The fan runs on standard 120 volts, consuming 630 watts of power, which is relatively energy-efficient for its size and performance. It operates at 825 rotations per minute (RPM) with a single-speed setting, which might limit its versatility in adjusting airflow intensity based on needs.

Installation is straightforward, as it is ready to be wall-mounted, but it lacks reversible airflow functionality, meaning it can only expel air rather than draw it in. The dimensions (5.75 inches deep, 39 inches wide, and 39 inches high) should be checked against your available space to ensure a proper fit. This fan is best suited for users with large areas that require efficient and robust ventilation, and who prioritize durability and straightforward installation over adjustable features or quiet operation.

Installation is straightforward thanks to expandable side panels that fit most standard windows between 25 and 32 inches wide, so it should work well in typical home settings.

The fan uses a 63-watt copper motor, which suggests reliable and consistent performance without consuming too much electricity.

Manual controls are simple to use, but for those who prefer remote or automatic options, this might feel a bit basic.
