Quiet Dual-Fans Cooling Kit for 19 AV/Network Racks

A quiet dual-fan kit designed to be mounted onto the roof of standard 19-inch racks has been created to provide cooling. This kit, which contains standard 120mm fans, can also replace existing fans that may have been included with your rack. Maintaining an optimal temperature for rack-mount equipment prevents overheating, ensures constant performance, and extends their lifespan.

The kit features an inline speed controller utilizing PWM-technology, enabling 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 allows the fan's motor to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers. Eight speed options are available with a power switch, and backup memory.

The fans are housed in heavy-duty cold rolled steel with spiral fan guards. They are CE and RoHS certified, containing dual-ball bearings that are rated at 67,000 hours and allow this fan system to be mounted horizontally or vertically. This complete kit includes two fans, an inline speed controller, rack-roof mounting screws, four rubber washers, a corded 6-ft power adapter, and a user's manual.

The 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.

The kit is designed to be compatible with CLOUDPLATE series rack fans and can be linked to share the same programming, making it a versatile solution for cooling your rack-mount equipment.
