The 4" CLOUDLINE T4 Quiet Duct Fan System from AC Infinity is designed to quietly cool AV equipment rooms and closets, and to ventilate various air circulation and exhaust projects. Featuring an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. The system features a DC motor with PWM control for a quiet and energy efficient performance. The motor box containing the fan's impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. It is IP44 rated, making it highly resistant to dust and liquids, and performs well even in harsh environments.

The included intelligent controller features an on-board processor with active temperature monitoring that will automatically adjust fan speeds to respond to varying temperatures. For non-cooling ventilation applications, the controller can provide a readout of the duct fan's speed and status. The programming can be set to run continuously at customizable speeds with easy shut-off and power on-off memory. Additional features include an alarm system, eco-mode, display lock or off while programs are running, three backlight settings, and two buffer options.
