Middle Atlantic MW-4QFT-FC Rackmount Fan Top 4-fan with Control

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND MW-4QFT-FC is a rackmount fan top assembly designed to provide active cooling for enclosed equipment racks and cabinets. This unit incorporates four 4.5-inch fans mounted in a top-panel configuration, paired with an integrated fan speed controller. The fan speed control allows technicians to balance airflow and acoustics based on the thermal load inside the rack. This assembly is installed by AV integrators, IT technicians, and low-voltage contractors managing heat-sensitive equipment in rack enclosures.

The MW-4QFT-FC is suited for rackmount enclosures where passive ventilation is insufficient and active top-exhaust airflow is required. Typical applications include audio-visual equipment racks, network equipment enclosures, and broadcast or data center cabinets that house amplifiers, switchers, routers, and similar heat-generating gear. The fan top mounts at the top of the rack to exhaust warm air upward and out of the enclosure, maintaining safe operating temperatures for installed equipment.

Key Features

• Four 4.5-inch fans provide active top-exhaust cooling for rack enclosures
• Integrated fan speed control allows airflow adjustment based on thermal load
• Top-panel mounting configuration exhausts heat efficiently out of the enclosure
• Designed for use in AV, network, and broadcast rack installations
• Sold as a single assembly unit

Compatibility

Designed as an OEM-style replacement and upgrade option for compatible Middle Atlantic rackmount enclosures and cabinets requiring active top-exhaust fan cooling. Verify rack dimensions and mounting compatibility before installation.

Installation Notes

Installation should be performed by a qualified low-voltage contractor or AV integrator familiar with rackmount equipment. Power down all equipment in the rack before installing or servicing the fan top assembly. Secure the unit to the rack frame per the manufacturer mounting guidelines and verify that all electrical connections to the fan speed controller are properly seated before restoring power. Follow applicable NEC requirements for low-voltage wiring within the enclosure.
