About this item

  • Universal Applications: Take a deep breath and relax. Our inline duct fan is specially designed as an exhaust for heat, humidity, and smoke, improving airflow in air planting tents, hydroponic planting rooms, electronic equipment rooms, kitchens, basements, etc. Get ready to go with the flow.
  • Blow Your Worries Away: Our inline fan provides a sufficient airflow of 205 cfm, enough to handle wide areas of ventilation and dehumidification, maintaining clean and fresh air circulation in dry environments all the time. Take control of any environment confidentially.
  • Power in Silence: Are you tired of loud, obnoxious ducts? Well, get ready to work in silence! 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.
  • Take It Easy: VEVOR's inline air duct fan adopts a smart controller. You will freely switch the ON/OFF/TIMER/AUTO modes (High Temperature; Low Temperature; High Humidity; Low Humidity). 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.
  • Everything You Need: To save time and costs, we provide a 4-inch inline fan with stainless steel clamps, hang-up slings, and non-vibration rubber mats and straps, allowing you to effortlessly complete installation. Additionally, you are not restricted in how you install the high-quality duct fan. Choose between hanging it or mounting it on the wall.

Questions and Answers
23 Questions
Can this go on a low flow all time, and them increase if measuring humidity higher than preinstalled
This controller operates according to the initially set flow rate, and the gear position can only be adjusted manually, and will not change due to changes in temperature and humidity.

6" Inline Duct Fan
I got this to use with my 40W Laser system. It does an awesome job removing the smoke from the enclosed work area of the laser.

These fans are heavy duty and as good or better than the higher priced ac infinity fans. These do the same thing at a much lower cost. I'm recommending These fans to all the indoor grow tent flowering rooms.

About half the price, but all the performance.
Simply put, this inline duct fan seems to be as good as any of the competing brands, and makes one wonder why the others cost so much more. The only issue I had was a loud high-pitched whine that came from the controller box even when the fan was completely off. (Since the controller monitors temperature and humidity, it's never really \"off.\") Then I got around to plugging in the temperature sensor cable (which not all competitors provide or support), and the whine disappeared completely. I guess some circuitry was switching on and off to check temperature, and with no sensor it made an audible switching sound. In any case, this is a flexible controller and a fully functional fan, and I can't find any fault with it. And it has an anti-back-flow feature so outside air doesn't blow back into the duct when the fan is off. Mine is installed on the high-pressure side of the shop, and there's almost always prevailing wind against that side of the building, but no indication of any draft back through the fan. This can be very important, not only to prevent heat loss, but also to prevent possibly toxic dust and particulates that accumulate in the duct from being blown back inside. I will definitely pay attention to other products from Vevor.

Mr
This has been a great fan Best one so far that we have bought and we've checked out several different companies
Sean Sean
Pretty good
Fan works well, blows/sucks a good amount of air. Fan temp controller also works fine, lots of options on when to turn the fan on/off. I wish it had the option to ramp up the speed over a temp range. To be fair you can set the speed it goes on to, but it won't raise the speed if your temp gets too far above the set temp. The fan has 10 speed options, but the auto on/off only can turn it on and off. It cannot adjust whatever preset speed you picked based on the temp.

Mr
Excellent, it's been running in my damp basement continuously for several days. Moving the moist air outside through my chimney vent of the same size diameter vent. My air quality in my basement has improved greatly, allowing me to work in the area.

This thing moves a lot of air. It is a little noisier than I hoped for but it's not a really big deal.
Spider Spider
Works good
Would work well for a solar panel fan. I use it to vent air out of my basement right up the old chimney pipe. You can set the temp or humidity you want. Easy installation. Easy to understand. 4 out of 5 stars because it took 2 and 1/2 weeks to get it and you can't cancel your order once you place it.
