What Is Air Containment Curtain?_
An air containment curtain is a physical partition, often made of vinyl or clear plastic strips, installed above or around server racks to prevent hot exhaust air from mixing with cold intake air. It is typically used in hot-aisle or cold-aisle containment systems to maintain temperature differentials and reduce cooling load. Proper installation ensures that cooling airflow is directed precisely where needed, avoiding recirculation hotspots.
Technical Details
The curtain is mounted on a frame or track system above the aisle, with strips that hang down to seal gaps between racks or between racks and the ceiling. It relies on gravity and sometimes weighted strips to maintain a seal, but must be cut to fit around overhead cables or pipes without blocking airflow. The material is typically fire-retardant and static-dissipative to meet data center safety standards. Installation requires coordination with overhead cable trays and liquid cooling supply lines to avoid interference.
How Leviathan Systems Works with Air Containment Curtain
In our field deployments, air containment curtains are installed after rack assembly and before liquid cooling loop commissioning, often as a temporary measure during GPU rack bring-up to manage airflow before full containment doors are fitted. They are especially common in mixed-configuration racks where not all slots are populated, preventing bypass airflow.
