Air King 9166 Window Fan 3560 Cfm 20 Inch 3 Speed

Product Description

The AIR KING 9166 is a single-unit window fan built for high-volume air movement in residential and light-commercial applications. Equipped with a 20-inch blade, it delivers up to 3,560 cubic feet per minute (CFM) of airflow, making it effective for whole-room ventilation, exhaust, or fresh-air intake. The fan operates on 110 volts and draws between 1.8 and 3.2 amps depending on the selected speed. Three speed settings allow the installer or end user to balance airflow volume against noise and power draw. The unit weighs 36.04 pounds, indicating a solid, durable frame suited for sustained window installation.

This fan is designed for window-mount installation in residential bedrooms, living areas, workshops, and utility spaces where mechanical ventilation is needed without a permanently ducted system. It is commonly installed by HVAC technicians, general contractors, or experienced owner-operators in single or double-hung window openings. The three-speed operation makes it adaptable to varying ventilation loads throughout the day.

Installation Notes

Install in a window opening that can support the unit's weight and provide a secure, draft-free seal around the frame. Ensure the mounting surface and window sash are structurally sound before securing the fan. Disconnect power at the circuit before any wiring connections and verify the branch circuit is rated for the fan's amp draw at the selected speed. Follow local mechanical and electrical codes for ventilation equipment installation.
