AC Infinity - Rack fan kit - roof mountable - AC 100-240 V - 120 mm - 19"

Key Features and Benefits: Precise speed controllerThe inline speed controller enables you to set the duct fan's speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppress voltage to control fan speeds, this duct fan features a DC-motor that is precisely controlled using PWM (Pulse Width Modulation). This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight speed settings are available with power switch, and backup memory. Performance and applicationsThis rack roof fan kit contains standard 120mm fans, enabling it to be compatible with most standard 19" racks. With a noise level of 26 dBA, the fan system can be used for environments where low or minimal noise is required such as home theater, studio, DJ, and audio video racks. A max airflow rating of 200 CFM will provide sufficient cooling to server, network, IT and equipment racks requiring high airflow.
