Middle Atlantic 100 CFM DC Fan Kit for BRK and MBRK Series Racks

The DCFANKIT-4 from Middle Atlantic is a precision-engineered cooling solution designed to protect laminated racks from heat buildup while preserving performance and longevity. This intelligent DC fan kit is purpose-built for BRK and MBRK Series racks and is highly compatible with RK/BRK and RDR configurations, making it a versatile choice for professional AV, IT, and control-room installations. With four high-efficiency fans delivering substantial airflow and thermostatic control, the kit maintains stable temperatures even in dense, equipment-heavy enclosures. By balancing cooling power with quiet operation, the DCFANKIT-4 helps prevent thermal throttling, reduces wear on components, and supports uptime for critical gear ranging from processors and routers to amplifiers and power management modules. The kit’s compact, rack-friendly design means it installs neatly in standard 19-inch racks, preserving space for cables and other hardware while delivering dependable, consistent cooling where you need it most.

• Intelligent thermostatic cooling: The DCFANKIT-4 uses built-in temperature sensing to automatically adjust fan speeds. As rack temperatures rise, the thermostatic control increases airflow to keep internal components within safe operating limits. When temperatures drop, the system scales back, delivering energy-efficient cooling without unnecessary fan noise or power draw. This smart regulation helps maintain stable performance and reduces the risk of overheating during peak workloads or long-duration sessions.
• Four 100 CFM DC fans for robust airflow: Each fan is rated for up to 100 CFM in free air, delivering a powerful, evenly distributed flow across the rack interior. The four-fan configuration creates a uniform cooling envelope that mitigates hot spots around dense equipment clusters. Combined with thermostatic regulation, this setup ensures consistent cooling across multiple devices, from rack-mounted servers to AV processors, without overworking the fans.
• Ready-to-install compatibility with BRK, MBRK, RK/BRK, and RDR series racks: This kit is designed for seamless integration with Middle Atlantic’s BRK and MBRK lines and is compatible with related RK/BRK and RDR configurations. It ships with essential mounting hardware and harnessing, enabling a straightforward, tool-light installation in standard 19-inch rack spaces. The kit’s modular design supports clean cable management and preserves precious rack real estate for primary equipment while delivering effective cooling performance.
• Enhanced reliability and long-term protection: By actively controlling rack temperature, the DCFANKIT-4 minimizes thermal stress on power supplies, line drivers, routers, and other sensitive electronics. Reduced thermal cycling can extend component life, lower replacement costs, and improve overall uptime in demanding environments. The sturdy, purpose-built construction is engineered to withstand continuous operation in professional installations, while the thermostatic system reduces wear on the fans themselves by preventing unnecessary high-speed operation.
• Quiet operation with energy efficiency: Intelligent speed modulation keeps noise to a minimum during periods of lower thermal demand, a crucial feature for environments where noise sensitivity matters. The DC motor design also contributes to energy efficiency, helping to lower power consumption without sacrificing cooling performance. This combination of quiet, efficient cooling makes the DCFANKIT-4 suitable for control rooms, studios, classrooms, and silent-server rooms where performance must be balanced with a calm acoustic footprint.

How to Install Middle Atlantic 100 CFM DC Fan Kit for BRK and MBRK Series Racks

Installing the DCFANKIT-4 is designed to be a straightforward, low-disruption process that preserves rack space and minimizes downtime. Before you begin, ensure that all equipment is powered down and safely disconnected from the mains. Assess the rack interior to determine the optimal placement for the four fans, typically at positions that promote direct airflow across the hottest equipment bays. The kit’s mounting hardware is selected to fit standard 19-inch rack frames, with consideration given to proximity to heat-generating devices to maximize cooling effectiveness.

• Step 1 — Plan and prepare: Identify the hottest modules and map out fan placement to achieve an even cooling gradient. Confirm clearance behind panels and around cables to prevent interference with airflow. Gather all included mounting brackets and wiring harnesses, along with required tools for installation.
• Step 2 — Mount the fans: Secure the four fans into the rack using the supplied brackets and hardware. Position them to create a directional airflow path that moves hot air away from heat-generating devices. Ensure each fan is firmly mounted and free of vibration that could amplify noise or degrade performance.
• Step 3 — Connect the thermostat and power: Connect the thermostatic control leads per the included installation guide. Route power cables with care to maintain clean cable management and avoid pinch points. If your rack uses a centralized power distribution system, verify compatibility and avoid overloading circuit branches.
• Step 4 — Calibrate and test: Power up the rack and monitor initial fan activity. Check that the thermostat engages and that fans respond to rises in temperature. Observe airflow through the rack to confirm there are no dead zones and adjust fan positions if necessary to optimize coverage.
• Step 5 — Finalize setup: Tidy all wiring with cable ties or Velcro fasteners, reinstall any removed panels, and document the installation for future maintenance. If your environment requires monitoring, consider integrating the kit’s thermostatic function with existing environmental monitoring tools to maintain proactive cooling and alerting.
