## Description

Product Description Maintain a comfortable temperature indoors with the Holmes Reversible Twin Window Fan. Designed to fit most double-hung and slider windows, this double window fan takes in fresh, cool air from the outdoors to provide cooling comfort. Each of the unit's two fans can be independently reversed, allowing you to intake fresh air, exhaust stale air, or exchange air for full-room circulation. Featuring two speed settings and a one-touch programmable thermostat, the fan lets you easily adjust airflow in accordance with your personal comfort level. Water-resistant motors make the fan safe for use during rainy weather. And thanks to its adjustable extender screen and extender panel, the fan can fit securely in a wide range of window sizes. Control the thermostat and 2 digital comfort settings with the 1Touch controls. It's in with the good air and out with the bad air with the Holmes® Electronically Reversible Twin Window Fan . This window fan operates quietly and efficiently by taking-in fresh, cooler, outdoor air and exhausting stale, warm, indoor air for cooling comfort. desertcart.com This double window fan draws in fresh, cool air from the outside or exhausts stale, hot air from inside. It can also do both simultaneously, because each of the two fans can be set independently to draw in or exhaust out, allowing the unit to exchange inside and outside air. Operable either manually or automatically--with its thermostat turning the fans off and on to maintain a selected temperature--the unit has a one-touch electronic control and two speeds so it can be adjusted to conditions. It's designed to fit double-hung, vertical-slider, and casement windows. A built-in 7-inch extender and extra 3-inch extender permit custom fitting for windows from 24 to 37 inches wide. Because the unit is lightweight plastic it can be moved easily from room to room. The fans have six blades and measure 8-1/2 inches in diameter. Overall, the unit is 12-1/4 inches high, arrives fully assembled, and carries a three-year warranty against defects.

## Questions & Answers

**Q: I want to use this in a stand-alone one room dance studio with only one window. If it's very hot outside, will this really keep it cool inside?**
A: It’s not an AC unit so it will only be as cool (or slightly less hot) as the air from the source. That being said you could use this fan on Exhaust to suck hot air out and use a tower fan to create a breeze in the room. But to cool a room on a 90+ degree day, I’d recommend a window AC. This fan will circulate air tho, so it’s not a bad place to start.

**Q: Can you use the fan without the thermostat feature? I don't want it going on and off all night long.**
A: I think the other replies were with older models? I just purchased this model and there's no issue with opting out of the thermostat feature.  As noted in the instructions, to get to continous air flow, you just keep clicking the button through the modes (first you click throught the various thermostat temperatures, and then you get to "high" or "low" as options.  If you click high or low either one will stay on continously. Both options are extremely quiet. It sounds like the person who had a louid nose on the low setting had a defective fan.

**Q: how many CFUM**
A: The CFM rating for this fan is: Hi:410 +/- 20;   Lo: 320 +/- 20

**Q: Can this fan be turned on it's side?  My window is only 22" wide but is 36" high.**
A: I think it would be possible.  My only concern would be stability.  The top of the fan is about 2" wide which helps anchor the fan into place when the window is closed.  The sides are much thinner and I would be worried about the fan tipping over or the sides possibly cracking b/c they are flimsier.  That all being said, you could certainly McGyver it into working out.
