Middle Atlantic MW-4QFT-FC Integrated 4-Fan Rack Top with Controller

Overview

The MW-4QFT-FC is an active fan top assembly for Middle Atlantic rack enclosures, moving 220 CFM through four quiet fans to clear heat from densely packed AV and security equipment. Controlled airflow — rather than passive venting — matters in closed rack builds where switches, NVRs, and PoE injectors generate sustained thermal load. The unit runs on 120 VAC and includes a built-in fan controller, so you can dial airflow to match actual heat output rather than running fans at full speed around the clock. Steel construction with a black finish keeps it consistent with the enclosures it tops. At 21.7 in. wide and 25.06 in. tall (including the assembly profile), confirm rack and room clearances before ordering.

Compatibility

Designed for Middle Atlantic rack enclosures in the MRK, VRK, VMRK, and WMRK series — the fan top drops onto the top panel opening of these enclosures and integrates with their mounting structure. It is not a universal fit; verify your enclosure series against Middle Atlantic's fan top compatibility matrix before purchasing. This fan top is suited for rack enclosure deployments in security head-end rooms, AV equipment closets, or any enclosed rack installation where convective cooling alone is insufficient. If you're pairing this with a new enclosure build, review the rack cooling accessories category for blanking panels and cable management that contribute to proper airflow channeling.

Installation Notes

Requires a 120 VAC power feed at the rack location — plan your outlet placement accordingly. The fan controller is included; no separate controller purchase is needed. Shipping weight is 18 lbs, so a two-person install is practical when positioning on top of a fully populated rack. Verify the enclosure top panel cutout dimensions match the 21.7 in. width of the MW-4QFT-FC before installation.
