Middle Atlantic DWRSR-6-FK DWR/SR Series Active Fan Kit
Overview
The Middle Atlantic DWRSR-6-FK is an active thermal management kit designed to force 440 CFM of airflow through DWR and SR series rack enclosures running 26–32 inches deep. That 440 CFM output is meaningful in practice: a loaded AV or security rack with NVRs, encoders, and power distribution can easily generate enough heat to shorten component lifespan or trigger thermal shutdowns — a 6-inch, 120 VAC fan at this airflow rating keeps operating temperatures in check without requiring external cooling infrastructure. The DWRSR-6-FK slots into the existing rack structure, converting passive ventilation into active forced-air cooling using standard 120 VAC power, so no DC power conversion or additional wiring runs are needed beyond a nearby AC outlet.
Compatibility
The DWRSR-6-FK is purpose-built for Middle Atlantic Middle Atlantic rack enclosures in the DWR (Deskwall Rack) and SR series, specifically units with 26–32 inches of interior depth. It is not rated for international use (120 VAC only — 240 VAC markets require a separate solution). Verify your rack depth falls within that 26–32 inch window before ordering; shallower DWR or SR configurations use a different fan kit model. For integrators building out rack accessories and thermal management across a broader Middle Atlantic catalog, confirm the base series designation on the rack nameplate matches DWR or SR before specifying this kit.
Installation Notes
The kit draws 120 VAC and weighs 5 lbs (2.3 kg) installed — account for that load when calculating total rack weight, particularly in wall-mount DWR deployments where structural capacity matters. Power connection requires a standard 120 VAC source inside or adjacent to the enclosure. No special tools are listed in the evidence beyond standard rack installation hardware. The unit is not available for international shipping and is intended for domestic 120 VAC installations only.
