Middle Atlantic MW-4FT Fan Top Rackmount Accessory

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND MW-4FT is a fan top assembly designed to mount four 4.5-inch fans in a rackmount enclosure. This accessory attaches to the top of compatible rack cabinets to provide active exhaust ventilation for heat-sensitive equipment installed in the rack. It is typically specified by AV integrators, IT infrastructure technicians, and low-voltage installers managing thermal loads in rack systems. The MW-4FT is sold as a single unit and is categorized as a rackmount accessory for use in structured wiring and equipment rack applications.

The MW-4FT is suited for use in rackmount enclosures where passive ventilation is insufficient to manage heat generated by amplifiers, network switches, patch panels, or other rack-mounted equipment. It is commonly installed in equipment rooms, server closets, and AV racks in both residential and light commercial settings where consistent airflow across installed components is required.

Installation Notes

Installation should be performed by a qualified low-voltage or AV systems technician. Power down all rack-mounted equipment before installing or servicing the fan top assembly. Follow the enclosure manufacturer instructions for securing the fan top panel and making any electrical connections to the rack power distribution unit. Verify that fan airflow direction aligns with the intended exhaust path for the enclosure.
