Vertiv VC-AC-0004 Aisle Containment 31.5 Blanking Panel | Rack Enclosure

Open rack spaces are a direct path for wasted cooling. The Vertiv VC-AC-0004 blanking panel addresses that problem by covering unused 31.5 in openings and helping maintain the pressure and airflow discipline that containment strategies depend on. In high-density environments, even small gaps can undermine the performance of a carefully tuned cooling design. This accessory helps reduce recirculation, limit bypass airflow, and keep conditioned air focused on live equipment rather than escaping through empty rack units. The result is a cleaner thermal profile and better use of the cooling capacity already in place. For infrastructure teams, this is a low-complexity, high-value control point. It supports better airflow management without changing the rack architecture or adding active components. Use it where precision matters: in rows that mix populated and partially populated cabinets, in phased deployments, or anywhere thermal consistency is worth protecting.
