AC Infinity Rack ROOF Fan KIT for AV, Home Theater, and Network 19 Racks

Designed for standard 19-inch racks, this quiet dual-fan kit can be mounted on the roof or used to replace existing fans. Featuring a speed controller utilizing PWM technology, it can adjust the fan speed without generating additional noise. Compatible with CLOUDPLATE series rack fans, the kit can be linked to share the same programming. Constructed with heavy-duty cold rolled steel, it includes spiral fan guards, mounting hardware, and a power adapter.

This complete kit contains two standard 120mm rack fans, an inline speed controller, rack-roof mounting screws, four rubber washers, a 6-ft power adapter, and a user manual. The fans are CE and RoHS certified, and feature dual-ball bearings rated for 67,000 hours, allowing them to be mounted horizontally or vertically.

The inline speed controller enables users to set the fan speed to optimal noise and airflow levels for different environments. Unlike common AC-powered duct fans that use voltage suppression to control speed, this system features a DC motor precisely controlled using Pulse Width Modulation (PWM) technology. This allows the motor to run smoothly at very low RPM speeds without the noise and heat issues seen with variable voltage controllers. Eight speed options are available, with a power switch and backup memory.

With a maximum airflow of 200 CFM and a noise level of 26 dBA, this rack roof fan kit is suitable for use in environments requiring low or minimal noise, such as home theaters, studios, DJ booths, and AV racks. The high airflow capacity makes it suitable for cooling server, network, IT, and other equipment racks that require significant cooling.
