Vertiv VC-AC-0021 2 ft Brush Strip Aisle Containment | Rack Accessory

Keep conditioned air where it belongs with a brush strip accessory built for aisle containment environments. The Vertiv VC-AC-0021 is a 2 ft brush strip intended to help close off openings that would otherwise let cool air escape or hot exhaust recirculate. In high-density racks, small gaps can have outsized impact on thermal performance. This accessory supports cleaner airflow management by reducing bypass through cable entry points and other containment transitions. That matters when you are trying to protect cooling margins, stabilize inlet temperatures, and avoid paying for air that never reaches the load. For data centers under pressure to improve efficiency without reworking the room, brush strips are a practical detail with measurable value. They fit into containment planning as a low-profile component that supports better thermal separation, especially in rows with frequent cabling changes. The result is a more disciplined airflow path and a better foundation for consistent cooling performance.
