Unique Design allows for Easy Installation
AisleLok Modular Containment was developed to help data center managers achieve similar results to traditional containment (i.e. improved inlet temperatures), without all the complexities of measuring, designing, and installing. The unique design of the AisleLok modular aisle containment system attaches to the racks magnetically, creating a truly tool-less design that can be moved, reconfigured and reused as many times as needed.
The two main components of the AisleLok Modular Containment are the Rack Top Baffle and the Bi-Directional Doors, with an optional row gap filler. The Rack Top Baffle can be purchased in either a 30° angle from horizontal position (best for cold aisle containment), or in a vertical 90° angle from horizontal position (best for hot aisle containment). Both components attach directly to the racks. The open-sealing design ensures fire safety with an elegant appearance that brings professional aesthetics to your server room.
