The AisleLok Under Rack Panel is the premium choice for your facility. Its revolutionary sealing technology was designed to allow easy modifications creating the flexibility to seal large and unique openings such as those found under various sized racks and cabinets.

Based on measurements at multiple data centers, on average 60% 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. AisleLok products specifically address bypass airflow and its detrimental effects on data center cooling.
