or to even see if you like it. ... show more

    • Works Great
Size: 6 Inch
Quiet for me, but I am using it in my garage on my laser. I wish it had a simple on and off switch, but once set, it turns on every time I apply power to it.

    • Motor is quiet but fan is fairly loud
Size: 8 Inch
This review is for the VEVOR Inline Duct Fan, 8-Inch 807 CFM with Temperature Humidity Controller Purchased in July 2023. This fan works as advertised. It is fairly quiet on the lowest setting (#1) and fairly loud at the highest setting (#10). It was easy to install and basically works right out of the box. The sensor provided seems to be fairly accurate. I installed this to move air from a room that is hard to cool due to poor airflow. I installed this between this room and the kitchen with a stairway to the basement in between. The important part is that it is a total of about 5 feet between the rooms and the fan hangs in the middle with an 8" air duct going into each room. I explain this because the noise levels were surprising to me . Standing in the stairway with the motor, it is EXTREMELY quiet at almost all speed settings. Almost can't hear it at speeds 4 and below. HOWEVER, anything above speed 1 is vey noticeable at the intake and outflow sides. Speed 2 can be heard easily from 10' away and anything above speed 4 is just loud. All that said, continuous running at speed level 1 drops the temperature in my office by about 5 degrees (the difference between 80 and 75 is a LOT to me). If temps build up too high, I can increase the fan speed for a few minutes and then back it down. Overall, it is working well for my application, but I wish the fan was designed for lower noise. ... show more

    • Freakin amazing for the price!
Size: 8 Inch
I have only been using this fan (8 inch w/ controller) for a few days so this is an initial impression. For those interested, read on later for tests that I conducted. The fan comes with a controller and a temperature and relative humidity sensor. The fan alone WILL run without any of these hooked up, but it will be at full speed. The amazing part is the controller that will allow the fan to be run at ten different speed settings. It appears to draw a lot less current than the fan I replaced, although that was 10 years old or so, and it runs quieter even though it moves the air 12% faster than the old one. It also can be run with only the controller attached but not the T/RH sensor, so unless you need to have it turned on/off at specific T or RH settings, it does not need to be hooked up. I can't imagine buying the model without the controller, which is nearly the same price. Following is the technical information. Speed setting 10 - full: 67 watts, 2800 ft/min (all readings are at no load/resistance right at the fan outlet. Ducting friction will reduce the air flow. For my situation with 3-90 degree elbows and 50 feet of flexible spiral ducting, the outlet is 1600 f/m at the 10 setting); 9: 57 w, 2500 f/m (89% of full speed); 8: 47 w, 2300 f/m, 82%; 7: 41 w, 2200 f/m, 79%; 6: 35 w, 2000 f/m, 71%; 5: 29 w, 1900 f/m, 68%; 4: 24 w, 1800 f/m, 64%; 3: 19 w, 1600 f/m, 57%; 2: 12 w, 1350 f/m, 48%; 1: 6 w, 1000 f/m, 36%. For comparison, another fan I have with a variable speed L to H controller, the lowest speed is 73% of the maximum. If you want a wider range of speeds available, particularly at the slower end, this fan is a fantastic option at an unbelievably low price. I have already ordered several others. Even if it fails in a year or two of nearly continuous use, it is still a great value. ... show more

    • Work great
Size: 6 Inch
We purchased these to use with our CO2 laser machines - and they work fantastically! We have one hooked up to each of our machines and then they are connected in together with a T connector to vent them outside. Our previous fume extractor system we had (which was MUCH more expensive) hardly extracted any of the fumes/smoke when engraving, especially on wood. These work great - we have VERY LITTLE fumes even when engraving wood! Highly recommend this item! ... show more

    • Don't waste your time. Fire hazard!
Size: 8 Inch
Was noisy from the start then got hot and started to literally melt down in less than 18 hours of use. Had to unplug to avoid a fire. Customer service is useless and is trying to say my grow tent is a fire source of some sort.
