Description

Middle Atlantic MW-4FT Fan Top

Overview

The Middle Atlantic MW-4FT is an active component designed to mount up to four 4-inch (10.2 cm) fans within WRK, MRK, or VRK rack enclosures. This steel fan top provides essential ventilation, managing thermal loads for sensitive AV or IT equipment and preventing performance degradation or component failure due to overheating. Its black steel construction ensures durability and integration with standard rack aesthetics.

Compatibility

This fan top is specifically designed for use with Middle Atlantic's WRK, MRK, and VRK series rack enclosures. It accommodates up to four 4-inch (10.2 cm) fans, allowing for flexible airflow configurations based on your thermal management needs. It is not a standalone cooling unit but a mounting accessory for compatible fan modules.

Installation Notes

Constructed from durable steel with a black finish, the MW-4FT requires installation into the top of a compatible Middle Atlantic rack. The unit itself is designed to mount fans, and the fans themselves would require separate power connections and mounting hardware. The overall height of the unit is 25.06 inches (63.7 cm), contributing to the overall rack height when installed.
