Vertiv Exhaust Chimney FAN Tray 1200 CFM 48IN D - GL-ECFT48

Vertiv GL-ECFT48 Exhaust Chimney Fan Tray

Overview

The Vertiv GL-ECFT48 is a 1200 CFM exhaust chimney fan tray designed for 48-inch-depth rack enclosures where passive airflow alone cannot maintain safe operating temperatures across dense compute or networking loads. Rather than relying on perforated doors and floor tile delivery alone, the GL-ECFT48 mounts at the top of the rack and actively draws hot exhaust air upward — a direct response to the hot-spot problem that develops in high-density rows when row-level containment isn't viable. If your deployment uses Vertiv rack cooling solutions or is part of a broader data center infrastructure refresh, this fan tray integrates into that thermal stack without requiring a separate controller enclosure.

Compatibility

The GL-ECFT48 is sized for 48-inch-deep rack enclosures. Buyers integrating this into a Vertiv rack and enclosure system should verify internal rail depth and top-panel knockout dimensions before ordering — chimney fan trays are dimension-sensitive and a 42-inch-deep cabinet will not accept a 48-inch tray without modification. Consult the Vertiv rack lineup (including the VR and VX series enclosures) to confirm depth compatibility with your specific cabinet model. For deployments using rack accessories such as cable management arms or patch panels mounted near the top-of-rack position, verify vertical clearance above the top U-space before installation.

Installation Notes

Chimney fan trays of this class typically mount to the top panel of the enclosure and exhaust directly into an overhead plenum or open ceiling. Confirm that your raised-floor or overhead containment system can accept 1200 CFM of hot exhaust without backpressure that would reduce effective airflow. Adequate plenum clearance and return path sizing are the two most common installation oversights on high-CFM tray deployments.
