Denali Aire 2DAFW9 Reversible Twin Window Fan 9 Inch

Product Description

The DENALI AIRE 2DAFW9 is a reversible twin window fan designed for residential ventilation in standard single- and double-hung windows. The unit houses two 9-inch fan blades and delivers three selectable speed settings, giving installers and end users precise control over airflow volume. A built-in digital thermostat allows pre-set temperature activation so the fan cycles automatically to maintain a target room temperature. The weather-resistant housing is built for continuous window-mounted operation, and the expandable accordion side panels compress or extend to seal the opening and minimize air bypass around the unit.

The 2DAFW9 is suited for living rooms, bedrooms, and offices where forced-air HVAC is absent, undersized, or supplemental cooling is needed during mild weather. The reversible fan function allows the user to switch between fresh air intake mode and exhaust mode without removing the unit from the window, which is useful for purging stale air or drawing in cooler evening air. A wireless remote control is included for mode and speed changes from across the room.

Key Features

• Twin 9-inch fan blades with three-speed airflow control
• Reversible operation: switches between intake and exhaust without window removal
• Digital thermostat for automatic temperature-based fan activation
• Expandable accordion side panels for a snug fit in varied window widths

Compatibility

Designed for installation in standard single- and double-hung residential windows. Accordion side panels allow fitment across a range of window widths typical in residential and light commercial applications.

Installation Notes

Installation is a general homeowner or light-maintenance task, though HVAC or facilities technicians may install these as supplemental ventilation in residential or light commercial spaces. Ensure the window sash closes firmly against the top of the fan frame and that accordion panels seal flush against the window frame on both sides to prevent air bypass. Unplug the unit before adjusting the panels or performing any cleaning. Follow all applicable local building codes regarding window ventilation and fall-prevention requirements when installing in upper-story windows.
