My original 6-inch stock bathroom fan, although working okay, was very noisy and didn’t quite evacuate the bathroom as well as I would have liked.

I installed the Heng’s Vortex II 9-inch fan because it provided 300-percent more airflow, was quieter, and had three forward and two reverse speeds to greatly increase air movement without the need to touch the roof for installation.

Bathroom Fan Remove Outer Shroud

Four screws easily removed the outer flange, then another two removed the inner flange and screen, and a single screw removed the crank handle.

After that, the old fan motor was removed and the mounting bracket was taken off using a Dremel tool and pliers.

Then I noticed that the outer flange was starting to yellow, so I whitened it using Salon Care 40 and let it set in the sun for a few hours. It worked well.

Installing the new fan was easy; essentially like removal in reverse.

The same screws were used and the wiring was easy with the black and white wiring connecting in the same places.

The Heng’s Vortex II fan works great! Having three forward speeds allows for quick and efficient evacuation of the bathroom, and the two reverse speeds allow us to push air into the bathroom to dry our towels and the tub quickly. What I also like is this mod didn’t require any roof modifications and the fan is quieter.

It took me three hours to complete this modification and cost me $150. In my opinion, the skill level of this modification is medium.
