The 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 24 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.

Vornado creates cutting edge products - so when we set out to create a window fan, we did our research and then rewrote the formula. The result was just over 6" tall, unobtrusive and clever enough to be seamlessly installed in windows from 24” up to 38" wide using an innovative modular block system. Its electronically reversible chamber smoothly brings fresh air in or exhausts stale air out. Rain or shine, the weather-resistant casing doesn’t mind. Either way, you’ll still enjoy the view.

I purchased the Vornado Portal Low Profile Window Fan for our nearly 200-year-old farmhouse, which does not have central air conditioning, and it has made a noticeable difference in keeping the house comfortable. One of my favorite features is the exhaust mode, which does an excellent job of pulling hot, stale air out of the house, especially after a warm day or when cooking. The low-profile design fits nicely in the window without being bulky or obstructing the view. It was easy to install, and the controls are straightforward to use. The fan moves a surprising amount of air for its size and helps create a refreshing breeze throughout the house when paired with an open window on the opposite side. For older homes that lack air conditioning, this fan is a practical and effective solution. It helps cool the house naturally, improves airflow, and makes summer days much more manageable. I'm very pleased with this purchase.. Abbey. Pennsylvania. Thu Jun 11 2026

The 2-speed motor efficiently pulls cool air in or can exhaust stale air out of rooms. No tools are needed to install the fan to the window. Automatically control the ventilator via a thermostat. LED display allows for full control over the dual fans and the direction they spin.
