Middle Atlantic MW-10FT-550CFM 10-Inch Active Fan Top with Guards

Overview

The MW-10FT-550CFM is a 550 CFM active fan top unit designed to mount on Middle Atlantic rack enclosures and move enough air to protect densely loaded equipment — NVRs, managed switches, video servers — running 24/7 in telecom closets and security head-end rooms where passive convection falls short. At 120 VAC and an uncontrolled fixed-speed configuration, this is a straightforward thermal exhaust solution: install it, wire it, and let it pull heat out of the rack continuously. The steel construction and black finish match standard Middle Atlantic rack aesthetics.

Compatibility

The MW-10FT-550CFM is engineered for the Middle Atlantic MRK, VRK, VMRK, and WMRK series rack enclosures. Verify your enclosure's top-panel cutout dimensions before ordering — the unit's installed footprint is 21.7 in. wide × 25.06 in. tall (including the fan assembly height). This fan top is not a variable-speed or thermostatically controlled unit; if your installation requires temperature-triggered fan activation or speed ramping, look to controlled variants in the Middle Atlantic fan top line. Pair this with a managed PoE switch or similar active hardware in the rack to ensure the thermal load justifies the continuous airflow draw.

Installation Notes

Power requirement is 120 VAC — confirm your rack PDU or wall circuit can supply a dedicated AC feed. The unit is uncontrolled (no thermostat, no speed control), so it runs at full 550 CFM continuously once energized. At 16 lbs shipping weight, account for the added top-load when calculating rack stability, particularly on open-frame or lightly ballasted enclosures. Guards are included, so no separate fan guard sourcing is needed. Consult the Middle Atlantic rack accessories catalog for compatible blanking panels and cable management if you are building out a full thermal-management strategy in the same enclosure.
