Air King 9155 Reviews

Rated 5 out of 5 by from Excellent ventilation option This fan is well conceived and moves a lot of air quietly. The quiet is due to the large blades that can turn slowly while taking a deep bite. This is much better than small fans that must turn much faster to generate the same flow volume. This makes it a great solution for the living areas of a house. A lot of the key parts are plastic which should provide protection against corrosion and the size will fit into most windows. This fan was purchased as part of a testing protocol for a new product (that my company manufactures) that controls any ventilation fan automatically so that it always operates at maximum efficiency. The comments above are based on evaluation of a variety of products.

Rated 4 out of 5 by from Good Fan This is a good fan, much more powerful than regular window fans, or standing fans, however it is not powerful enough to combat 90+ degree days. Our house is 850 sq ft. and I don't feel the draw I was expecting and we can't rely on it to replace AC on hot days. Although not nearly as powerful as the old, unfailing window fan that my grandparents use (25+ yrs old) to cool their 2000 sq ft home, it fits our small window and is really our only option since we don't have attic access or room for anything larger. So with those considerations in mind it is perfect for our situation.

Rated 5 out of 5 by from Air King 9155 Works as advertised. I have installed this fan in a 1300 Sq. Ft. Apartment. The fan on high speed measured 60 db with my sound pressure meter. You can still hear the TV @ moderate volume but you can deinitely hear the fan. Medium speed significantly reduces the noise level to 50 db and low speed is whisper quiet. I close all the windows except the bedrooms and draw cool air from outside after the temperature cools outside. The bedrooms cool and I can finally sleep at night during the summer. It takes about an hour for the rooms to be comfortable if the temperature outside is below 24 degrees celsius. 75 degrees F for my American friends. You can feel a cool breeze from the outdoor air and measure it with a 6" strip of toilet paper. The TP angles at about 45 degrees with the airflow. The casement windows are 19" x 39" for anyone that wants to do the math. I figure the air exchange is roughly every 7 minutes with the fan on high speed. The fan is not a solution for daytime use when temperatures are hot or exceed the inside temperature. I cool the apartment down at night then close the windows and blinds until the temperature inside exceeds outside then open things up and run the fan. The bedrooms used to stay above 27 C, 80 F and wickedly uncomfortable prior to installaion of this fan. On a cooler night I have to get up and shut the fan off as it's too cool. Hmmm Air King a thermostat shut off would be a nice addition. It is installed in a casement window. (The ones that have lever handles and open outward like a pie.) I removed the sliding expanders and installed spacers. 1 1/4" diameter Poly pipe ends matching the height of the plastic shroud. Mounted high strength Velcro stickies to the spacers and the other side to the casement window frame. I then filled the remaining space with and Optix (plexiglass)pane (mounted with velcro in the corners) to ensure reasonable air tightness at the mounting window. At the end and sides I installed screen mounting hardware into the plastic window frame for 3 mounting points to ensure the fan would stay in the window. Velcro alone wouldn't be able to fully hold the weight. The Fan can be removed and installed in seconds using this methodology.

Rated 5 out of 5 by from Great house fan for a smallish house My parents had a house fan when I was a kid, and since running fans is considerably cheaper than running air conditioning, I talked my husband into getting one. I was concerned about the window size required, since our windows are not quite that big, but this was the smallest whole house fan I could find. It fit fine. The top of the plastic case goes over the window but all moving parts are in the opening. We usually run it at night and turn it off during the day to keep our second floor bedroom cool. I am very pleased; it works well and was easy to install (for two very unhandy people). Since we got it, my husband has gone from dubious that it will work to encouraging his parents to get one.

Rated 5 out of 5 by from great product... Very easy to install and works great. The power is amazing. I put this on the kitchen window and now when the fan is on the kitchen odor does not leave the kitchen. On the downside, it is a little noisey. But I don't mind since it does an excellent job. The workmanship and build quality appear to be OK but will take time to judge.

Rated 4 out of 5 by from Excellent fan for cooling the entire house. This fan does a great job of cooling an 1100sqf townhouse. It is loud, but sitting 15' or so away, it quickly become background noise. I only gave it 4 stars because of how flimsy the plastic housing feels. Mine has not broken, but it feels like will in a few too many situations.

Rated 5 out of 5 by from AIR KING 9155 Awesome product. I would have preferred the Air King 9166, but it would not fit our window. But, the 9155 works very well too, It just doesnt move as much air. When you crack a few windows open, say a couple of bedroom windows about 2-3 inches, it really pulls in the cool night air, especially in a newer home. Definitely recommend this product and Venting Direct. FAST SHIPPING!

Rated 4 out of 5 by from Keeps us comfortable This fan does a good job of exchanging the air in an 800 sq ft apartment. It has enabled me to not have to buy an air conditioner even though the temperature has been in the 90s and 100s. The only demerit is that the installation method does not go with the material of the window frames in the apartment. Venting Direct had faster shipping than other web options and it was the same total price.
