Air King 20-Inch 2,140 CFM 3-Speed Box Fan #9723



"Air King" is no longer a "king" - just a ...Lasko
I have just recently bought this fan, based on my experience with my old fan that had propeller blades identical to depicted on all published images associated with this fan model. This shape of the propeller (with blades similar to elephant ears) is contributing to higher airflow, at the same RPM, vs. shape of propeller with blade looking like rabbit ears, and which is lately used on majority of inexpensive box fans sold under brand names Lasko or others.

To my surprise, the fan that arrived per my order, while having on the box a correct model number and image as on this web page, has propeller identical to less expensive Lasko brand box fans.

Lasko 20" Premium Box Fan 3-SPEED

In fact, Air King is subsidiary of Lasko, as I discovered while contacting the Air King.

In short, this fan went through a typical to current times "cost reduction reengineering" by someone who...

If you want a little more air and a little less noise at twice the price, buy it.
I ordered this fan because the blades looked a little more like the old box fans that you used to be able to get 20 years ago. Back then the blades were wider and had a steeper pitch. When they said 20" they meant the diameter of the blade, not the size of the box.

Well I was partially right. Compared to the Lasko 3733 that I own and some unknown model of a Lakewood box fan with nearly identical blades as the Lasko, it moves a little more air and is a little quieter. Noise is hard to characterize. To me the Air King is quieter because the noise it makes is at lower frequencies and is easier to ignore -- It's more of a "rumble" than the "buzz" you get from the Lasko and Lakewood.

Much of Air King's slight performance advantage is because it is a bigger fan. The Box is 21" and the blades are 20". The Lasko and Lakewood have 20" boxes and the blades are 19" Is it worth twice the price as the Lasko and Lakewood? Probably not, but there isn't much choice...

This may spark your interest!
This fan had only worked for one season then it sparked and I can smell smoke the next summer. I was very disappointed that it broke and almost started a fire. I bought it because it looked like the old fans. I have the Haier box fan that also looks like the old ones. This fan used to work really well but it wasn't worth it.
