Middle Atlantic DC Fan Kit - 138 CFM, 4.5in DC Fans

The FAN2-DC DC Fan Kit from Middle Atlantic is a purpose-built cooling solution designed to protect rack-mounted equipment from heat-related performance throttling and premature wear. Engineered for reliability in demanding environments, this kit combines two compact 4.5-inch DC fans to deliver a total airflow of 138 CFM, ensuring hot components receive steady, focused cooling where it matters most. Whether you’re equipping a high-density server rack, a telecom cabinet, or a music studio rack with critical gear, this fan kit delivers consistent cooling with minimal noise, making it ideal for data centers, recording studios, and mission-critical IT rooms alike.

• Efficient dual-fan design delivers a robust 138 CFM of total airflow. The two 4.5-inch DC fans work in harmony to push cool air across hot components, helping to prevent thermal throttling, extend equipment life, and maintain stable performance even as rack density increases. This targeted airflow is particularly effective at cooling hot spots around power supplies, routers, switches, and blade servers that tend to heat up under load.
• Low-noise operation for environments where silence matters. While maximizing cooling, the FAN2-DC kit is designed to operate quietly, reducing ambient noise in data centers, editing suites, broadcast rooms, and other professional spaces. The result is reliable cooling without distracting fan noise, so teams can focus on work without being interrupted by loud equipment.
• Compact 4.5-inch footprint for flexible mounting. The slim form factor makes it easy to integrate into most 19-inch racks and blank panels without crowding adjacent equipment. This compact design also simplifies installation in tight enclosures, allowing you to position fans where cooling is most needed without sacrificing rack space for other devices.
• Durable, DC-powered performance. Built for continuous operation in demanding environments, these fans run on a DC power supply for stable, efficient cooling. The DC design reduces energy waste and heat generation while delivering consistent air movement across the rack. This makes the FAN2-DC kit a dependable choice for uptime-critical applications that require steady airflow.
• Easy installation with included hardware and flexible configuration. The kit ships with mounting hardware and straightforward wiring options, enabling quick installation with minimal tools. The dual-fan arrangement supports both push and pull orientation, giving you the flexibility to tailor airflow direction to your rack layout and cooling strategy as your gear evolves.

How to install Middle Atlantic DC Fan Kit

• Plan your cooling layout. Assess the rack and identify hot zones around power supplies, network gear, and high-density servers. Determine whether you will mount the fans to push air through or pull air across equipment, and choose a location that maximizes direct airflow to those hot spots while keeping wiring tidy.
• Power down and disconnect equipment. Before removing panels or mounting fans, ensure all devices are powered down and unplugged. This reduces risk and protects both personnel and equipment during installation.
• Prepare the mounting area. If your rack has blank panels or unused bays, remove the appropriate panel and prepare the mounting surface. The 4.5-inch fans are designed to fit into standard 19-inch rack spaces, so align the fans with available slots to maintain proper depth and clearance for cables and other components.
• Install the fans. Use the supplied hardware to secure each 4.5-inch DC fan firmly in place. Ensure that the fan blades have clear clearance from any adjacent components and that the airflow direction matches your intended push/pull configuration. Tighten mounting screws evenly to avoid vibration and noise.
• Connect the wiring. Connect the fans to a DC power supply using the included harness or wiring method. Route cables neatly along the rack rails, using cable ties or velcro to minimize snag hazards and maintain unobstructed airflow. If your rack uses a centralized power distribution system, ensure compatibility and proper grounding.
• Test airflow and adjust. Restore power and verify that both fans are operating smoothly without excessive vibration or unusual noises. Check for uniform airflow across the rack and adjust the orientation if needed to optimize cooling for hot spots. Confirm that the fans are not interfering with door swings or other rack accessories.
• Monitor performance over time. After installation, monitor system temperatures and fan performance during peak loads. If you notice hotspots or rising temperatures, consider repositioning the fans or adding additional cooling accessories to maintain consistent thermal margins across the enclosure.
