Isolation Racks are designed to minimize noise caused by loud computers and hard drive arrays, while maintaining proper operating temperature for equipment. These racks include a plexiglass front door, a gasketed solid rear door, as well as internal acoustical absorptive material to reduce noise. Additionally, the rear door features a built-in quiet fan and filter, and a brush grommet at the door bottom allows cable exit while maintaining a seal for noise and airflow. 48.06" H x 27.37" W x 31.50" D
