Although Sunbeam window fans are resistant to light rain, if your fan gets wet, we recommend you to unplug it and let it dry before plugging it back in for use.

All window fans have an enclosed motor which will allow you to use your fan safely when it is raining. However, we advise that you remove your product from the window during heavy inclement weather as powerful winds could blow water into your home.

No, box fans are not designed with window use in mind. Since they do not provide the secure fit of a window fan, they are more likely to fall out of the window. Box fan motors are also not designed to be rain-resistant, as are those of window fans.

Window fans can be installed either vertically or horizontally. Please note when installing vertically, the internal adjustable extender panel must be located on the top of the window fan and never on the bottom.

Sunbeam window fans are designed specifically to fit virtually all windows. Sunbeam window fans have special features for this purpose, such as extender panels and windowsill holders. Installation of our window fans is designed to be quick and easy, with no tools required. Options available on window fans include the following: electric reversibility for air intake, air exhaust, or even air exchange; thermostats; digital thermostats; temperature displays; and sleep settings for quieter performance at night. Thermostats are particularly useful on window fans, as most people tend to use this type of fan in their bedroom. You can set the thermostat to your desired comfort level. The thermostat will then automatically turn the window fan on or off, in order to maintain your set temperature. This feature is especially welcome in the fall or early spring. As the night air cools down, your fan will turn off, and then turn on again as the morning sun begins to warm your room.

Extender panels can be used to fit window fans into both horizontal and vertical positions. They slide into the right side of your window fan to allow for a tight fit in your window. Sunbeam window fans are made using patented Slider Safe® extender panels, which are designed to provide stability in the vertical position used with a slider window.
