Middle Atlantic SR28-6-FK Thermal Fan Kit, 440 CFM
Overview
The SR28-6-FK is an active thermal management kit engineered specifically for Middle Atlantic SR28-series rack enclosures. When passive convection isn't enough — think densely loaded AV/security racks running NVRs, switches, and amplifiers in a closed equipment room — this kit forces 440 CFM of airflow through the enclosure to keep temperatures in check and protect gear from heat-related throttling or failure. The SR28-6-FK runs on 120 VAC and uses a 6-inch (15.2 cm) fan to move air actively rather than relying on heat rise alone. At 5 lbs, it's a straightforward drop-in addition to the SR28 chassis without meaningfully affecting the rack's weight budget. If your Middle Atlantic rack is running warm after a full equipment load, this is the purpose-built fix — not a universal fan tray that may or may not fit.
Compatibility
The SR28-6-FK is designed exclusively for the Middle Atlantic SR28 Base Series rack enclosures. Do not assume fit across other Middle Atlantic rack families (SRK, WM, or BGR series have different chassis dimensions and fan mounting points). Verify your enclosure is confirmed SR28-series before ordering. This kit is intended for the rack accessories ecosystem built around the SR28 platform — compatible thermal management accessories such as vented blanks, roof panels, or exhaust units from the same series can be paired to build a complete airflow path through the enclosure.
Installation Notes
The SR28-6-FK requires a standard 120 VAC power source — verify your rack's power strip or PDU has an available outlet before installation. Power type is AC only; there is no DC or PoE variant for this kit. This product is not available for international shipment — 120 VAC supply voltage limits use to North American installations. The component type is active, meaning the fan runs continuously when powered; factor that into noise planning for occupied spaces like control rooms or reception areas.
