Optimus - 8" Electrically Reversible Twin Window Fan - White

Transom is the result of a complete re-imagining of what a window fan should be. The air chamber abundantly draws fresh air from the outside in — or reverses electronically to exhaust stale air out. Powerful airflow circulation and comfort at half the height of conventional window fans, Transom is easy to install, blends elegantly into the space and preservesyour view. Transom seals off windows 26” to 40” wide with the patented Soft-fit System that provides a sleek, satisfying and snug fit from end to end, without having to remove your screen. Transom – a new kind of window fan.

The Lasko electronically reversible twin window fan will keep you cool both day and night. Two independently-controlled motor fans operate in three ways - intake to bring in fresh air, exhaust to push out stale air, and exchange to combine both operations. The digital thermostat senses room temperature and turns the fan on or off automatically to maintain the comfort level of your choice. It fits most windows (double-hung, casement or sliding) from 22 inches to 32 inches. The expandable panels of this fully assembled unit provide a custom fit for your window space and the slim profile ensures that the outdoors is still within view.
