Middle Atlantic High CFM Split Rear Door, 44 RU DRK Racks

The Middle Atlantic High CFM Split Rear Door is engineered to safeguard your valuable AV and IT equipment from the proliferating heat generated by servers, NVRs, and DVRs. Built to integrate with 44 RU DRK racks, this cupboard-style, split rear door features an adjustable, six-fan High CFM system that actively extracts hot air from the back of the cabinet and channels it toward return air ducts. By combining robust construction with intelligent airflow management, this door helps maintain optimal operating temperatures, extend equipment life, and improve overall system reliability in demanding data centers, telecommunication rooms, and broadcast environments. Whether you’re deploying dense server blades, high-traffic NVR deployments, or multi-camera DVR ecosystems, the High CFM Split Rear Door delivers reliable cooling performance without sacrificing rack space or access. Its design emphasizes ease of maintenance, flexible airflow configuration, and seamless integration with existing Middle Atlantic enclosures, making it an essential upgrade for organizations seeking to tame heat and reduce energy waste in modern racks.

• High-efficiency cooling with adjustable six-fan system: The door’s six high-CFM fans pull hot air away from the rear cabinet surface and expel it toward return air channels. Fan placement is adjustable, enabling you to optimize airflow to match your specific equipment layout and heat load, ensuring thorough cooling where it’s needed most while preserving quiet operation in office or studio environments.
• Universal compatibility with 44 RU DRK racks: Designed to fit Middle Atlantic 44 RU DRK series racks, this split rear door provides a secure, space-saving cooling solution that integrates seamlessly with the cabinet’s existing hardware. The cupboard-style construction preserves unobstructed access to rear cabling while delivering superior thermal performance for dense equipment configurations.
• Durable, purpose-built construction: Crafted from heavy-duty steel with a durable powder-coated finish, the High CFM Rear Door stands up to demanding conditions typical in data centers, server rooms, and broadcast facilities. The split door arrangement simplifies service and maintenance, allowing technicians to remove or service electronics without exposing the entire cabinet interior to ambient dust or debris.
• Enhanced air management and energy efficiency: By directing hot air toward return air ducts and enabling precise fan placement, the door minimizes recirculation and reduces the workload on cooling systems. The result is improved thermal management, lower energy costs, and decreased risk of overheating-related equipment failures. This solution is particularly advantageous in rooms with limited floor space where efficient airflow is crucial.
• Easy integration, installation, and ongoing maintenance: The split rear door is designed for simple installation onto compatible Middle Atlantic racks, with straightforward wiring and mounting. The adjustable fans and modular door design enable quick servicing, simple filter maintenance (where applicable), and future scalability as your rack density evolves. It’s an investment that pays dividends in reliability and uptime for critical IT and AV infrastructure.

how to install [product]

• Turn off and power down equipment inside the rack and disconnect any connected devices to ensure a safe installation environment. Prepare the rack per manufacturer guidelines and clear the rear workspace for the door mounting process.
• Remove the existing rear door (if applicable) and verify that your rack frame is clean, aligned, and ready for the split rear door installation. Confirm that the mounting rails and hinges are in good condition to support the new door assembly.
• Position the High CFM Split Rear Door with the six fans facing inward toward the cabinet interior. Align hinge points and mounting holes with the rack’s rear frame. Begin securing the door using the supplied hardware, ensuring that the door sits plumb and evenly along the cabinet edge.
• Connect power to the fan assembly following the included wiring diagram and your facility’s electrical standards. If the door supports separate fan power options or speed control, configure the intended power source and verify that all fans power up without obstruction. Route cables neatly to minimize airflow interference and ensure easy access to cabling behind the door.
• Adjust fan placement as needed to optimize airflow for your equipment mix. Test with the rack populated to simulate real operating conditions, monitoring intake and exhaust temperatures at various points inside the cabinet. Confirm that hot air is effectively drawn from the rear and guided toward return air ducts, and verify that the door closes fully without binding or interference with any rear cables or devices.
• Perform a final inspection, confirm that fasteners are tight, and verify that there are no obstructions to airflow. Restore power to equipment and observe thermal behavior during a controlled load test. Document any adjustments for future reference and routine maintenance.
