Pros & Cons

Update Pros and Cons
The AI used to provide these results are constantly improving. These results might change.

Pros

Much louder than your standard bathroom fan but totally worth it! Does a nice job equalizing the temp. This moves enough air to keep moisture out and reduce the inside temps down to a reasonable level.


Cons

Not a demanding application at all. Did not install. Was not impressed.

Fan blade is too small to move a column of air. Not close to the 100cfm rating.

Quality

The rear bedroom now receives proper air circulation, making it comfortable even on hot days.

Installing this ventilation fan was straightforward, and the difference in airflow is night and day.

Performance wise, this thing is fairly loud and i do not believe it's moving around 200 cfm rather than the claimed 400.

The lack of proper airflow in the hvac system of these rvs, particularly in the rear bedroom, can make it unbearably hot.

Price

Ultimately, it does what it's supposed to do at a very affordable price.

    The vivosun 4 inch inline duct fan with 100 cfm is an absolute musthave if you own a keystone rv especially models like the avalanche 390ds

    I bought this to duct fan to replace a much more expensive and powerful fan that stopped working

    Posted by a reviewer on Amazon

    Out of the box the nut holding the fan blades to the drive bolt and the screws holding the motor to the support were all extremely loose

    Posted by a reviewer on Amazon

    I had to tighten everything to keep the blades from rubbing on the inside of the housing

    Posted by a reviewer on Amazon

    That said im going to buy a replacement of the original fan 4x the cost of this one since it moves much more air with less noise
