KoldLok 10012 Extended Brush Grommet

Upsite Technologies KoldLok 10012 Extended Raised Floor Grommets are designed to seal a variety of existing perimeter openings, with the added flexibility of modification for large and unique openings.  Based on measurements at multiple data centers, 50-80% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings. This lost air, known as bypass airflow, contributes to IT equipment hotspots, cooling unit inefficiencies, and increasing infrastructure costs. KoldLok products specifically address bypass airflow and its detrimental effects on data center cooling.

Note: The Raised Floor Grommets are sold in a pack of 10.
