39873-700

The vertical exhaust duct provides a dedicated pathway for hot air to exit a ZetaFrame® cabinet, improving overall thermal performance. Its sealed design creates a reliable drop ceiling air return that isolates exhaust from surrounding equipment. This solution helps data‑center operators meet cooling efficiency targets while protecting sensitive hardware. Designed for cabinets with a depth of 41.3 in (1050 mm) or greater, the duct adjusts from 15 in to 20 in (381 mm‑508 mm) to match the distance to an overhead drop ceiling. The aluminum panels and plastic corners deliver durable construction, and the finish is available in black or Glacier White to match cabinet aesthetics. The part number 39873‑700 ensures compatibility with ZetaFrame® units and streamlines ordering. Airflow management is optimized by directing exhaust directly upward, reducing recirculation and lowering cooling costs. The flexible top seal accommodates minor variations in ceiling height, maintaining a tight seal for consistent performance. This vertical exhaust duct integrates with solid rear doors, bottom panels, and air directors for a complete containment strategy. Installation is straightforward, featuring a two‑piece design that bolts to the cabinet top and includes a brush‑sealed cable opening for power cords. An optional over‑track exhaust duct configuration can be added for extended routing needs in complex rack layouts. All required hardware is supplied, enabling rapid deployment without additional parts. By incorporating this exhaust cabinet accessory, facilities gain a scalable solution that supports high‑density deployments and future‑ready data‑center designs. The vertical exhaust duct enhances cooling reliability, simplifies maintenance, and aligns with CPI's commitment to quality and innovation.
