Review: Essential Addition for Better Airflow in Keystone RVs - The VIVOSUN 4 Inch Inline Duct Fan with 100 CFM is an absolute must-have if you own a Keystone RV, especially models like the Avalanche 390DS. The lack of proper airflow in the HVAC system of these RVs, particularly in the rear bedroom, can make it unbearably hot. Keystone's quality control issues only add to the frustration. Installing this ventilation fan was straightforward, and the difference in airflow is night and day. The rear bedroom now receives proper air circulation, making it comfortable even on hot days. The fan operates quietly, which is a bonus, ensuring that it doesn't disturb your peace. For anyone dealing with similar HVAC issues in their Keystone RV, I highly recommend the VIVOSUN Inline Duct Fan. It's a reliable solution to prevent overheating and improve overall comfort. 🌬️🚐❄️
Review: Quiet exhaust fan - I used this fan along with an old kitchen vent hood to make a ventilation fan for my workshop. It was easy to install inline, and I wired it up to a switched outlet. Now, when I do woodworking or painting in the shop, the dust and fumes are drawn through a common furnace filter and vented outside. Although the volume of air moved is not great, it does help keep the air cleaner, without generating excessive noise.

## Questions & Answers

**Q: Can you hook up a speed control to this booster?**
A: No you do not want to use a speed controller. You will burn this motor out in days. You want to use speed controllers on centrifugal fans, not booster fans. The motor is ment for the rated voltage, nothing more nothing less. Please don't listen to the comments saying speed controllers are compatible with this booster fan.

**Q: Would this fan properly vent a 1000w hps lamp?**
A: I am cooling two 600 W HPS lamps with a single fan and it works well

**Q: Will it overheat with a flow blockage?**
A: Very small motor like a bathroom exhaust fan. Will not overheat because not an air tight situation.

**Q: I could definitely hook this up on a timer, but is it okay if the fan happens to run when the AC is not? (Context, booster for one of my bedrooms)**
A: If the AC fan is not running,  the duct fan will *tend* to draw air from registers in other rooms rather than through the idle ac unit.  So, it will still work to equalize temperatures between rooms,  which is likely your goal.   On the negative side,  it will be drawing from the ceilings,  the hottest part of the rooms.

### ⭐⭐⭐⭐ Not strong enough to open my dampers
*by K***F on February 26, 2026*

The fans work fine, but because they are low CFM, they won't open my butterfly dampers. I had to step up to stronger fans. These aren't terribly noisy, so if you aren't using dampers that require air flow to open, they're a good, affordable choice.
