Cool the same load with half the airflow

DirectAire® uses patent pending technology to angle the air toward the equipment achieving a 93% Capture Index. This means 93% of the airflow delivered through the airflow panel is entering the face of the server rack, providing the highest cooling capacity and energy efficiency of any airflow panel on the market. DirectAire® has a 68% open area and a strong durable design that provides superior load performance. DirectAire® is designed for a one-to-one paring with a standard 42U rack.

Key Performance Characteristics

  • Welded steel grate design
  • 68% open area delivers 1,227 L/s at 25 Pa
  • Cools over 19kW per rack at 25 Pa
  • 11.1 kN design load performance
  • Directional airflow for 93% Capture Index
  • Manual and automatic airflow controls options


The elimination of bypass air saves operating expenses in existing facilities and reduces capital expenditures on cooling equipment in new facilities. DirectAire superior load performance is ideal for retrofit and new construction, easily integrating into your existing raised floor system.

Improve Data Centre Financial Performance

Directional airflow panels maximize the financial performance of any new or existing data center. The precise delivery of air provides many financial benefits for new and existing facilities.

  • Reduces bypass airflow by over 40% allowing new facilities to reduce the number of CRAH units.
  • Retrofits can set CRAH units with fixed speed fans to standby mode or adjust variable fan drives to operate at a lower static pressure, saving up to 40% in annual fan energy.
  • 93% Capture Index eliminates the need for costly aisle containment systems
  • Improves overall cooling capacity allowing for the addition of IT equipment without capital investment on infrastructure.

Easily Cool High Density Racks

DirectAire features a 68% open area, capable of delivering 2,600 CFM at .1" H2O static pressure. Each vertical vane has an angle of deflection at the top to direct the airflow toward the server rack to achieve a 93% Capture Index rate, compared to the typical airflow panels which only deliver 30-50% directly to the rack. This improvement enables DirectAire to efficiently cool up to 25kW per rack.
