Just take the 6 screws out of the front and back covers. Remove, clean, wipe down fan blades and re-assemble. Make sure the fan is unplugged of course.

Answers

Yes, I have mine sideways and it works fine. It really is not "mounted" in a window. It sets on the lower window sill and close the window onto fan. I moves a decent amount of air on low speed.

No. It needs to be standing. It is a great fan. Needs to be standing to have the best airflow.

Asked by JustMe July 8, 2018

Answers

Great question. Our box fans do not have a reverse setting, but we do manufacture a window fan that is designed to be placed in the window for this exact use. It has three settings on both intake and exhaust, and its model number is 2155A. It can be found here, if you are interested: https://www.laskoproducts.com/products/16-inch-electrically-reversible-window-fan-2155a/

Really good fans I got two of them they move a lot of air

Fan shakes and makes clicking noises
I got two of these. Both made terrible clicking sounds. I took the front off of one and put it back on and it was fine. Didn’t work on the other one. The plastic molding for the blade has a lot of rough edges, and in mine there was nothing keeping the blades from knocking against the front panel. A waste of money.

Good wind and versatile fan. Love having the weather sealed motor plus thermostat for in the windows during the summer. I have had them before and they lasted years and took me three years to find anyone that carried these fans again. Came with no damage and before delivery date.

I bought two: one was not working out of the box, it only had one slow speed. Thankfully home Depot took it back 23 hours later the next day. The working ones work great, but a couple of hundred more CFM on high would be good. I would recommend!

Installed these fans in 25H by 18W garage windows to pull in air from the shade. They work tremendously and the closed edges keep a tight airflow. Lightweight and the feet fit perfectly on the window sill.

The fan is on the better quality scale of the spectrum of the Lasko's product line. I like the metal frame and the weatherproof motor.

Beautiful Fan Worth the extra $$ for in/out window use
I have both this weathershield 20 inch box fan and a Lasko white standard model and notice the air movement difference. Just the gray and black make this fan look great and work well while placed in my large double hung windows to cool the house. I really like the optional thermostat if I just want it to run here and there or till I fall asleep. I have used this for a year now, in/out the window, but all year round in the Northeast and nothing has stopped it from working. I included a picture of the shielded motor with the rear grill off while I cleaned it. Great job Lasko on this model. A definite recommendation for people who LOVE box fans and their multiple usages. As others have stated I do wish there was a speed adjustment to the thermostat. Currently, it will just shut off and on to the speed dialed in. Also, not a model specific concern but just a Lasko design is to rethink the plastic stability feet. They do not last long and I have had to make something metal to last longer on all my Lasko box fans.

Purchased as a replacement for a 8+ year-old LASKO built-in to an outdoor playhouse. Exposed to rain and sun, the unit still operated but was rusty and the plastic was degrading. The new unit was identical in dimension and utilized the same on/off arrangement. Color and finish was retail quality. Noted that the frame has additional mounting screw holes hand-drilled under the plastic grilles. No clue if this was a factory correction, but it does not harm it's appearance or performance. Auto on/off and long-lasting motor make it perfect for my application.
