Mixed flow design combined with an EC-powered motor for a truly quiet and energy efficient performance. Duct Size: 6" | Dimensions: 7.9 x 12.6 x 8.4 in. | Airflow: 352 CFM | Noise: 34 dBA | Bearings: Dual Ball Product Description This inline fan system packs the CLOUDLINE’s core innovations and premium build quality together to bring you a value package. Designed to quietly cool grow tents, rooms, and closets, and provide ventilation in various air circulation and exhaust projects. Containing an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one inline fan unit, one speed controller, UIS to 4-pin Molex dongle, installation manual, and all necessary mounting hardware. Precise Speed Controller The speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. This inline fan is equipped with the CLOUDLINE Series’ same EC-motor that is precisely controlled using PWM (Pulse Width Modulation), which enables it to run smoothly at extremely low RPM speeds without generating motor noise. Ten speed options are available with power switch and backup memory. This model can be connected to the following smart controllers to share the same programming and power source as other EC-motor CLOUDLINE fans: B-Series Temperature Controller T-Series Temperature and Humidity Controller CONTROLLER 67 Quiet and Energy Efficient Design The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. In addition, the inline fan is crafted with a plastic mounting base to diminish noise as a result of fan vibration. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments. Applications This quiet inline fan system is most found in hydroponic grow tents and rooms to provide cooling and ventilation for plants. Its low noise and advanced control features make it fit for bathroom and attic settings, as well as cooling AV equipment rooms, closets, racks, and cabinets.

## Questions & Answers

**Q: What is the length of the speed control cord?**
A: 5ft
It look like an USB-C so maybe you can extend it.
When disconnecting the remote the fan goes full speed, then back to previous setting when you reconnect it.

**Q: How long is the adapter to use with the digital controller?**
A: approx. 10 to 15 ft long

**Q: One user stated that they wired directly to furnace blower, hence when blower comes on, it turn on, How? Any info please?**
A: This is my plan for this product. You could do this in two ways. Assuming your HVAC furnace blower is the same voltage, 120VAC in the US, you could wire directly off the feed inside the furnace that powers the blower. This will require understanding of electrical wiring and/or electrical schematic of the furnace. Although unlikely, this method may overload the blower protection circuit and probably voids the furnace warranty. Alternatively, you could use the house thermostat fan signal to control a 24 VAC relay, such as Functional Devices RIBU1C, to switch the 120 VAC powering the duct fan.

**Q: Any way to make it just go on full power instead of having to to push the button 5 times?**
A: Push the button 5 times. 
The controller is set up to program fan speed on start up but will maintain the memory on a power loss event. 
If you don’t want to push the button 5 times then just unplug it. Then you can plug it in one time🤔

### ⭐⭐⭐⭐ Works but don't like USB controller
*by A***R on 27 October 2025*

I like the strong steel blades and looks like they have been balanced with attached weights. The housing is plastic that is deformed in sections. I wish the USB controller was a knob for fastest control, not a button that you have to repeatedly press and watch the led lights. I wish I could just wire in a normal toggle switch that remembers last speed. It's fairly quiet on the low setting but gets quickly loud as you increase the speed.
