BLACK+DECKER 9" Twin Window Fan with 2 Speeds, BFW9M, White | Dual Fan Heads, Mechanical Controls, Removable Legs, Fits Sliding Windows up to 33” Wide with Accordion Side Panels

Product Overview

The BLACK+DECKER 9‑inch Twin Window Fan is designed to provide airflow for two windows in a single unit. Each fan head is 9 inches in diameter, and the device contains two separate heads that can be positioned independently on a sliding window or two separate windows. The fan operates at two speed settings, allowing a user to choose a gentle breeze or a stronger flow of air as needed.

Key Features

• Dual 9‑inch fan heads – two separate 9‑inch fans are integrated into the unit for simultaneous use on two windows.
• Two speed options – a mechanical speed selector provides a low and a high setting, giving flexibility for different cooling needs.
• Mechanical controls – a tactile control knob on the unit allows the user to adjust speed directly without the need for a remote or electrical connection.
• Removable legs – the fan comes with detachable legs that can be taken off for storage or when the fan is not in use.
• Window compatibility – the fan fits sliding windows up to 33 inches wide, with accordion side panels that slide to adjust to the window’s width and seal gaps.
• White finish – the unit is finished in a clean white color that can complement a variety of window treatments and décor styles.

Design and Build

Each fan head is mounted on a central support bar that runs the length of the unit. The mechanical speed control is positioned on the bar, allowing quick adjustments from either side of the unit. The removable legs are bolted to the base of the support bar. When the legs are attached, the fan sits flat against the window, with the accordion panels extending to match the width of the sliding window. When the legs are removed, the unit can be stored on a flat surface or carried to another location.

Installation Process

Position the unit on a sliding window that measures no more than 33 inches in width. The accordion side panels on each side of the unit will slide along the window frame and seal the gap between the fan and the frame. Each of the two fan heads can be directed toward a separate window if desired. The mechanical speed control is used to set the fan to low or high speed once the unit is in place. If the fan is needed in a location with a single window, one of the fan heads can be used while the other remains stationary or can be turned to face the same window for a stronger breeze.

Operation and Maintenance

To use the fan, turn the speed control knob to the desired setting. The fan will begin to rotate immediately, drawing air through the central opening and across the window area. When the fan is no longer needed, simply turn the control knob to the off position. The unit can be wiped clean with a damp cloth to remove dust or debris. The removable legs can be detached by loosening the bolts that hold them to the base. For storage, keep the unit in a dry place and keep the accordion panels free from obstruction.

Applications

This fan is suitable for use in homes where a sliding window is present and a portable cooling solution is desired. It can be placed on a window to circulate air, providing a breeze without the need for an electrical outlet. The two fan heads allow for airflow across two windows simultaneously, which can be useful in rooms with multiple windows that need ventilation.

Additional Considerations

Because the fan operates via mechanical controls and does not require power from a wall outlet, it can be used in rooms where electrical access is limited. The white color provides a neutral appearance that can fit with different window coverings. The fan is a standalone device and does not include any additional accessories beyond the unit itself, the mechanical control knob, and the removable legs.
