Effectively Manage Bypass Air at the Raised Floor Level

Managing airflow through the horizonal plane of the raised floor is known as Raised Floor Airflow Management (AFM). Raised floor AFM ensures that the cooling capacity in a data center room is properly delivered to the cold aisle.

CEG offers a wide array of products for a raised floor environment that contribute to more efficient airflow and cooling – especially when they’re part of an aisle containment system.

Raised Floor AFM Best Practices

Raised Floor

Seal all openings in the raised floor (except for supply panels).


Manage the type, location, and quantity of floor tiles in your environment. An airflow panel should provide enough cooling air in front of a rack(s) to ensure servers remain at safe operating temperatures without overcooling.


Consider your physical room space, leveling issues, weight loads, and equipment airflow ratings when determining which floor tiles, containment accessories, and sensors are right for your critical environment.

Stratification fins direct chilled air to balance airflow, eliminate hot spots.
Hybrid panels can reduce aisle space from 4’ to 3’.
Load ratings from 1000lbs to 5000lbs.
Varying surface types – powder coated, high-pressure laminate, aluminum.

Airflow Panels

Cement filled, wood core, solid steel.
Clearview allows for convenient underfloor viewing.
Load ratings from 1000lbs to 5000lbs

Solid Floor Panels

Understand static pressure loss or fluctuation.
Balance cooling airflow
Increase available datapoints for better infrastructure insight.
