Air Flow Seals

Innovative solutions manage airflow in and around server cabinets to maximize cooling efficiency

MagSeal Magnetic Air Dams

Magseal Magnetic Cabinet Footer Skirt


Data center managers who are serious about maximizing their cooling efficiency know that using blanking panels in unused rack spaces is critical for aisle containment. An overlooked final step in efficiency is sealing the space under server cabinets. Data centers that incorporate hot and cold aisle containment have pressure differentials between the aisles. This pressure can cause the gap below server cabinets, which is often 2” or more, to become an air stream between hot and cold aisles. The resulting mix of air reduces the effectiveness of a containment solution.

Cool Shield Expandable Foam Gap Seal

Single station control room furniture desk


The Cool Shield AirStrip is an expanding foam tape designed to prevent unwanted air loss from gaps in contained aisles, server rack rows and data center infrastructure. Strips can be used above or below containment panels, next to rack rails, under server cabinets or in gaps in raised flooring. Filling gaps significantly improves cooling efficiency by preventing bypass airflow and hot air recirculation.
