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
or Ask a Question
Can this go on a low flow all time, and them increase if measuring humidity higher than preinstalled
Answer This Question
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.

Good quality product
They seem similar to AC Infinity but much cheaper. Can move quite a bit of air. They regain the power setting after losing power. Happy with my purchase so far!

Highly recommended for its superb performance and great value!
I recently installed the VEVOR 4 Inch Inline Duct Fan HVAC Exhaust Blower, and I'm very impressed with its performance. Here are some key points from my experience: Pros: Effective Ventilation: This fan provides strong airflow, making it perfect for improving air circulation in my grow tent and basement. It effectively removes stale air and odors. Quiet Operation: Despite its powerful performance, the fan operates quietly, which is a huge plus. I can hardly hear it running, even in quieter settings. Sturdy Build: The fan is well-constructed and feels durable. The metal housing adds to its longevity and reliability. Easy Installation: Setting up the fan was straightforward. The included mounting brackets made it easy to install in my duct system. Compact Size: Its compact design means it fits well into tight spaces without any hassle. Cons: Short Power Cord: The power cord could be a bit longer, but it's not a major issue if you have an extension cord handy. Single Speed: It has a single speed setting, so if you need variable speed control, you might need an additional speed controller. Overall: The VEVOR 4 Inch Inline Duct Fan is a solid choice for anyone looking to improve their HVAC or ventilation system. It's powerful, quiet, and easy to set up. Highly recommended for its superb performance and great value!

Mr
I am using it for ventilating the bunks in the boat. Before we used Japsko product for €300 and it was shaked I have to change every 2 months. This VEVOR ventilator works non-stop for 3 months already and no issues with it.

Decent fan
Fan seems powerful enough without being overly noisy. The one I ordered has a \"smart\" controller, but I'm using it in the manual mode and controlling the power with a relay. There was a loose screw tumbling inside the fan (possibly an extra from the orange side cover), but it came out when I was inspecting it.
