Keep heat where it belongs: out of the rack path and away from sensitive electronics. Vertiv VRA2011 Vertical Exhaust Duct Short is designed to guide exhaust air upward and away from the equipment zone, helping maintain more consistent inlet conditions in compact, high-density installations. This short-form duct is a practical fit for environments where thermal management must be precise but space is limited. By shaping exhaust flow instead of allowing it to recirculate, it supports better cooling efficiency and reduces the risk of hot spots that can affect performance or shorten component life. The 800 W rating makes it suitable for targeted rack deployments where airflow control is part of the system design, not an afterthought. For infrastructure teams, the value is in predictability. A ducted exhaust path can improve thermal discipline in racks that run close to capacity, especially when equipment is tightly packed or installed in rows with limited clearance. Vertiv’s rack accessory approach keeps the solution focused: simple, purpose-built, and aligned to the demands of enterprise environments that cannot afford thermal drift.
