With its powerful mixed-flow design, this inline tube fan delivers an airflow of up to 405CFM, easily meeting large ventilation and dehumidification requirements.
  • Temperature Humidity Smart Controller: The small controller that integrates speed control, temperature control, and humidity control. It provides multiple operating modes, such as auto, high temperature, low temperature, high humidity, and low humidity, along with 10 speed levels. The included ambient probe can automatically monitor and regulate humidity and temperature, ensuring optimal ventilation in your grow room.
  • EC motor: The EC motor built into the tube fan is designed for energy efficiency, quiet operation and a long service life. This EC motor is low maintenance and operates smoothly in various voltage and frequency environments, making it suitable for a wide range of power environments.
  • Durable: This duct fan bathroom fan is made of a robust plastic housing with an IPX4 rating to keep out dust and liquids. Designed to withstand harsh environments, it comes with a long 2.5mm power cord with Euro plug for easy installation and hanging in any tent area.

OPTIMIZE CLIMATE WITHSMART CONTROLLER
  • EC duct fans with motor drive: High energy efficiency, precise speed control, intelligence, low maintenance requirements, and quiet operation.

  • High-pressure fans can overcome resistance in ventilation systems and ensure that air flows over long distances and in complex systems. Duct fan HI-PE (6 inches) can achieve an air pressure of up to 583 Pa.

  • The Smart Control interface is DC. When connecting, the round head of the Smart Control must be firmly pressed down, and the plug needs to be pushed down with a bit of resistance.

I'm not sure where to start on this. Maybe how quiet it is, even on full blast. It's very quiet. Or maybe how much air it moves. It blew a bunch of papers off my desk when I first powered it on to play with the included controller. Oh, yeah, the controller. That thing has some great features such as humidity sensing, temperature sensing, or even tailored airflow based on the temperature that's being read by the probe. This is being used to help boost some air conditioning to a second-floor choir loft where the air flow just doesn't quite get there, and so this can help to alleviate that based on the temperature up there on the risers. The quietness makes it a huge plus because the choir is recorded, and the less post-processing on the audio that has to be done, the better. Overall, I'm super-impressed with this!

This fan really moves the air. I am using it to blow on my seedlings so they grow strong. I have found that if there is no stress on the seedlings (no wind blowing), they grow "leggy," which is weak, thin and tall. The air blowing on them makes them strong and they grow thick stems. My only complaint about it is that it is very loud. Very loud. It moves a lot of air. It has controls to adjust the fan speed and a temperature/humidity controller. But it is loud. That's why I gave it 4 stars instead of 5.

I am using this as an exhaust fan for my laser cutter. This means that when I need it, I just need it to run at 100%. I don't care about temperature or humidity, just volume of air (smoke) moved. I was very happy to find out that without the controller connected, the fan runs at 100%. It moves more air than the fan that came with the cutter and it is quieter which is exactly what I was looking for. It mounts easily and is very compact. It works perfectly for my use case. The only improvement that I can recommend is to put an airflow arrow on the fan casing.Since I didn't use the controller, my review is just for the fan.

Small in size but not in power! This thing moves some serious air on 10. Love the included sensor, has a nice long wire to run it wherever you want. Also love the included screen and control unit. Also a long cord so you can place that wherever also. Using this in my air return to constantly bring air upstairs in a two story house. Working PERFECT. Highly recommend.

I installed this in my grow tent, and it works perfectly. It’s quiet, even at high speeds, and the smart controller is super handy. You just set your temperature and humidity and it runs automatically. The setup was quick and it feels like a good quality piece. It moves a lot of air without sucking up too much power. Recommend this to fellow growers, or to anyone looking for good air circulation.

Good fan to use on a 6" duct extension on my AC system. The vent is all the way at the end of a long run and the air trickles out. Adding the fan in the soffit where the extended duct is helps to reduce the noise and the increase in airflow is perfect. As the Soffit is in a closet, I was able to mount the controls on the outside and set it to come on only when the temperature drops below 60F as that would be when the AC is running. Perfect for the summer. The heat is rarely used here but if I need to, I can adjust the controls easily enough.

This ultra powerful inline fan is super high quality and is very quiet even on its maximum setting. It can push air for over 30’ with ease and that’s only on the medium setting. I mounted the temperature sensor and it kicks on and off automatically without any issues at the desired temperature. The fan was easy to mount with the included kit, and only took a few minutes to replace on my indoor terrarium. My favorite feature is the wall mounted digital display. It’s the brains of the operation and allows you to adjust the temperature, fan speed, and much more. The LCD is easy to read with large numbers making it easier to read at distance or if you just have bad eyes. Now I just need another one to setup on the other side and my system will be complete.

I received the Hon&Guan 6 Inch Inline Duct Fan just in time for another round of Texas heat, and it’s been a reliable addition to my setup. The smart controller makes it simple to dial in the right temperature and humidity levels, so I don’t have to babysit the system when the weather swings. The 405 CFM airflow is more than enough to keep my garage comfortable, and the fan runs quietly, which is a relief since I spend a lot of time out there tinkering.One afternoon, I used the fan to ventilate my grow tent while working on a small hydroponics project. With the smart controller, I set the target humidity, and the fan kicked in automatically when things got muggy. This hands-off approach let me focus on my plants without worrying about overheating or excess moisture.Compared to some other fans I’ve tried, this one doesn’t come with Wi-Fi or app connectivity, which might be a downside for folks who like everything smart-home integrated. For me, though, the physical controls are straightforward and dependable-less fiddling, more doing.
