This twin window fan provides flexible airflow options for different rooms and weather conditions. It supports 3 directions of airflow: cool mode with blades directed inward to bring fresh air in, exhaust mode to remove stale air, and circulate mode with opposing blade rotation to move air across the room. The unit offers 3 speeds: low, medium, and high, so you can dial the breeze to a gentle level or a stronger cooling effect. An expandable panel adapts from 23.5 in. to 37 in. accommodating a range of window sizes and locking securely in place for stable installation. For portability and placement variety, the fan includes built in carrying handles and detachable standing feet, enabling easy motion between rooms or stable use on a tabletop surface. The power setup uses standard household voltage and is designed for safe operation, with electrical components arranged for reliable performance. A foam seal strip helps create a tight seal between the fan and the window frame to maximize airflow efficiency and reduce leaks, while a removable cover and a bug cover offer protection and simple maintenance. The package also includes a foam tape and other basic hardware that support proper setup and fit. All components are sized to fit common window configurations and can be deployed without specialized tools. Color: White.
