Vertiv E428014 Vertical Airflow Baffle Brush Kit 42U x 800W | Rack Cooling

Keep rack airflow under control in dense 42U x 800W enclosures with this Vertiv vertical airflow baffle and brush kit. Designed to help separate hot and cold air paths inside the cabinet, it reduces bypass airflow that can undermine cooling performance and create uneven thermal conditions across installed equipment. For infrastructure teams managing high-density deployments, small airflow losses can translate into hotter components, more fan activity, and less efficient use of cooling capacity. This baffle helps close those gaps so conditioned air reaches the equipment that needs it, rather than escaping into unused rack space. The brush kit adds a practical seal around cable pathways, supporting cleaner airflow management without complicating service access. It is a straightforward fit for environments where rack-level thermal discipline matters: colocation cabinets, enterprise server rooms, and mixed-vendor racks with active cable routing. When the cost of poor airflow is downtime, throttling, or reduced hardware life, a purpose-built airflow accessory is a low-friction way to protect the investment already in the rack.
