Air King High Performance Bath Fan

Bought the 90 cfm/2.5 sones unit to replace the builder's grade 50 cfm/4+ sones. The additional airflow was noticeable and the noise wasn't - just what I needed.

The frame is all plastic, which means no rust, though seeing how the bracket, motor, and motor mount is steel, I wouldn't place too much value on that aspect. The box is more rigid than the typical bent steel box, however, so there is value in that - no rattles.

Installation was a snap - literally. These units have a separate bracket that you screw into the joist, then snap the unit into place from below. It's much easier than the usual small-flange-at-the-edge mounting that other units use. Indeed, I spent less time installing this unit versus removing the old (working in a cramped attic space, nails to pry out, etc.) A plastic grommet and 3 wire nuts are included too - a nice touch.

The included materials note that ventilation fans have a 5 year warranty, not just a 1 year, so...Read more

It took me less than 2 minutes to remove the old fan and over 2 hours to install this Air King. I am very happy with the quiet, functional fan but the design of the fan made for a difficult installation.

The design of this fan could have easily been slightly different and allowed for a much easier installation. After cutting a minimum size hole, I was unable to maneuver it from above or below and get it into the snap bracket. I finally found that if I remove the connector from the body that hooks up to the hose it can be inserted from below, but you still have to go into the attic to re-attach the hose connector and hose.

Had the connector been directed away from the bracket instead of to the side, it is possible it could have been installed completely from below.

Now that it's installed, I do enjoy this Air King fan. The air exhaust is superior to what I had before and much quieter. It is an excellent fan.

Yesterday I received the AirKing bath fan and decided to install it right after work. I had an old air king from 1967 which had to come out. That took me 2 hours and a mess to do. Then I realized that the original duct was only 3" in diameter while the recently purchaced AirKing was 4" in diameter. I picked up a 4" to 3" converter and snaped the whole thing together in 30 minutes! No more loud noise. I'm very happy with the New AirKing!
