115V Fan 4 1/2 Inch, 50 CFM at 30dBA
4.5 inch active rack fan providing 50 CFM airflow at 30dBA for quiet thermal management
The Middle Atlantic QFAN is a 4.5 inch (11.4 cm) active fan designed for rack-based thermal management. Operating on 120 VAC, this unit delivers 50 CFM of airflow with a noise rating of < 30dBA. The fan features a smooth, ball-bearing design to ensure extra quiet operation during continuous use. This component is 1.5 in (3.8 cm) deep, with a physical footprint of 4.69 in (11.9 cm) in both height and width. For protection, the unit includes a black powder-coated fan guard. This TAA compliant accessory is an active component type that ships with the necessary mounting hardware and power cord required for installation. Because it is an active fan without a built-in controller, installers may choose to add a thermostatic controller like the FC-4-1CA to automate cooling based on temperature changes.
