AC Infinity CLOUDLINE A6 6-Inch Inline Duct Fan

The CLOUDLINE A6 steps the value-tier duct fan up to a 6-inch collar, moving more air through ducting for a larger closet or equipment room while keeping the same dial-style manual speed control as the A4. Its mixed-flow impeller design keeps airflow steady against duct resistance instead of stalling like a plain axial fan.

Dual ball bearings rated for 67,000 hours back the motor, and it runs from a standard 100-240V AC supply. It is a straightforward, lower-cost option for anyone who wants a duct-mounted exhaust fan without the temperature or humidity automation of the S or T models.
